The oxidation number of cobalt in Co2O3 is +3, and the oxidation number of oxygen is -2. This is based on the rules for assigning oxidation numbers, where the overall charge of the compound must equal zero.
Cobalt has an oxidation number of 3 (III) in the compound Co2O3.
In the compound Co2O3, cobalt's oxidation number is +3. Each oxygen atom has an oxidation number of -2, and since the compound is neutral, the sum of the oxidation numbers must equal zero, leading to cobalt having an oxidation number of +3.
In the compound Co2O3 cobalt has an oxidation number of 3 while oxygen has an oxidation number is -2.
Co2(CO3)3The chemical formula of cobalt(III) carbonate [not cobalt(111)] is Co2(CO3)3.
Carbon trioxide, also known as carbon sesquioxide, is the chemical name for Co2O3. It is an unstable oxide of carbon and has limited practical applications.

Carbon trioxide, also known as carbon sesquioxide, is the chemical name for Co2O3. It is an unstable oxide of carbon and has limited practical applications.
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.
Silicon's oxidation number is +4.Oxygen's oxidation number is -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.
