Each aluminium ion should have a charge of +2, because the sum of oxidation numbers must be zero.

The uncharged aluminium atom must lose two electrons to become an ion with +2 charge.
what has to happen to an uncharged aluminum atom so that it will bond with oxygen?

It has to lose electrons to become positively charged, so it can attract a negatively charged oxygen ion
