In KMnO4, Mn has an oxidation number of +7, KNO2 has N with an oxidation number of +3, and H2SO4 has S with an oxidation number of +6. In MnSO4, Mn has an oxidation number of +2, H2O has O with an oxidation number of -2, KNO3 has N with an oxidation number of +5, and K2SO4 has S with an oxidation number of +6.
When calculating oxidation numbers, use '-2' for oxygen as a standard. It does vary in some oxygen molecules, but '-2' is a good starting point. So in KNO3 The oxygen moiety is 3 x -2 = -6 Potassium(K) is always '+1' because it only loses one electron . Hence the nitrgen os +1 + N - 6 = 0 N- 5 = 0 N = +5 (oxidation state) NB For neutrally charged molecule, the sum of the oxidation number is always 'zero'(0).
In KNO3 the oxidation number of potassium (K) is 1+, for nitrogen (N) it is 5+, and for each oxygen (O) it is 2-
The oxidation number of N in NCl3 is +3. This is because the oxidation number of Cl is -1, and there are three Cl atoms in NCl3, so the overall charge must be balanced by N having an oxidation number of +3.
The oxidation number of nitrogen (N) in nitric oxide (NO) is +2.

The oxidation number of nitrogen (N) in nitric oxide (NO) is +2.
The oxidation number for N in NH2CONH2 is -3. This is because hydrogen atoms have an oxidation number of +1 each, and oxygen atoms have an oxidation number of -2. By using these values, we can calculate the oxidation number for nitrogen.
KNO3 has no oxidation number. However, the individual atoms do each have an oxidation number. Using oxygen as the 'yardstick' at '-2' ; NB There are exceptions this rule. There are 3 oxygens, so the oxygen component has an oxidation of 3 x -2 = -6. So for it to be a neutrally charge molecule the potassium and the nitrogen must sum to +6. Since potassium only loses one electron its oxidation number is '+1'. It follows that nitrogen must be in oxidation state '+5' Summarising;- Potassium(K) = +1 Nitrogen(N) = +5 Oxygen(O) = 3 x -2 = -6 +1+5-6 = 0 NB Nitrogen , like sulphur and phosphorus exhibit various oxidation states. =
Oxidation number of N is +3. Oxidation number of H is -1.
In N2O5, the oxidation number of N (nitrogen) is +5 and the oxidation number of O (oxygen) is -2.
KNO3, or potassium nitrate, has three elements: potassium (K), nitrogen (N), and oxygen (O).
The oxidation number of Na in NaNO3 is +1, the oxidation number of N in NO3 is +5, and the oxidation number of O in NO3 is -2.
The oxidation number of N in NF3 is -3. Each F atom has an oxidation number of -1, and since the overall molecule is neutral, the oxidation numbers must add up to zero, making the oxidation number for N -3.
