The oxidation number of diatomic and uncombined elements is zero. Work out the overall charge of the complex by comparing with the charge on the counter ions. To find the correct oxidation state of Ni in Ni(NO3)2, Nickel (II) nitrate, and each element in the compound, we use a few rules and some simple math. The N O X 3 X − ion cannot be depicted using a single Lewis structure. Videos. Nitrate has a -1 charge, so AgNO3 has Ag in the +1 oxidation state, and Cu(NO3)2 has copper in the +2 oxidation state. 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. Oxygen actually does take two electrons. The oxidation state of an uncombined element is zero. For example, in [Co(NH3)5Cl]CL2, we know that Cl has a -1 charge, and there are two of them, so to make the compound neutral the charge on the complex part must be 2+. The oxidation number method is a way of keeping track of electrons when balancing redox equations. Simonizer1218.
