The oxidation number for H is +1, and the oxidation number for O is -1.
The oxidation number of O in H2O2 is -1. Each hydrogen atom has an oxidation number of +1, and since the overall molecule has a neutral charge, the oxidation number of oxygen must be -1 for the equation to balance.
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.
Peroxide iion is a anion. O shows the -1 oxidation number.
For the hydrogen atoms the oxidation state is 1+, for the oxygen it is 2-
Hydrogen it depends on the other element if it is part of a compound

O = -2 oxidation state H = +1 oxidation state
Hydrogen it depends on the other element if it is part of a compound
The oxidation number of any free element is 0. So if it is oxygen by itself (e.g., O2) then the oxidation number/state is 0. In its compounds the oxidation number of oxygen is -2. This rule only stands if it isn't a peroxide such as H2O2 or Na2O2, in peroxide cases, the oxygen is -1.
In a peroxide compound, such as hydrogen peroxide (H2O2), oxygen has an oxidation number of -1. This is because the overall charge of the peroxide ion is -2, and since there are two oxygen atoms, each must have an oxidation number of -1 to balance the charge.
2ki + h2o2 = 2koh +i2
Yes, nonmetals can have both positive and negative oxidation numbers depending on the specific compound they are a part of. For example, in compounds such as hydrogen peroxide (H2O2), oxygen can have an oxidation number of -1 whereas in compounds such as O2F2, oxygen can have a positive oxidation number.
The chemical symbol for hydrogen peroxide is H2O2
Hydrogen peroxide may be represented as H2O2 or HO-OH, with contrast to normal oxides the oxidation number of oxygen in peroxide is -1.
