Since is in column of the periodic table, it will share electrons and use an oxidation state of . Because it is more electronegative than most metals, phosphorus reacts with metals at elevated temperatures to form phosphides, in which it has an oxidation number of -3. The general idea is that electrons are transferred between charged atoms. The rules are that the oxidation number of combined oxygen is -2, except in peroxides like H2O2, where it is -1.
