Answer:
From the chemical formula of the compound aluminium oxide Al 2 O 3, the valency of aluminium can be determined. Since we know that the valency of oxygen is 2, and there are 3 oxygen atoms, this gives a total value 6 for the valencies of the oxygen atoms, which has to be matched by the 2 atoms of aluminium. Hence the valency of aluminium is 3.
