The stable ionic compound formed between aluminum and oxygen is B. Al2O3.
Aluminum has a charge of +3 (Al^3+) and oxygen has a charge of -2 (O^2-). To balance the charges in the compound, two aluminum ions (total charge +6) combine with three oxide ions (total charge -6), resulting in the formula Al2O3.
