Oxidation number of Hydrogen = 1Oxidation number of Oxygen = (-2) Total charge on atom = 0Now, to find N in HNO3N 1 (-2) = 0N 1 = 6So N = 5 Oxidation number of Nitrogen in Nitric acid is 5 0. reply. Because ammonia is neutral, the individual oxidation numbers must sum to zero. (Recall that H usually has an oxidation number of +1.) NH3, Ammonia is a neutral compound as the individual oxidation numbers elements that make up the compound NH3 are Nitrogen (N) and Hydrogen (H) sum to zero. When it comes to calculation the oxidation number of N in KNO3, we can make a small equation. Thus, the oxidation number for Nitrogen is -3. a) oxidation number of hydrogen is +1 in all compounds except hydrides. Most polyatomic ions are negative, but this is one of the few that is positive.
