Why does iron have two kinds of valence number?​

Spanish

Bingel [31]2 years ago

Iron has two kinds of valence number because, in order to attain stability it looses it two electrons in the 4 orbital and then has 2 more valencies and since the half filled orbitals are more stable it loses one more electron from d orbital and has +3 valency.
