If an atom has 2 valence electrons it will form an ion with what charge?

Mg most commonly forms a 2+ ion. This is because Mg has two valence electrons and it would like to get rid of those two ions to obey the octet rule. Fluorine has seven valence electrons and usually forms the F – ion because it gains one electron to satisfy the octet rule.
