∙ 12y agoMagnesium has 2 electrons in its outer most shell and these 2 are the valency electrons.
The valency of nitrogen is 3
The # of Valance electrons in the oxygen famly is 6
12; and that would be a magnesium atom.
A magnesium atom would need 6 electrons to complete its highest occupied electron shell. In practice, a magnesium atom almost never does this, because the energy required would be too great. Instead, the magnesium atom transfers 2 electrons to one or more atom that are more electronegative than magnesium and thereby forms a magnesium ion with an electrical charge of +2. In this ion, the highest occupied shell of a magnesium atom is completely empty of electrons.
