Oxidation number of MN is +4. Oxidation number of Oxygen is -2
The oxidation number of Mn in manganese VII oxide is +7.
-6 is the oxidation number
I assume you mean the oxidation number of Mn in the permanganate ion , MnO4- The sum of the oxidation numbers is the charge on a polyatomic ion so Mn has an oxidation number of +7 as each O is assigned -2.
O.S. of Mn in Mn(CO)2 is 0.

MnO2: oxidation number +4KMnO4: oxidation number +7
Ag2MnO4
K has an oxidation number of +1 O has an oxidation number of (-2) x 4 So... the oxidation number for Mn is whatever is needed to make 1-8 equal to zero. Therefore, the oxidation number for Mn is +7
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)

The oxidation number of Mn in the molecule Mn2 would be 0.
