Respuesta :

Al as it is in group 13
electronic figuration would be
[Ne] 3s2, 3p1
simple electronic configuration is
2:8:3

The Answer is Al.

Valence electron:-

It is an outer shell electron with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

Electronic configuration of Al:-

[tex][Ne] 3s^{2} , 3p^{1}[/tex]

So, the valence electrons are 3 in the case of Al.

Hence, the correct option is Al.
