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).

What is the oxidation number of o in o2?
The oxidation number is 0. The sum of all oxidation number in a molecule that has not charge is always 0. If it has a charge (ion negative or positive) then the sum must be equal to the charge number.
What is oxidation number for Na in NaOH?
The oxidation number is +1. (Oxidation number for an ion is the ionic charge)
What is the oxidation number of MnO2?
O2 is -2 so Mn is +4
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.
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.

When the H2O2 serves as an oxidizing agent which product might be formed from it O2 or H2O?
When H2O2 acts as an oxidizing agent, the H2O2 must be reduced. Therefore, the product from it will be water, in which oxygen has an oxidation number of -2, whereas in H2O2 has an oxidation number of -1 and in O2 the oxygen has an oxidation number of 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)
What kind of reaction is 2H2O2 2H2O plus O2?
2H2O2 <-> H2O + O2 the oxidation number of each O in H2O2 is -1 the oxidation number in H2O is -2 the oxidation number in O2 is zero. The average oxidation number of oxygen atoms on both sides of the equation. is the same. So overall the net change to oxygen is zero one is reduced two are oxidised. Looked at from the viewpoint of the oxygen atoms in O2 they started off with oxidation number of -1 and have ended up with 0, so they have been oxidised. (oxidation is loss of electrons, and therefore an increase in oxidation number.)
What is the oxidation number of titanium?
The oxidation number of any element by itself is 0.
What is the oxidation number of oxygen in O2PtF6?
The structure of O2PtF6 is known and there is an O2 unit. The O2 is best formulated as O2+ ( dioxygenyl) and the oxidation number of each O atom is +1/2. (+0.5). This is an interesting compound PtF6 is a very stong oxidising agent.
In this equation 2mno2 plus 2k2co3 plus o2--2kmno4 plus CO2 what atom increases in oxidation number?
Mn increase in oxidation number from +4 to +7.
What is the oxidation number of SO2?
Oxidation state of O is -2.Oxidation state of S is +4.
