Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4{2-} or NH2NH3{+}. Enter just an element symbol to show the common and uncommon oxidation states ...
Once you have drawn the lewis diagram for (Mo2)O3, you can look at each bond and assign its electrons to the more electronegative species. Bonds in (Mo2)O3 Calculate Oxidation Numbers To get the average oxidation number of each element, sum up the charge in each column, making sure to...
