Fluorine.
Oxygen has a -2 oxidation number in all compounds except peroxides and compunds with fluorine (+1 or +2)
the most common oxidation number for oxygen is -2.
It is a neutral oxide. Oxygen shows -2 oxidation number.
Elements with positive oxidation number easily combined with those having a negative oxidation number because opposite oxidation number attracts each other.
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.
the answer is -2.Related Information:The oxidation number of oxygen when it appears as an element is 0. The oxidation number in all compounds but peroxides is -2. The oxidation number of oxygen in peroxides is -1.

The oxidation number of oxygen is -2 in most of its compounds
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.

In the compound Co2O3 cobalt has an oxidation number of 3 while oxygen has an oxidation number is -2.
Atomic oxygen has oxidation number 0. Molecular oxygen also has 0 as oxidation number. It would be the same for five oxygen molecules as well.
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
Carbon has an oxidation number of +4 in both carbonate and bicarbonate. Oxygen as usual has an oxidation number of -2, and hydrogen has an oxidation number of +1. Therefore, the ion CO3-2 has six negative charges from oxygen partly balanced by four positive changes from carbon for a net of -2, and HCO3-1 has six negative charges from oxygen partly balanced by one positive from hydrogen and needs for plus four from carbon for an overall value of -1.
Positive oxidation number implies that electrons are generally lost by the element.
