How to find the Oxidation Number for Cr in Cr2O3 | Chromium (III) oxide
To find the correct oxidation state of Cr in Cr2O3 (Chromium (III) oxide), and each element in the molecule, we use a few rules and some simple math. First, since the Cr2O3 molecule doesn’t have an overall charge (like NO3- or H3O+) we could say that the total of the oxidation numbers for Cr2O3 will be zero since it is a neutral molecule. We ...
