Many practice problems for how to calculate and determine oxidation numbers, often referred to as oxidation states. To figure out oxidation numbers for elements in a compound, we have to look on the periodic table and consult a list of rules. For neutral compounds, the oxidation numbers add up to zero. For polyatomic ions, the oxidation numbers add up to charge of the ion.
