3s and 3p

Explanation:

From the question given above, the following data were obtained:

Electronic configuration =>

1s² 2s²2p⁶ 3s²3p⁴

Location of valence electron =?

From the electronic configuration given above, we can see clearly that the atom has three (3) shells.

Valence electron(s) are located at the outer most shell of an atom.

The outer most shell of the atom above is 3s and 3p.

Therefore, 3s and 3p will contain the valence electron(s)
