Im having trouble figuring out the oxidation states? Can anyone explain how to find these? Thanks!

Oxidation numbers can be calculated through the expected charges of elements found by their positions on the periodic table. For example, halogens have an expected charge of -1, elements in group 16 have an expected charge of -2, alkali metals have an expected charge of +1, etc.

Look at a neutral compound like FeO. Since we know O has a -2 charge, we can assume that Fe has a +2 charge in order to make the compound neutral.

Hope that helps!
