Q:

How many valence electrons does gallium have?

A:

Quick Answer

Gallium has three valence electrons. One can find this by looking at the electron configuration, which is Ga:[Ar] 4s2 3d10 4p1. In a chemical reaction, one can lose the electrons in the 4s and 4p subshell, and the total number of electrons in these subshells is three.
