What is the oxidation number of oxygen in potassium oxide,
WEBJan 2, 2017 · Oxidation number is the charge left on the atom of interest, when all the bonding electrons are removed with the charge devolved to the more electronegative atom. We have the ionic salt, K_2O. Clearly, oxygen is more electronegative than potassium, and so we have 2xxK^ (+)+O^ (2-). The oxidation number of O in oxide anion is thus -II.
