The easiest way for a metal to achieve 8 electrons in its outer level is to lose an electron or electrons (depending on what group it's in.) Once it does this, it becomes a cation, or positive ion, meaning that it still has the same number of protons (its elemental identity,) but now has a different number of electrons (less than the atomic number,) and therefore has a positive charge.
