How is AL2O3 amphoteric?
I understand that it can act as a base as it contains oxide ions which are strong bases, but how can it act as acid if it doesn't contain any hydrogen atoms to donate as protons? Same for SiO2?

Amphoteric means that it can REACT as either an acid or a base.
Aluminium oxide reacts with acids forming salts
Aluminium oxide reacts with bases forming salts
It is therefore amphoteric
Silicon dioxide is NOT amphoteric. It is an acidic oxide that only reacts with bases forming salts.
