SUMMARY
The oxidation numbers for manganese (Mn) in the compounds discussed are as follows: KMnO4 has an oxidation number of +7, LiMnO2 has +1, MnO2 has +4, K2MnCl has +1, and Mn2O7 has +7. The oxidation number calculations require understanding the charges of constituent elements, particularly that potassium (K) has a +1 charge and oxygen (O) has a -2 charge. Proper computation involves balancing the total charge to zero for neutral compounds.
