Simple ionsOxidation number is the same as thecharge for simple ions3. addition of all oxidation numbersin a neutral compoundall oxidation numbers in a neutral compoundmust add up to 04. addition of all oxidation numbers in a charged compound addition of all oxidation numbers in a charged compound must add up to the chargeof the compound5. usual oxidation numberfor an elementusual oxidation number of anelement is equal to its charge6. Exceptions to rule 5some elements' oxidation numbers can changedue to the other elements in the compound
