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)
manganese (IV) oxide
manganese has an oxidation number of 4
the oxidation number of mnb in h2mno3 is 4
The oxidation number of Mn in MnO2 is 4+.
+3 for Mn
-1 for F
Oxidation number of MN is +4. Oxidation number of Oxygen is -2
Manganese III's oxidation number is +3 and Nitrate's oxidation number is -1. Because you want the oxidation numbers to add together to make zero, you'd need to use Nitrate three times in the compound: Mn(NO3)3
-6 is the oxidation number
The oxidation number of Mn in manganese VII oxide is +7.
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.

The chemical formula of this is MnO2.It is brown in colour. The oxidation number of Mn is 4 in this compound.
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: oxidation number +4KMnO4: oxidation number +7
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
The oxidation number of Mn in the molecule Mn2 would be 0.
Ag2MnO4
In the anions of oxyacids, oxygen is always assigned an oxidation number of -2. Therefore, in an MnO4-1 anion, manganese must have an oxidation number of +7 to achieve electrical balance for the anion. (There is no neutral compound with the formula MnO4.)
