The ion Fe2+ electron configuration is 1s22s22p63s23p63d6

Explanation:

The electron configuration for iron, Fe is 1s22s22p63s23p63d64s2

The orbital filling order for Fe is 1s22s22p63s23p64s23d6

Iron does not occur as Fe2 in nature. It is not a diatomic element.

The ion Fe2+ electron configuration is 1s22s22p63s23p63d6.

It is missing the two valence electrons in the 4s2 orbital. This makes the ion a cation, an ion that is positively charged because it has lost valence electrons.
