There is also an overall -2 charge on the molecule, meaning that the positive charge due to carbon can only cancel out a charge of -6 due to the oxygen so that the overall molecule … Oxidation results in an increase in oxidation number. NH3 --> Hydrogen gives all its electrons to Nitrogen, therefore Nitrogen's oxidation number here is -3 while the Hydrogens' are +1. O has an oxidation number of -2 which would give an overall charge of -8 due to oxygen in the molecule [C2O4]2- since there are four O's (4*-2 = -8). The oxidation number of a monatomic ion equals the charge of the ion. The answer is (3) HClO. The oxidation number of O is usually –2 (rule 3c). In ClO 3 you have 6- from the 3 oxygens and if you mean the chlorate anion ClO3 - , then Cl will have an oxidation number of 5+. In the Cl2, chlorine has an oxidation number of zero.
