Answer:
Thus, removal of electrons from aluminium requires higher energy than sodium i.e. ionization energy of aluminium is higher than sodium. This makes sodium more metallic than aluminium. Also, upon losing one electron sodium will gain a stable nearest noble gas configuration thus it will lose electrons readily.

We can see that sodium and aluminium are in the same period (3) and electrons in aluminium are added in the same shell as that of sodium. Thus, the effective nuclear charge is more on aluminium than sodium and thus aluminium has a smaller size. This makes sodium more metallic than aluminium.
