It runs from I-405 and State Route 22 (SR 22) in Seal Beach in Orange County to I-210 just south of the Irwindale – Duarte border in Los Angeles County. The San Gabriel River Freeway closely parallels the San Gabriel River for most of its alignment, hence its name, which is one of the few Southern California freeways not named after a city along its route.

Aside from changes to the interchange with I-105 (which did not open until the early 1990s), and the addition of an HOV lane between I-405 and I-10, I-605 is one of the only remaining freeways that kept its original alignment throughout its run through Los Angeles County since it first opened.

## Route description

The California Streets and Highways Code defines Route 605 as "(a) Route 1 near Seal Beach to Route 405. (b) Route 405 to Route 210 near Duarte." However, the portion in subsection A has yet to be constructed.

The southern terminus of I-605 is at the San Diego (I-405) and Garden Grove (SR 22) Freeways in Seal Beach. From there, it runs roughly north through the Gateway Cities of the Los Angeles Basin. It then shifts north-northeast, crossing the Whittier Narrows and across the San Gabriel Valley. I-605 then ends at its junction with the Foothill Freeway, (I-210) just south of the Irwindale – Duarte border. Ramps from I-605 then extend north to Huntington Drive in Duarte.

I-605 follows most of the length of the San Gabriel River from the San Diego Freeway in Seal Beach to the Santa Fe Dam. Typically dry riverbed and flood basins are visible from many portions of the route, especially near the northern terminus.

In the mid-2000s, a HOV lane was added for motorists with two or more people to use between I-405 and I-10. The HOV lane ends at I-10 and there are no plans to extend it to I-210 at this time. With the addition of the HOV lane, the left shoulder was eliminated to avoid massive costs to widen the freeway. The highway also suffers from traffic jams regularly, especially the junction with I-5 (the Santa Ana Freeway). Newer signs with exit numbers replaced the older signs between the Orange County line and I-10 in 2016, with the completion of the I-605 and I-10 junction improvement. I-605 is one of the only Southern California freeways without destinations (control cities) such as " Seal Beach " or " Irwindale " since its opening. Rather, cardinal directions ("NORTH" or "SOUTH"), and a simple "THRU TRAFFIC" designation in place of control cities, are used on signs along I-605 itself.

I-605 is part of the California Freeway and Expressway System, and is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration. I-605 from I-405 to I-10 is known as the San Gabriel River Freeway, as named by Senate Bill 99, Chapter 1101 in 1967.

## History

In 1957, the number for this route was proposed as I-13, as it is positioned approximately midway between I-5 and I-15 (although it intersects the former). That number was rejected, as was the second proposed number, I-102. Finally, the designation I-605 was accepted in 1958.

I-605 began construction in 1963 and the first section was opened in 1964 from I-405 to SR 60. The newest section (extension to I-210) was opened in 1971 was originally signed as SR 243. There are plans to extend it to SR 1 further south in Orange County as SR 605, but strong community opposition means that it is unlikely that the alignment will ever be built.

In 2020, there was a proposal to widen I-605, which would have added four new lanes to 12 mi (19 km) of I-605 between Norwalk and El Monte, California. This proposal was rejected due to strong community opposition, in particular due to the fact that it would have led to the destruction of houses in Downey, California.


C'était un rendez-vous

# C'était un rendez-vous

## Abstract

C'était un rendez-vous (English: It Was a Date) is a 1976 French short film directed by Claude Lelouch, showing a high-speed drive through Paris.

## Plot

The film shows an eight-minute drive through Paris during the early hours (05:30) of a Sunday morning in August (when much of Paris is on summer vacation), accompanied by sounds of a high-revving engine, gear changes and squealing tyres. It starts in a tunnel of the Paris Périphérique at Porte Dauphine, with an on-board view from an unseen car exiting up on a slip road to Avenue Foch. Well-known landmarks such as the Arc de Triomphe, Palais Garnier, and Place de la Concorde with its obelisk are passed, as well as the Champs-Élysées. Pedestrians are passed, pigeons sitting on the streets are scattered, red lights are ignored, one-way streets are driven up the wrong way, centre lines are crossed, and the car drives on the sidewalk to avoid a rubbish lorry. The car is never seen as the camera seems to be attached below the front bumper (judging from the relative positions of other cars, the visible headlight beam and the final shot when the car is parked in front of a kerb on Montmartre, with the famous Sacré-Cœur Basilica behind, and out of shot). Here, the driver gets out and embraces a young blonde woman as bells ring in the background, with the famous backdrop of Paris.

## Cast

- Gunilla Friden as La fille

- Claude Lelouch as L'homme (uncredited)

## Production

Shot in a single take, it is an example of cinéma vérité. The length of the film was limited by the short capacity of the 1000 foot 35mm film reel, and filmed from a (supposedly) gyro-stabilised camera mounted on the bumper of a Mercedes-Benz 450SEL 6.9. A photo has surfaced that seems to reveal an Eclair cam-flex 35mm camera with a wide angle lens, and a typical "speed rail" hard mount—no gyros—on a Mercedes. This model, which could reach a top speed of 235 km/h (146 mph), was only available with a three-speed automatic transmission. Lelouch drove his own car himself and claimed that the top speed achieved was around 200 km/h in the 1.3 km avenue Foch. Lelouch also claimed during a "making of" documentary that the soundtrack was dubbed with the sound of Lelouch's Ferrari 275GTB, which has the corresponding number of gears and a V12 sound that is quite distinct from that of any V8, including the 6.9 litre V8 of the alleged Mercedes camera car.

On the chosen course there were two people who knew to expect Lelouch. First there was Élie Chouraqui, his first assistant, who was posted with a walkie-talkie in the Rue de Rivoli, behind the archway exiting from the gardens of the Louvre palace, meaning to assist the driver at the only blind junction (archway); however, Lelouch has revealed that the radios failed, and if Chouraqui had tried to warn him of a pedestrian the message would not have been received. Anyway, the traffic light at that junction showed green. The other person who knew about his arrival was Lelouch's girlfriend Gunilla Friden. He'd told her he'd arrive within ten minutes at the Sacré-Cœur and asked her to appear upon his arrival.

## DVD release

In 2003, documentary filmmaker Richard Symons contacted Claude Lelouch and after six months of arduous talks, persuaded him the film should be restored from its original 35 mm negative and re-released on DVD. Symons' company Spirit Level Film now distributes the DVD worldwide.

## Route

The route was as follows: Bd Périphérique (exits at Porte Dauphine) · Av Foch · Pl Charles de Gaulle · Av des Champs-Elysées · Pl de la Concorde · Quai des Tuileries · Pl du Carrousel · R de Rohan · Av de l'Opéra · Pl de l'Opéra · Fromental Halévy · R de la Chausée d'Antin · Pl d'Estienne d'Orves · R Blanche · R Pigalle · Pl Pigalle · Bd de Clichy · (aborted turn at R Lepic) · R Caulaincourt · Av Junot · Pl Marcel Aymé · R Norvins · Pl du Tertre · R Ste-Eleuthère · R Azais · Pl du Parvis du Sacré Cœur.

The route measures 10.597 km long, which indicates an average speed of approximately 80 km/h (50 mph).

## Criticism

Comments attributed to Lelouch indicate that he acknowledges the public's "moral outrage" over his method of shooting this film. He also states that he was prepared to take the risks in making the film, but that he was also ready to drop it if he came across any unexpected risk (pedestrian, obstacle, etc.).

## In popular culture

The film was an inspiration for Criterion Games ' 2001 title Burnout, which would spawn the video game series of the same name.

In 2003, Nissan released a promotional DVD for the 350Z entitled The Run. It featured multiple camera views of a copper coloured 350Z driving through the streets of Prague, ending with a rendezvous with a beautiful woman.

In 2007, the film was used as the music video for Snow Patrol 's song " Open Your Eyes ".

In late 2009, a short film called The Fast and the Famous, directed by Jeremy Hart, was released on YouTube. The film features Jay Leno behind the wheel of a Mercedes-Benz SLS AMG. During his circuit of Mulholland Drive, Laurel Canyon Boulevard, Sunset Boulevard, Beverly Drive, and Coldwater Canyon Drive, Leno makes several references to Lelouch's classic film. In 2010, Jeremy Clarkson used the film as a basis for the opening scene of his DVD/Blu-ray The Italian Job.

In 2013, French indie pop band Phoenix used the film as a backdrop for live shows during the song "Love Like a Sunset Part I".

On 17 February 2017, Ford Motor Company in association with Claude Lelouch released a 360 degree view remake of the film using a Ford Mustang. Unlike the original, the 2017 version contains several cut scenes and does not show the entire (original) route of Lelouch's 1976 version.

In 2017, the British motoring show The Grand Tour produced an homage featuring a Bugatti Chiron driving across Turin in the episode "Bah Humbug-atti".

The 2018 video game Forza Horizon 4 features a story mission in which the player drives an Alpine A110 around the streets of Edinburgh for a short film in an homage to C'était un rendez-vous.

In the video game Burnout Paradise, the radio host DJ Atomika mentions how watching C'était un rendez-vous inspired him to enter the street racing scene.

In 2018, series 2 episode 8 ("Escape From Paris") of the Amazon series Patriot featured a drive across Paris with shots taken from a camera mounted low on the front of a car. This appears to be an homage to "C'était un rendez-vous". In later scenes it even includes inappropriate engine noise and tyre squeal, just like the original.

Christopher McQuarrie noted on the Empire Film Podcast that the film inspired multiple shots in his 2018 film Mission: Impossible - Fallout.

## Tribute film

In 2020 Lelouch filmed a tribute film of the film with assistance from Scuderia Ferrari entitled Le Grand Rendez-vous, this time set in Monaco instead of Paris and starring Monegasque Scuderia driver Charles Leclerc. Filming for the new version took place on the streets of Monte Carlo, featuring Leclerc driving a Ferrari SF90 Stradale. It took place on 24 May 2020, which was to have been the date of the Monaco Grand Prix that had been called off because of the global pandemic as only two major motorsport series had resumed competing as of that date. The film premiered on 13 June 2020.


Oganesson

# Oganesson

## Abstract

Oganesson is a synthetic chemical element; it has symbol Og and atomic number 118. It was first synthesized in 2002 at the Joint Institute for Nuclear Research (JINR) in Dubna, near Moscow, Russia, by a joint team of Russian and American scientists. In December 2015, it was recognized as one of four new elements by the Joint Working Party of the international scientific bodies IUPAC and IUPAP. It was formally named on 28 November 2016. The name honors the nuclear physicist Yuri Oganessian, who played a leading role in the discovery of the heaviest elements in the periodic table. It is one of only two elements named after a person who was alive at the time of naming, the other being seaborgium, and the only element whose eponym is alive as of 2024.

Oganesson has the highest atomic number and highest atomic mass of all known elements as of 2024. On the periodic table of the elements it is a p-block element, a member of group 18 and the last member of period 7. Its only known isotope, oganesson-294, is highly radioactive, with a half-life of 0.7 ms and, as of 2020, only five atoms have been successfully produced. This has so far prevented any experimental studies of its chemistry. Because of relativistic effects, theoretical studies predict that it would be a solid at room temperature, and significantly reactive, unlike the other members of group 18 (the noble gases).

## Introduction

### Synthesis of superheavy nuclei

A superheavy atomic nucleus is created in a nuclear reaction that combines two other nuclei of unequal size into one; roughly, the more unequal the two nuclei in terms of mass, the greater the possibility that the two react. The material made of the heavier nuclei is made into a target, which is then bombarded by the beam of lighter nuclei. Two nuclei can only fuse into one if they approach each other closely enough; normally, nuclei (all positively charged) repel each other due to electrostatic repulsion. The strong interaction can overcome this repulsion but only within a very short distance from a nucleus; beam nuclei are thus greatly accelerated in order to make such repulsion insignificant compared to the velocity of the beam nucleus. The energy applied to the beam nuclei to accelerate them can cause them to reach speeds as high as one-tenth of the speed of light. However, if too much energy is applied, the beam nucleus can fall apart.

Coming close enough alone is not enough for two nuclei to fuse: when two nuclei approach each other, they usually remain together for about 10 seconds and then part ways (not necessarily in the same composition as before the reaction) rather than form a single nucleus. This happens because during the attempted formation of a single nucleus, electrostatic repulsion tears apart the nucleus that is being formed. Each pair of a target and a beam is characterized by its cross section —the probability that fusion will occur if two nuclei approach one another expressed in terms of the transverse area that the incident particle must hit in order for the fusion to occur. This fusion may occur as a result of the quantum effect in which nuclei can tunnel through electrostatic repulsion. If the two nuclei can stay close past that phase, multiple nuclear interactions result in redistribution of energy and an energy equilibrium.

The resulting merger is an excited state —termed a compound nucleus —and thus it is very unstable. To reach a more stable state, the temporary merger may fission without formation of a more stable nucleus. Alternatively, the compound nucleus may eject a few neutrons, which would carry away the excitation energy; if the latter is not sufficient for a neutron expulsion, the merger would produce a gamma ray. This happens in about 10 seconds after the initial nuclear collision and results in creation of a more stable nucleus. The definition by the IUPAC/IUPAP Joint Working Party (JWP) states that a chemical element can only be recognized as discovered if a nucleus of it has not decayed within 10 seconds. This value was chosen as an estimate of how long it takes a nucleus to acquire electrons and thus display its chemical properties.

### Decay and detection

The beam passes through the target and reaches the next chamber, the separator; if a new nucleus is produced, it is carried with this beam. In the separator, the newly produced nucleus is separated from other nuclides (that of the original beam and any other reaction products) and transferred to a surface-barrier detector, which stops the nucleus. The exact location of the upcoming impact on the detector is marked; also marked are its energy and the time of the arrival. The transfer takes about 10 seconds; in order to be detected, the nucleus must survive this long. The nucleus is recorded again once its decay is registered, and the location, the energy, and the time of the decay are measured.

Stability of a nucleus is provided by the strong interaction. However, its range is very short; as nuclei become larger, its influence on the outermost nucleons (protons and neutrons) weakens. At the same time, the nucleus is torn apart by electrostatic repulsion between protons, and its range is not limited. Total binding energy provided by the strong interaction increases linearly with the number of nucleons, whereas electrostatic repulsion increases with the square of the atomic number, i.e. the latter grows faster and becomes increasingly important for heavy and superheavy nuclei. Superheavy nuclei are thus theoretically predicted and have so far been observed to predominantly decay via decay modes that are caused by such repulsion: alpha decay and spontaneous fission. Almost all alpha emitters have over 210 nucleons, and the lightest nuclide primarily undergoing spontaneous fission has 238. In both decay modes, nuclei are inhibited from decaying by corresponding energy barriers for each mode, but they can be tunneled through.

Alpha particles are commonly produced in radioactive decays because mass of an alpha particle per nucleon is small enough to leave some energy for the alpha particle to be used as kinetic energy to leave the nucleus. Spontaneous fission is caused by electrostatic repulsion tearing the nucleus apart and produces various nuclei in different instances of identical nuclei fissioning. As the atomic number increases, spontaneous fission rapidly becomes more important: spontaneous fission partial half-lives decrease by 23 orders of magnitude from uranium (element 92) to nobelium (element 102), and by 30 orders of magnitude from thorium (element 90) to fermium (element 100). The earlier liquid drop model thus suggested that spontaneous fission would occur nearly instantly due to disappearance of the fission barrier for nuclei with about 280 nucleons. The later nuclear shell model suggested that nuclei with about 300 nucleons would form an island of stability in which nuclei will be more resistant to spontaneous fission and will primarily undergo alpha decay with longer half-lives. Subsequent discoveries suggested that the predicted island might be further than originally anticipated; they also showed that nuclei intermediate between the long-lived actinides and the predicted island are deformed, and gain additional stability from shell effects. Experiments on lighter superheavy nuclei, as well as those closer to the expected island, have shown greater than previously anticipated stability against spontaneous fission, showing the importance of shell effects on nuclei.

Alpha decays are registered by the emitted alpha particles, and the decay products are easy to determine before the actual decay; if such a decay or a series of consecutive decays produces a known nucleus, the original product of a reaction can be easily determined. (That all decays within a decay chain were indeed related to each other is established by the location of these decays, which must be in the same place.) The known nucleus can be recognized by the specific characteristics of decay it undergoes such as decay energy (or more specifically, the kinetic energy of the emitted particle). Spontaneous fission, however, produces various nuclei as products, so the original nuclide cannot be determined from its daughters.

## History

### Early speculation

The possibility of a seventh noble gas, after helium, neon, argon, krypton, xenon, and radon, was considered almost as soon as the noble gas group was discovered. Danish chemist Hans Peter Jørgen Julius Thomsen predicted in April 1895, the year after the discovery of argon, that there was a whole series of chemically inert gases similar to argon that would bridge the halogen and alkali metal groups: he expected that the seventh of this series would end a 32-element period which contained thorium and uranium and have an atomic weight of 292, close to the 294 now known for the first and only confirmed isotope of oganesson. Danish physicist Niels Bohr noted in 1922 that this seventh noble gas should have atomic number 118 and predicted its electronic structure as 2, 8, 18, 32, 32, 18, 8, matching modern predictions. Following this, German chemist Aristid von Grosse wrote an article in 1965 predicting the likely properties of element 118. It was 107 years from Thomsen's prediction before oganesson was successfully synthesized, although its chemical properties have not been investigated to determine if it behaves as the heavier congener of radon. In a 1975 article, American chemist Kenneth Pitzer suggested that element 118 should be a gas or volatile liquid due to relativistic effects.

### Unconfirmed discovery claims

In late 1998, Polish physicist Robert Smolańczuk published calculations on the fusion of atomic nuclei towards the synthesis of superheavy atoms, including oganesson. His calculations suggested that it might be possible to make element 118 by fusing lead with krypton under carefully controlled conditions, and that the fusion probability (cross section) of that reaction would be close to the lead– chromium reaction that had produced element 106, seaborgium. This contradicted predictions that the cross sections for reactions with lead or bismuth targets would go down exponentially as the atomic number of the resulting elements increased.

In 1999, researchers at Lawrence Berkeley National Laboratory made use of these predictions and announced the discovery of elements 118 and 116, in a paper published in Physical Review Letters, and very soon after the results were reported in Science. The researchers reported that they had performed the reaction

In 2001, they published a retraction after researchers at other laboratories were unable to duplicate the results and the Berkeley lab could not duplicate them either. In June 2002, the director of the lab announced that the original claim of the discovery of these two elements had been based on data fabricated by principal author Victor Ninov. Newer experimental results and theoretical predictions have confirmed the exponential decrease in cross sections with lead and bismuth targets as the atomic number of the resulting nuclide increases.

### Discovery reports

The first genuine decay of atoms of oganesson was observed in 2002 at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, by a joint team of Russian and American scientists. Headed by Yuri Oganessian, a Russian nuclear physicist of Armenian ethnicity, the team included American scientists from the Lawrence Livermore National Laboratory in California. The discovery was not announced immediately, because the decay energy of Og matched that of Po, a common impurity produced in fusion reactions aimed at producing superheavy elements, and thus announcement was delayed until after a 2005 confirmatory experiment aimed at producing more oganesson atoms. The 2005 experiment used a different beam energy (251 MeV instead of 245 MeV) and target thickness (0.34 mg/cm instead of 0.23 mg/cm). On 9 October 2006, the researchers announced that they had indirectly detected a total of three (possibly four) nuclei of oganesson-294 (one or two in 2002 and two more in 2005) produced via collisions of californium -249 atoms and calcium-48 ions.

In 2011, IUPAC evaluated the 2006 results of the Dubna–Livermore collaboration and concluded: "The three events reported for the Z = 118 isotope have very good internalredundancy but with no anchor to known nuclei do not satisfy the criteria for discovery".

Because of the very small fusion reaction probability (the fusion cross section is ~ 0.3–0.6 pb or (3–6) × 10 m) the experiment took four months and involved a beam dose of 2.5 × 10 calcium ions that had to be shot at the californium target to produce the first recorded event believed to be the synthesis of oganesson. Nevertheless, researchers were highly confident that the results were not a false positive, since the chance that the detections were random events was estimated to be less than one part in 100 000.

In the experiments, the alpha-decay of three atoms of oganesson was observed. A fourth decay by direct spontaneous fission was also proposed. A half-life of 0.89 ms was calculated: Og decays into Lv by alpha decay. Since there were only three nuclei, the half-life derived from observed lifetimes has a large uncertainty: 0.89 +1.07 −0.31 ms.

The identification of the Og nuclei was verified by separately creating the putative daughter nucleus Lv directly by means of a bombardment of Cm with Ca ions,

and checking that the Lv decay matched the decay chain of the Og nuclei. The daughter nucleus Lv is very unstable, decaying with a lifetime of 14 milliseconds into Fl, which may experience either spontaneous fission or alpha decay into Cn, which will undergo spontaneous fission.

### Confirmation

In December 2015, the Joint Working Party of international scientific bodies International Union of Pure and Applied Chemistry (IUPAC) and International Union of Pure and Applied Physics (IUPAP) recognized the element's discovery and assigned the priority of the discovery to the Dubna–Livermore collaboration. This was on account of two 2009 and 2010 confirmations of the properties of the granddaughter of Og, Fl, at the Lawrence Berkeley National Laboratory, as well as the observation of another consistent decay chain of Og by the Dubna group in 2012. The goal of that experiment had been the synthesis of Ts via the reaction Bk(Ca,3n), but the short half-life of Bk resulted in a significant quantity of the target having decayed to Cf, resulting in the synthesis of oganesson instead of tennessine.

From 1 October 2015 to 6 April 2016, the Dubna team performed a similar experiment with Ca projectiles aimed at a mixed-isotope californium target containing Cf, Cf, and Cf, with the aim of producing the heavier oganesson isotopes Og and Og. Two beam energies at 252 MeV and 258 MeV were used. Only one atom was seen at the lower beam energy, whose decay chain fitted the previously known one of Og (terminating with spontaneous fission of Fl), and none were seen at the higher beam energy. The experiment was then halted, as the glue from the sector frames covered the target and blocked evaporation residues from escaping to the detectors. The production of Og and its daughter Lv, as well as the even heavier isotope Og, is also possible using this reaction. The isotopes Og and Og may also be produced in the fusion of Cm with Ti projectiles. A search beginning in summer 2016 at RIKEN for Og in the 3n channel of this reaction was unsuccessful, though the study is planned to resume; a detailed analysis and cross section limit were not provided. These heavier and likely more stable isotopes may be useful in probing the chemistry of oganesson.

### Naming

Using Mendeleev's nomenclature for unnamed and undiscovered elements, oganesson is sometimes known as eka-radon (until the 1960s as eka-emanation, emanation being the old name for radon). In 1979, IUPAC assigned the systematic placeholder name ununoctium to the undiscovered element, with the corresponding symbol of Uuo, and recommended that it be used until after confirmed discovery of the element. Although widely used in the chemical community on all levels, from chemistry classrooms to advanced textbooks, the recommendations were mostly ignored among scientists in the field, who called it "element 118", with the symbol of E118, (118), or simply 118.

Before the retraction in 2001, the researchers from Berkeley had intended to name the element ghiorsium (Gh), after Albert Ghiorso (a leading member of the research team).

The Russian discoverers reported their synthesis in 2006. According to IUPAC recommendations, the discoverers of a new element have the right to suggest a name. In 2007, the head of the Russian institute stated the team were considering two names for the new element: flyorium, in honor of Georgy Flyorov, the founder of the research laboratory in Dubna; and moskovium, in recognition of the Moscow Oblast where Dubna is located. He also stated that although the element was discovered as an American collaboration, who provided the californium target, the element should rightly be named in honor of Russia since the Flyorov Laboratory of Nuclear Reactions at JINR was the only facility in the world which could achieve this result. These names were later suggested for element 114 (flerovium) and element 116 (moscovium). Flerovium became the name of element 114; the final name proposed for element 116 was instead livermorium, with moscovium later being proposed and accepted for element 115 instead.

Traditionally, the names of all noble gases end in "-on", with the exception of helium, which was not known to be a noble gas when discovered. The IUPAC guidelines valid at the moment of the discovery approval however required all new elements be named with the ending "-ium", even if they turned out to be halogens (traditionally ending in "-ine") or noble gases (traditionally ending in "-on"). While the provisional name ununoctium followed this convention, a new IUPAC recommendation published in 2016 recommended using the "-on" ending for new group 18 elements, regardless of whether they turn out to have the chemical properties of a noble gas.

The scientists involved in the discovery of element 118, as well as those of 117 and 115, held a conference call on 23 March 2016 to decide their names. Element 118 was the last to be decided upon; after Oganessian was asked to leave the call, the remaining scientists unanimously decided to have the element "oganesson" after him. Oganessian was a pioneer in superheavy element research for sixty years reaching back to the field's foundation: his team and his proposed techniques had led directly to the synthesis of elements 107 through 118. Mark Stoyer, a nuclear chemist at the LLNL, later recalled, "We had intended to propose that name from Livermore, and things kind of got proposed at the same time from multiple places. I don't know if we can claim that we actually proposed the name, but we had intended it."

In internal discussions, IUPAC asked the JINR if they wanted the element to be spelled "oganeson" to match the Russian spelling more closely. Oganessian and the JINR refused this offer, citing the Soviet-era practice of transliterating names into the Latin alphabet under the rules of the French language ("Oganessian" is such a transliteration) and arguing that "oganesson" would be easier to link to the person. In June 2016, IUPAC announced that the discoverers planned to give the element the name oganesson (symbol: Og). The name became official on 28 November 2016. In 2017, Oganessian commented on the naming:

For me, it is an honour. The discovery of element 118 was by scientists at the Joint Institute for Nuclear Research in Russia and at the Lawrence Livermore National Laboratory in the US, and it was my colleagues who proposed the name oganesson. My children and grandchildren have been living in the US for decades, but my daughter wrote to me to say that she did not sleep the night she heard because she was crying.

The naming ceremony for moscovium, tennessine, and oganesson was held on 2 March 2017 at the Russian Academy of Sciences in Moscow.

In a 2019 interview, when asked what it was like to see his name in the periodic table next to Einstein, Mendeleev, the Curies, and Rutherford, Oganessian responded:

Not like much! You see, not like much. It is customary in science to name something new after its discoverer. It's just that there are few elements, and this happens rarely. But look at how many equations and theorems in mathematics are named after somebody. And in medicine? Alzheimer, Parkinson. There's nothing special about it.

## Characteristics

Other than nuclear properties, no properties of oganesson or its compounds have been measured; this is due to its extremely limited and expensive production and the fact that it decays very quickly. Thus only predictions are available.

### Nuclear stability and isotopes

The stability of nuclei quickly decreases with the increase in atomic number after curium, element 96, whose most stable isotope, Cm, has a half-life four orders of magnitude longer than that of any subsequent element. All nuclides with an atomic number above 101 undergo radioactive decay with half-lives shorter than 30 hours. No elements with atomic numbers above 82 (after lead) have stable isotopes. This is because of the ever-increasing Coulomb repulsion of protons, so that the strong nuclear force cannot hold the nucleus together against spontaneous fission for long. Calculations suggest that in the absence of other stabilizing factors, elements with more than 104 protons should not exist. However, researchers in the 1960s suggested that the closed nuclear shells around 114 protons and 184 neutrons should counteract this instability, creating an island of stability in which nuclides could have half-lives reaching thousands or millions of years. While scientists have still not reached the island, the mere existence of the superheavy elements (including oganesson) confirms that this stabilizing effect is real, and in general the known superheavy nuclides become exponentially longer-lived as they approach the predicted location of the island. Oganesson is radioactive, decaying via alpha decay and spontaneous fission, with a half-life that appears to be less than a millisecond. Nonetheless, this is still longer than some predicted values.

Calculations using a quantum-tunneling model predict the existence of several heavier isotopes of oganesson with alpha-decay half-lives close to 1 ms.

Theoretical calculations done on the synthetic pathways for, and the half-life of, other isotopes have shown that some could be slightly more stable than the synthesized isotope Og, most likely Og, Og, Og, Og, Og, Og and Og (the last reaching the N = 184 shell closure). Of these, Og might provide the best chances for obtaining longer-lived nuclei, and thus might become the focus of future work with this element. Some isotopes with many more neutrons, such as some located around Og, could also provide longer-lived nuclei.

In a quantum-tunneling model, the alpha decay half-life of Og was predicted to be 0.66 +0.23 −0.18 ms with the experimental Q-value published in 2004. Calculation with theoretical Q-values from the macroscopic-microscopic model of Muntian–Hofman–Patyk–Sobiczewski gives somewhat lower but comparable results.

### Calculated atomic and physical properties

Oganesson is a member of group 18, the zero- valence elements. The members of this group are usually inert to most common chemical reactions (for example, combustion) because the outer valence shell is completely filled with eight electrons. This produces a stable, minimum energy configuration in which the outer electrons are tightly bound. It is thought that similarly, oganesson has a closed outer valence shell in which its valence electrons are arranged in a 7s 7p configuration.

Consequently, some expect oganesson to have similar physical and chemical properties to other members of its group, most closely resembling the noble gas above it in the periodic table, radon. Following the periodic trend, oganesson would be expected to be slightly more reactive than radon. However, theoretical calculations have shown that it could be significantly more reactive. In addition to being far more reactive than radon, oganesson may be even more reactive than the elements flerovium and copernicium, which are heavier homologs of the more chemically active elements lead and mercury, respectively. The reason for the possible enhancement of the chemical activity of oganesson relative to radon is an energetic destabilization and a radial expansion of the last occupied 7p- subshell. More precisely, considerable spin–orbit interactions between the 7p electrons and the inert 7s electrons effectively lead to a second valence shell closing at flerovium, and a significant decrease in stabilization of the closed shell of oganesson. It has also been calculated that oganesson, unlike the other noble gases, binds an electron with release of energy, or in other words, it exhibits positive electron affinity, due to the relativistically stabilized 8s energy level and the destabilized 7p level, whereas copernicium and flerovium are predicted to have no electron affinity. Nevertheless, quantum electrodynamic corrections have been shown to be quite significant in reducing this affinity by decreasing the binding in the anion Og by 9%, thus confirming the importance of these corrections in superheavy elements. 2022 calculations expect the electron affinity of oganesson to be 0.080(6) eV.

Monte Carlo simulations of oganesson's molecular dynamics predict it has a melting point of 325 ± 15 K and a boiling point of 450 ± 10 K due to relativistic effects (if these effects are ignored, oganesson would melt at ≈ 220 K). Thus oganesson would probably be a solid rather than a gas under standard conditions, though still with a rather low melting point.

Oganesson is expected to have an extremely broad polarizability, almost double that of radon. Because of its tremendous polarizability, oganesson is expected to have an anomalously low first ionization energy of about 860 kJ/mol, similar to that of cadmium and less than those of iridium, platinum, and gold. This is significantly smaller than the values predicted for darmstadtium, roentgenium, and copernicium, although it is greater than that predicted for flerovium. Its second ionization energy should be around 1560 kJ/mol. Even the shell structure in the nucleus and electron cloud of oganesson is strongly impacted by relativistic effects: the valence and core electron subshells in oganesson are expected to be "smeared out" in a homogeneous Fermi gas of electrons, unlike those of the "less relativistic" radon and xenon (although there is some incipient delocalisation in radon), due to the very strong spin–orbit splitting of the 7p orbital in oganesson. A similar effect for nucleons, particularly neutrons, is incipient in the closed-neutron-shell nucleus Og and is strongly in force at the hypothetical superheavy closed-shell nucleus Uhq, with 164 protons and 308 neutrons. Studies have also predicted that due to increasing electrostatic forces, oganesson may have a semibubble structure in proton density, having few protons at the center of its nucleus. Moreover, spin–orbit effects may cause bulk oganesson to be a semiconductor, with a band gap of 1.5 ± 0.6 eV predicted. All the lighter noble gases are insulators instead: for example, the band gap of bulk radon is expected to be 7.1 ± 0.5 eV.

### Predicted compounds

The only confirmed isotope of oganesson, Og, has much too short a half-life to be chemically investigated experimentally. Therefore, no compounds of oganesson have been synthesized yet. Nevertheless, calculations on theoretical compounds have been performed since 1964. It is expected that if the ionization energy of the element is high enough, it will be difficult to oxidize and therefore, the most common oxidation state would be 0 (as for the noble gases); nevertheless, this appears not to be the case.

Calculations on the diatomic molecule Og showed a bonding interaction roughly equivalent to that calculated for Hg, and a dissociation energy of 6 kJ/mol, roughly 4 times of that of Rn. Most strikingly, it was calculated to have a bond length shorter than in Rn by 0.16 Å, which would be indicative of a significant bonding interaction. On the other hand, the compound OgH exhibits a dissociation energy (in other words proton affinity of oganesson) that is smaller than that of RnH.

The bonding between oganesson and hydrogen in OgH is predicted to be very weak and can be regarded as a pure van der Waals interaction rather than a true chemical bond. On the other hand, with highly electronegative elements, oganesson seems to form more stable compounds than for example copernicium or flerovium. The stable oxidation states +2 and +4 have been predicted to exist in the fluorides OgF and OgF. The +6 state would be less stable due to the strong binding of the 7p subshell. This is a result of the same spin–orbit interactions that make oganesson unusually reactive. For example, it was shown that the reaction of oganesson with F to form the compound OgF would release an energy of 106 kcal/mol of which about 46 kcal/mol come from these interactions. For comparison, the spin–orbit interaction for the similar molecule RnF is about 10 kcal/mol out of a formation energy of 49 kcal/mol. The same interaction stabilizes the tetrahedral T configuration for OgF, as distinct from the square planar D one of XeF, which RnF is also expected to have; this is because OgF is expected to have two inert electron pairs (7s and 7p). As such, OgF is expected to be unbound, continuing an expected trend in the destabilisation of the +6 oxidation state (RnF is likewise expected to be much less stable than XeF). The Og–F bond will most probably be ionic rather than covalent, rendering the oganesson fluorides non-volatile. OgF is predicted to be partially ionic due to oganesson's high electropositivity. Oganesson is predicted to be sufficiently electropositive to form an Og–Cl bond with chlorine.

A compound of oganesson and tennessine, OgTs, has been predicted to be potentially stable chemically.

## Abstract

Kyle MacLean Kirkwood (born October 19, 1998) is an American auto racing driver. He currently drives the No. 27 for Andretti Autosport in the IndyCar Series.

## Career

### Karting

Born in Jupiter, Kirkwood began karting at a young age, often competing alongside fellow Jupiter native Oliver Askew. Throughout his karting career, he amassed multiple titles, including the AM Engines Formula Tag Junior championship in 2012, the SKUSA SuperNationals XVII - S5 Junior championship in 2013 and back-to-back wins at the Florida Winter Tour in 2015 and 2016.

### Lower formula

In 2015, Kirkwood made his single-seater debut in the F1600 Championship with Chastain Motorsports. There he took victory in the season opener at Road Atlanta and contested a further six rounds to finish sixteenth.

Following his performance in Formula 4 United States, Kirkwood returned to the Formula Ford scene in 2016 to represent Team USA in the Formula Ford Festival and Walter Hayes Trophy event, finishing seventh and fourth overall in both respective events.

In 2016, Kirkwood joined the inaugural Formula 4 United States Championship with Primus Racing, which saw him claim a win at Mid-Ohio and finish third in the standings overall. In September 2016, Kirkwood was awarded with the Team USA scholarship.

After competing with them in pre-season testing at NOLA, Kirkwood returned to the championship the following year, switching to newcomers Cape Motorsports. He achieved nine victories, including back-to-back hat-tricks at Indianapolis and Motorsport Park, wrapping up the title in the Formula One supporting season finale at the Circuit of the Americas. During the season, Kirkwood was once again selected as a candidate for the Team USA scholarship.

### International Formula 3

In August 2018, Kirkwood joined Abel Motorsports to contest the inaugural season of F3 Americas. The season saw Kirkwood claim fifteen of the seventeen race victories on offer and seal his third consecutive championship at NOLA with a round to spare.

The following year, Kirkwood made a one-off appearance with RP Motorsport in the season finale of the Euroformula Open Championship at Monza, which saw him take a best-placed finish of sixth in race two.

### Formula E

In February 2020, Kirkwood was announced to be partaking in the rookie test at Marrakesh with BMW i Andretti Motorsport.

### Road to Indy

In December 2016, Kirkwood partook in the Mazda Road to Indy Shootout, but lost out on the scholarship to Askew.

#### USF2000

In 2017, Kirkwood partook in the Chris Griffis Memorial Test with Swan-RJB Motorsports. In February 2018, he reunited with Cape Motorsports to contest the 2018 championship. In only his rookie season, Kirkwood dominated proceedings, taking twelve of the fourteen victories on offer and sealing his second title in a year at Mid-Ohio and equalling J. R. Hildebrand 's record of wins across a season.

#### Indy Pro 2000

Kirkwood graduated to the championship in 2019, selecting RP Motorsport Racing as his team. After faltering in earlier rounds, Kirkwood took his maiden victories in both races at Road America. From the second race at Toronto onwards, Kirkwood dominated the season and won his fourth consecutive title at the season finale in Laguna Seca despite being taken out by Danial Frost.

#### Indy Lights

In December 2019, Kirkwood partook in the post-season test at Sebring with reigning champions Andretti Autosport. The following month, Andretti confirmed Kirkwood would race with them for the 2020 season, only for that year's running of the championship to be canceled due to the COVID-19 pandemic.

Kirkwood won the 2021 Indy Lights Championship for Andretti Autosport. In doing so, he became the first driver to win a championship in every Road to Indy series.

### IndyCar

Throughout 2021, Kirkwood was viewed with significant interest by different teams in the IndyCar Series paddock. Andretti Autosport owner Michael Andretti stated he intended to keep Kirkwood in the Andretti Autosport stable and reiterated this after Kirkwood won the Indy Lights championship. Andretti stated that he was considering moving Kirkwood to Formula E if a seat did not open up in IndyCar.

As part of winning the Indy Lights championship, Kirkwood was guaranteed to compete in three IndyCar races in 2022, including the 2022 Indianapolis 500.

On November 10, 2021, it was announced that Kirkwood would drive the No. 14 entry full-time for A. J. Foyt Enterprises during the 2022 IndyCar Series season. He had a best finish of 10th at Long Beach, and ranked 24th in points.

On June 1, 2022, Kirkwood and Andretti Autosport announced he would return to the Andretti stable for the 2023 season to replace the departing Alexander Rossi. Kirkwood took his first IndyCar win at the 2023 Acura Grand Prix of Long Beach. Kirkwood took a second win at the 2023 Big Machine Music City Grand Prix.

### Sports car racing

With the 2020 Indy Lights season cancelled due to the COVID-19 pandemic, Kirkwood drove four races in the I MSA Prototype Challenge and also joined AIM Vasser Sullivan Racing for a limited GTD schedule.
