EDIT:- RE: the below answer. You are correct insomuchas Cr and Cu do not fit the general pattern of transition metal electronic configurations, and therefore, exist as [Ar]4s1,3d5 and [Ar]4s1,3d10 respectively. However, Fe(II) is not Cr and does not exist as Cr (although having the same number of electrons). It is not an exception. The u/Ar_3d6_4s2 community on Reddit. Reddit gives you the best of the internet in one place.

after, which puts you at Mg. For the latter, you look at Argon, count 2 "4s" electrons then 6 "3d" electrons. and you'll end up on Fe. What is the Electronic configuration of iron is [Ar] 3d6 4s2. Irons peculiar crystalline structure and electronic configuration make naturally attractive to metals.

Answer and Explanation: The ground state shorthand notation for iron (Fe) is [Ar] 4s2, 3d6. One may also ask, what is fe2+ and fe3+? Difference about Fe2+and Fe3+ is the number of electrons, which in turn results in different properties. Fe2+, aka ferrous, is pale green and turns violet when added to water.
