MnO2 manganese(IV) oxide. Oxygen has a -2 oxidation state (oxidation state is a better term here as oxidation number is better used for complexes- they give the same answer for this compound)
For an uncombined atom, the oxidation number is 0. It does not give away any electrons. It does not accept electrons from anywhere either.
Carbon is in the 14th group. Carbon normally shows +4 oxidation number.
oxidation number of I is -1. oxidation number of F is +1.
In the compound Co2O3 cobalt has an oxidation number of 3 while oxygen has an oxidation number is -2.
