Iron is the fourth most abundant element on earth and one of the most common elements in our bodies. Iron has a valence electron configuration of 2, 8, 18, or 22 depending on its location within an atom. The first step to finding out how many valence electrons iron has is to find out what type of orbital it occupies – s, p, d, or f. For example, if the iron was found in a 3d orbital then it would have 18 valence electrons because that’s the limit for 3d orbitals.
A second step is to find out the number of electrons in its outermost orbital. Iron has a valence electron configuration of 18 so the next thing you need to do is count how many electrons are present in iron’s highest energy level. You can either guess (based on what you know about elements and their properties) or use something called QMLEO which stands for Quality Modeling Lab Electron Orbital Evaluator Online, which relies on quantum mechanics calculations to determine electron densities and probabilities.
What does this have to do with anything? Well, one answer is that it affects our health because these valance electrons play an important role in oxidation reaction all things related to rust! But also…iron may be useful as a battery!
How Electron Configuration Affects Iron’s Valence Electrons: How many valence electrons does iron have? A full understanding of the electron configuration for iron is necessary in order to find out how many valance electrons it has. The total number of valence electrons that an element can hold is based on what shell level they occupy, and with 18 protons in its nucleus, irons highest energy level contains eight shells which comprise three sub-shell levels each; two (or a double) filled lower energy levels followed by six (or four empty ) higher ones. This means that there are 24 available orbitals – 12 orbitals at the innermost shell level and 12 more at the next one up. For this reason, iron has a total of 24 valence electrons.
What Is Iron’s Valency?
How many valance electrons are present in iron? The number of outermost orbitals determines the element’s valence, and for most elements, this is an even number because they have only one filled inner orbital shell. However, there are exceptions to this rule such as hydrogen which has two (or single) occupied orbitals at its lowest level and six more available ones on top, or carbon that also has four empty orbitals at its second-lowest energy level. In these cases – atoms with odd numbers of electron orbits – we say it holds “odd” rather than the usual “even” amount of valence electrons; so what does that mean for iron?
What Is Iron’s Electron Configuration? How to find out if the iron has two or eight valence electrons? The number of valence electrons is determined by the electron configuration. For an atom-like Fe, which “happens” to have 26 protons in its nucleus and six neutrons – that can be combined into 24 particles without changing their charge – we need to look at the lowest energy orbitals first: it starts with one shell only occupied (with a total of two electrons), then moves up one level where there are empty outermost orbits capable of holding four more; so this means our answer is eight.
Total Number Of Valency Electrons In Iron = 24 + 12 = 36
Example: Iron has a total of 36 valence electrons.

Iron’s Electron Configuration = Eight Valance Electrons
How To Find Out If Iron Has Two Or Eight Valance Electrons?
The electron configuration is what determines the number of valence electrons that an atom-like Fe, which “happens” to have 26 protons in its nucleus and six neutrons – can hold. It starts with one shell only occupied (with a total of two electrons), then moves up one level where there are empty outermost orbits capable of holding four more; so this means our answer is eight.
So How Many Valence Electrons Does Iron Have? There are many ways for you to find out if the iron has two or eight valence electrons, including the electron configuration method that we just mentioned.
It’s important to find this out because iron is most commonly used in steel production and other applications where it will be reacting with oxygen which needs a certain amount of valence electrons for an oxidation reaction.
As you can see, there are many ways for you to figure out how many valance electrons Iron has; some more complicated than others- but they’re all equally effective at discovering these answers! The best thing about numbers? They always tell us exactly what we need to know!
