Question

CHEM HELP !!!!!

Write the electronic configuration of all the electrons for gallium. Then give the electronic configuration of the valence electrons only. (Give the electronic configurations with the orbitals in order of increasing energy.)

Gallium:

Valance Electrons:

Write the electronic configuration of all the electrons for argon. Then give the electronic configuration of the valence electrons only. (Give the electronic configurations with the orbitals in order of increasing energy.)

Argon:

Valance Electrons:

Determine the number of valence electrons and give the electronic configuration of the
valence electrons of gallium.

_____ Valence electrons, valence electron configuration: _____

Explanation / Answer

1)

electronic configuration :

Ga = 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p1

valance electrons = 3

valance electron configuration = 4s2 4p1

2)

Ar = 1s2 2s2 2p6 3s2 3p6

valance electrons = 8

valance electron configuration = 3s2 3p6
