Monotomic ions? Like Fe- charge on the ion
Oxygen? -2 in most compounds

Compounds and ions? The sum of the oxidation # of the atoms in a compound equals zero. In polyatiomic ion the sume of the oxidation numbers equals the charge of the ion.
What rule allows you to see if your correct? The rule for Compounds and ions.
