The ground state electron configuration of Fe is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶

From the question,

We are to write the ground state electronic configuration of Fe (Iron)

First, let us define what is meant by ground state electronic configuration.

The ground state electron configuration is the arrangement of electrons around the nucleus of an atom with lower energy levels.

Now,

The ground state electronic configuration of Fe is

Fe - 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶

OR

It can also be written as

Fe - [Ar] 3d⁶ 4s²

NOTE: [Ar] represents the electron configuration of argon

Hence, the ground state electron configuration of Fe is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶
