Because Al has 1 more proton, so the atomic radius is smaller. A greater electrostatic force of attraction between the electron shells and nucleus. Also Al is a smaller atom than Mg.

exactly how is it a smaller atom? I understand its a smaller Ion, but atom?

It has a higher nuclear charge due to more protons so the attraction of the outer electrons and the positive nucleus pulls in the atom. Almost like squishing
