Hi :) Oxygen usually has an oxidation number of -2. You know that the sum of the oxidation numbers in a neutral compound is zero. Thus, in ClO₂, the oxidation number of O is -2 For two O atoms, the total oxidation number is -4. So the oxidation number of Cl must be +4. This makes the sum of all the oxidation numbers equal to zero. Hope I help you. :) To your next question :D
