# Do metals donate or accept electrons?

Feb 7, 2014

In ionic molecules, the metal acts as the positive ion or cation.
In order to take on a positive charge the atom must give away electron. Metals donate electrons.

Magnesium, $1 {s}^{2} 2 {S}^{2} 2 {p}^{6} 3 {s}^{2}$, would greedily give up the two electrons in the 3s orbital to become stable with at $2 {s}^{2} 2 {p}^{6}$.
This would make Magnesium have 12 protons and 10 electrons making it have a +2 charge.
