>> [Ar] 3d6 4s2

Thus, following the rules on how to fill the orbitals, the electronic configuration of iron (for example) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6 , and it is abbreviated form [Ar] 4s2 3d6. However, I has not been easy to find the explanation on why in any periodic table it is written as [Ar] 3d6 4s2 instead.

hope it helps❤❤
