Question

→ How does Fe change to Fe2+?​

Answer 1

Electronic configuration of Fe(Z=26) is

Electronic configuration of Fe(Z=26) is[Ar] 3d64s2

Electronic configuration of Fe(Z=26) is[Ar] 3d64s2 Fe loses 2 electrons from the 4 s orbital and forms Fe2+ ion.

Electronic configuration of Fe(Z=26) is[Ar] 3d64s2 Fe loses 2 electrons from the 4 s orbital and forms Fe2+ ion.Thus it's electronic configuration becomes [Ar] 3d6

hope its helps u

Answer 2

Answer:

Explanation: How is Fe2+ formed?

What is the electron configuration for the Fe2+ ion? It belongs to 4th period. While the electronic configuration of Fe2+is [Ar]3d6. Fe loses 2 electrons from the 4 s orbital and forms ion.
