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).

What are the oxidation numbers in chromiumIII oxide?
In chromium(III) oxide, the oxidation number of chromium is +3 and the oxidation number of oxygen is -2. This compound has the chemical formula Cr2O3.
What is the oxidation number of H2O2?
The oxidation number for H is +1, and the oxidation number for O is -1.
What is the oxidation number of Cl2O7?
The oxidation number of Cl in Cl2O7 is +7. In Cl2O7, there are 2 Cl atoms with an oxidation number of +14 total, and the oxidation number of O is -2 (since O usually has an oxidation number of -2 in compounds). Use the formula: 2x + 7(-2) = 0, which gives x = +7 for the oxidation number of Cl.
What is the oxidation number of P4O10?
The correct chemical formula should be P2O5 or P4O10 (its dimer) and not P3O10 (as originally asked in the question). The oxidation numbers are -2 for each O +5 for each P
What is the oxidation number of KNO2?
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. =
