What is the oxidation state of an individual bromine atom in NaBrO 3?b. If you are talking about the ion itself, I would write it as AlCl4^-If you are talking about drawing the Lewis structure and counting formal charge on each atom; if you count them you will see that each Cl is zero formal charge and the Al has a formal charge of -1. Determine the oxidation state of Cl in each species. O = -2. How does AlCl4- formed then? AlCl-43.) Identify the oxidation state of Cl in Cl,0,. For example, Cl – has an oxidation state of -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.
