Why is the formula of aluminium oxide Al2O3?
Since the overall charge of a compound must always be equal to zero (neutral), we need 2 aluminum atoms and 3 oxygen atoms in order to balance out the charge and make the compound neutral. This means that the chemical formula for aluminum oxide is simply Al2 O3. That's 2 aluminum atoms for every 3 oxygen atoms.
