,Oxidation Number
The common oxidation number of OXYGEN is –2
But in peroxides (H₂O₂, Na₂O₂)................... –1
And in superoxides (KO₂, RbO₂)................ –1⁄2
In oxygen difluoride (OF₂).........................+2
Dioxygen difluoride (O₂F₂).........................+1
The common oxidation number of HYDROGEN is +1.
But in metal hydrides, H shows -1.
The common oxidation number of halogens is -1.
