Octet Exceptions: Al

Why can't Al have a full octet?

Al doesn't achieve a full octet because it only has 3 valence electrons and would need to gain five electrons to have a full valence shell which is difficult.

I think Al is capable of gaining 5 electrons to gain Octet, but it is also capable of forming only three bonds and thus has only 6 valence electrons, which is very similar to the bonding property of Boron.
