Fluorine.
Oxygen has a -2 oxidation number in all compounds except peroxides and compunds with fluorine (+1 or +2)
The oxidation number of oxygen when combined with fluorine is -1. Oxygen usually has an oxidation number of -2, but when combined with a more electronegative element like fluorine, oxygen's oxidation number becomes -1.
the most common oxidation number for oxygen is -2.
The oxidation number of hydrogen is +1 when combined with nonmetals, and -1 when combined with metals.
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.
Elemental oxygen 'O2' is in zero oxidation state . However, when oxygen is combined into moledcules, it is usually '-2' , but can be '-1'

Elements with positive oxidation number easily combined with those having a negative oxidation number because opposite oxidation number attracts each other.

Elements with positive oxidation numbers have excess electrons that they can share or transfer with elements having negative oxidation numbers that have electron deficiencies. This transfer or sharing of electrons allows the elements to achieve a more stable electron configuration, forming compounds through the formation of ionic or covalent bonds.
The oxidation number of phosphorus in P4O6 is +3. This is because oxygen typically has an oxidation number of -2, and the overall charge of P4O6 is zero. Therefore, the four phosphorus atoms must have a combined oxidation number of +12 to balance out the -12 from the six oxygen atoms.
The oxidation number of Fe in Fe2O3 (iron (III) oxide) is +3. This is because oxygen usually has an oxidation number of -2, and since there are three oxygen atoms in Fe2O3, the total oxidation number contributed by oxygen is -6. This means the Fe atoms must have a combined oxidation number of +6 to balance the charge, leading to an oxidation number of +3 for each Fe atom.
-2. oxygen as oxide is always -2 (it is notionally present as O2- )
The oxidation number of oxygen (O) in the compound H2O (water) is -2. Hydrogen typically has an oxidation number of +1 in compounds, so the two hydrogen atoms in water have a combined oxidation number of +2. Since the overall charge of the compound is neutral, the oxidation number of oxygen must be -2 to balance out the charge.
The oxidation number of oxygen is -2 in most of its compounds
