The number of electrons in the outer energy level of aluminum?

It depends on what elements are involved. Iron has two electrons in its outer shell, Lead has four. While in a metal, the outer electrons flow freely over the surface of the solid, there is no net loss or gain of electrons, the atoms do not become ionized, and are considered to still have their original number of electrons.
