The oxidation number for 'O2' is zero(0).
However, when calculating oxidation numbers in compounds containing oxygen, then the oxygen is used as a standard at '-2'.
So as an example using potassium permanganate (KMnO4), what is the oxidation number of manganese (Mn).
In solution this dissolves producing the permanganate ion (MnO4^(-).
Note the charge on the ion is '-1'.
Since there are 4 oxygens present , then the oxidation of the oxygen moiety is 4 X -2 = -8 .
So creating a little sum
Mn + -8(oxygen moiety) = -1 (overall charge on the ion).
Mn + -8 = -1
Add '8' to both sides
Mn = (+)7 is the oxidation number of manganese.
So the formula could be written as KMn(VII)O4 . (Note the Roman numerals for oxidation number).

Does Oxygen have the same oxidation number in ozone O3 and in oxygen O2?
No, the oxidation number of oxygen in ozone (O3) is -2/3, while in oxygen (O2) it is 0. In ozone, one oxygen atom has an oxidation number of -1 and the other two have an oxidation number of 0, resulting in an average oxidation number of -2/3.

WHAT IS THE OXIDATION NUMBER OF OXYGEN AToms in o22?
The oxidation number of oxygen atoms in O2 is 0 because oxygen generally exhibits a zero oxidation state in elemental form.
What is the oxidation number of oxygen in O2PtF6?
In the compound O2PtF6, oxygen has an oxidation number of -1. This is because fluorine is more electronegative than oxygen and is assigned an oxidation number of -1. Since there are two fluorine atoms in the compound, the total oxidation number contributed by fluorine is -2. Therefore, the oxidation number of oxygen must be -1 to balance the overall charge of the compound, which is 0.
What is the oxidation number for element O?
The oxidation number of O in any elemental form (e.g. O2, O3) is zero. Typically in chemical compounds the oxidation number of O is -2 (oxide ion)
Oxidation number of Cr in CrO5?
6. This is because it is a peroxide, with a structure Cr(O)(O2)2, where the nominal ligands are O2- (-2 ox.number in oxides) and O22- (-1 ox.number in peroxides) which gives the Cr an oxidation number of +6. It is sometimes called Chromium(VI) oxide peroxide.
What is the oxidation number of MnO2?
The oxidation number of Mn in MnO2 is +4. This is determined by assigning oxygen an oxidation number of -2, and knowing that the overall charge of the compound is zero.
Oxidation number of no3?
If you are referring to the nitrate ion, NO3-, the oxidation number of oxygen would be O2- and nitrogen would be N5+. If you are talking about nitrogen trioxide NO3, the oxidation number of oxygen would be O2- and nitrogen would be N6+. Edit: Nitrogen trioxide does not exist in its free state.
