Answer:

Oxidation number of Al in Al2O3

Each oxygen has -2 oxidation number

So 3 oxygens have -6 oxidation number cumulatively.

In a neutral compound, the sum of oxidation numbers of all elements = 0

So 2 Al atoms have +6 oxidation number.

1 Al atom therefore has + 3 oxidation number.

Oxidation Number of Al is +3 in Al2O3
