+1 for K
-2 for each O
+5 for N
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 NO, nitrogen oxide, is +3.

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 NO, nitrogen oxide, is +3.
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. =
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.
Oxidation number of N is +3. Oxidation number of H is -1.
KNO3 has 3 elements which are potassium, Nitrogen and Oxygen.
In N2O5, the oxidation number of N (nitrogen) is +5 and the oxidation number of O (oxygen) is -2.
+1 for Na +5 for N -2 for each O
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.
