Aluminum has 13 electrons in a neutral atom. The 1S2, 2S2 and 2P6 shells are full, and so is the 3S2. The 3P1 shell has one electron in it (in Al's neutral atom) and that gives aluminum one lone valence electron and two semi-valence electrons which can be loaned out.
Sodium has 11 electrons 2 in its its first orbital (1s2) 6 in the second(2p6) and 1 in the outer orbital (2s1) But Sodium is not stable with one lone electron spinning around, so it will always give it up whenever possible, hence it will always be one electron short- giving the element a positive charge.
