We need 2 atoms of N for every 3 atoms of As. 1. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component. To find the correct oxidation state of N in Ca(NO3)2 (Calcium nitrate), and each element in the compound, we use a few rules and some simple math.First, since the Ca(NO3)2 doesn’t have an overall charge (like NO3- or H3O+) we could say that the total of the oxidation numbers for Ca(NO3)2 will be zero since it is a neutral compound.We write the oxidation number (O.N.)
