Complex, in chemistry, a substance, either an ion or an electrically neutral molecule, formed by the union of simpler substances (as compounds or ions) and held together by forces that are chemical (i.e., dependent on specific properties of particular atomic structures) rather than physical.
Then, what is a complex metal?
In chemistry, a coordination complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.
What is a molecular complex?
A complex is a molecular entity formed by loose association involving two or more component molecular entities (ionic or uncharged), or the corresponding chemical species. The bonding between the components is normally weaker than in a covalent bond.
What does it mean when you have a complex?
an emotional problem caused by unreasonable fears or worries. have/develop a complex about something: I used to have a complex about being in crowds. give someone a complex: If you keep telling her she’s clumsy, you’ll give her a complex.
What is a complex reaction in chemistry?
Complex reaction mechanisms can consist of a number of electron transfer steps, with some chemical steps preceding or succeeding the electron transfer steps or taking place in between them. Most organic electrochemical reactions are complex, involving large numbers of electrons in the overall reaction.
What is meant by simple substance?
A simple substance is any sample of one of the known elements found in the Periodic Table of the Elements. Elements are made up of atoms of the same kind, and cannot be decomposed by any chemical means into any other simpler elements.
What is a clause in a complex sentence?
Complex sentences contain an independent clause and at least one dependent clause. An independent clause has the ability to stand alone as a sentence. It always makes a complete thought. A dependent clause cannot stand alone, even though it has a subject and a verb.
What is a example of substance?
Examples of substances: Iron is an element and hence is also a substance. Methane is a compound and hence is also a substance. Examples of non-substances: Salt water is not a substance. It is a mixture of two substances – sodium chloride and water.
Can an atom be broken up?
Essentially, it is the smallest possible part of an element that still remains the element. Under normal circumstances an atom can be broken down into any smaller particles, but we humans, have devised ways to break the atom apart. That is the entire basis of the atom bomb, particle colliders, and quarks.
Can a molecule be broken down?
Note that an element: consists of only one kind of atom, cannot be broken down into a simpler type of matter by either physical or chemical means, and. can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen).
Can an element be broken down physically?
Elements – simplest form of pure substance. They cannot be broken into anything else by physical or chemical means. Compounds – pure substances that are the unions of two or more elements. They can be broken into simpler substances by chemical means.
Can an element be broken down?
All matter is composed of one or more substances (elements and/or compounds); compounds can be broken down into simpler substances: elements cannot be broken down chemically. II. All matter is composed of tiny particles, called atoms. A. Atoms of different elements are different.
Can a mixture be broken down?
Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.
What are the seven states of matter?
The seven states of matter explained
Solid, liquid and gas – these are the physical states most people know.
Bose-Einstein condensate: a state of matter that occurs very close to absolute zero.
Quark-gluon plasma: the state of matter with the highest energy level.
Can a mixture be physically separated?
SEPARATING MIXTURES. The substances in a mixture are separated by the differences in their physical properties, such as their particle size. The more different the properties are, the easier it is to separate the substances. Tea leaves do not dissolve in water, so you can use a strainer to FILTER them.
What is crystallisation used to separate?
Explanation: Crystallization is the slow precipitation of crystals from a saturated solution. When it is used to purify an impure solid, the process is often called fractional crystallization or recrystallization. You heat a sample of the impure compound with a suitable solvent, often at its boiling point.
How compounds can be separated?
Each substance in the mixture keeps its own properties. The compound has properties different from the elements it contains. Each substance is easily separated from the mixture. It can only be separated into its elements using chemical reactions.
What is a compound made up of?
The elements in any compound are always present in fixed ratios. Example 1: Pure water is a compound made from two elements – hydrogen and oxygen. The ratio of hydrogen to oxygen in water is always 2:1. Each molecule of water contains two hydrogen atoms bonded to a single oxygen atom.
What is the difference between a molecule and a compound?
A molecule is formed when two or more atoms of an element chemically join together. If the types of atoms are different from each other, a compound is formed. Not all molecules are compounds, since some molecules, such as hydrogen gas or ozone, consist only of one element or type of atom.
What is a molecule of a compound?
Molecules have molecular bonds. Nitrogen gas (N2) is a molecule because the bond between the nitrogen atoms is a molecular bond. Water (H2O) is a molecular compound because it is a substance made from more than one kind of element that is held together with molecular bonds. I am not clear on what a molecule is.
Is Gold is a compound?
Strictly speaking, gold metal is the element Au on the periodic table, hence it is an element. Furthermore, it is generally very unreactive and is unlikely to form compounds easily, hence the “gold” you encounter is usually always elemental gold(or its alloy). It is an element, Au in periodic table.
What is a complex personality?
Answered in order the questions are asked: Complex person is someone who is difficult to understand/comprehend as an individual due to their personality or lifestyle. However this does not necessarily mean complexity is bad.
What does it mean when someone says you have a God complex?
A god complex is an unshakable belief characterized by consistently inflated feelings of personal ability, privilege, or infallibility.
What is a personality complex?
A personality disorder is a type of mental disorder in which you have a rigid and unhealthy pattern of thinking, functioning and behaving. A person with a personality disorder has trouble perceiving and relating to situations and people. Personality disorders usually begin in the teenage years or early adulthood.
