Two electrons from each element are shared; the total is four electrons.
Six electrons (three pairs) are shared between two atoms that form a triple bond.
Al2O3, each formula unit would have 6 shared electrons. Al wants 3 electrons per atom and O can give 2 electrons per atom.
In a covalent bond electrons are shared between two electrons.
