The oxidation number for Ba in BaO2 is +2, as the oxidation number for oxygen is typically -2. Since there are two oxygen atoms in BaO2, the overall charge must be balanced out by Ba having a +2 oxidation number.
The oxidation number of barium in BaO2 is 2.
In assigning formal oxidation states it is necessary to consider the bonding present amongst the species involved. FeS2 was one of the earliest crystal structures solved by X-ray diffraction methods and the simple cubic crystals clearly show sulphur-sulphur bonding within [S-S]2- units. These can be viewed as derived from hydrogen disulphide, H2S2 (cf. hydrogen peroxide, H2O2). Thus FeS2 would be better described as iron persulphide rather than disulphide. In considering the material as Fe2+S22− it is clear that the oxidation state of Fe is +2 while that of each S moeity is -1. A similar problem can be posed via barium peroxide, BaO2, where the oxidation state of barium must be +2 (metal in Gp 2). What is the oxidation state of oxygen in BaO2 ?
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
