Assigning Oxidation Numbers 1. Free uncombined elements are given a zero. 2. Monatomic ions have oxidation numbers equal to their charges. 3. In compounds, F is always assigned a -1. The rest of the halogens are usually -1 unless they are with Oxygen and then they have positive values. 4. In compounds, O is usually -2.

Unformatted text preview: Exceptions are peroxides where each oxygen atom is a -1 and superoxides where each oxygen atom is a -1/2. 5. In compounds with nonmetals H is assigned a +1, but in compounds with metals H is assigned a -1. 6. The sum of the oxidation numbers on all the atoms must equal the overall charge on the species....
