The most important oxidation numbers for phosphorus are -3, +3, and +5 (see table below). 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. Herein, does o2 have an oxidation number? Rules for assigning oxidation numbers The oxidation number of a free element is always 0. The oxidation number of a monatomic ion equals the charge of the ion. Oxygen almost always has an oxidation number of -2, except in peroxides (H2O2) where it is -1 and in compounds with fluorine (OF2) where it is +2.What is the oxidation number of co2?The oxidation number of C in carbon dioxide (CO2) is (rules 1 & 2): 0 + (2 x 2) = +4 [Check (rule 3): +4 + 2(-2) = 0] The oxidation number of C in methane (CH4) is (rules 1 & 2): 0 – (4 x1) = -4 [Check (rule 3): -4 + 4(-1) = 0].
