Question

Give the number of valence electrons for iron. Write out the electronic configuration for the valence electrons. (Give the number of valence electrons in the first box and the electronic configuration of the valence electrons in the second box.)

Answer 1

Explanation:

Iron Valence Electrons = 8

Electronic configuration for valence electrons = [Ar]3d6 4s2.

Hope it helps you.

Good Luck.

Answer 2

electronic configuration of valence electrons 1s²2s²2p⁶3s²3p⁶ 4s²3d⁶or (ar)4s²3d⁶

no.of valence electrons is eight
