The oxidation number for Ga in Ga2O3 is +3.
If the question is Ga2, then it is equivalent to Ga and the oxidation number for any element is zero.If the question is Ga2+, then the oxidation number is +2.
0 in elemental form, +3 in compounds
oxidation number of I is -1. oxidation number of F is +1.
Ionic gallium has a 3+ (Ga3+) charge, and the Oxide ion has a 2- (O2-) charge. Therefore, the chemical formula (the combination of the ions to form an ionic compound) is Ga2O3, which balances the charges.
Zn has oxidation number +2; S has oxidation number -2
