O2 is -2
so Mn is +4
In MnO2, the oxidation number of oxygen is typically -2. Since there are two oxygen atoms in MnO2, the total oxidation number contributed by oxygen is -4. The overall charge of the compound is neutral, so the oxidation number of manganese (Mn) can be calculated by setting the total oxidation number equal to zero. Therefore, the oxidation number of Mn in 2MnO2 is +4.
The oxidation number of manganese changes from +4 in MnO2 to +3 in Mn2O3. This indicates a reduction of the manganese atom.
The oxidation number of manganese (Mn) can vary depending on the compound it is in. In MnO2, the oxidation number of Mn is +4, while in KMnO4, the oxidation number of Mn 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 oxidation state for manganese in MnO2 is +4. Oxygen typically has an oxidation state of -2, so the sum of the oxidation states in MnO2 would be 0. Since there are two oxygen atoms with an oxidation state of -2 each, the manganese atom must have an oxidation state of +4 to balance the equation.

The change in oxidation number of Mn in a reaction is determined by the difference in oxidation numbers before and after the reaction. For example, in the reaction MnO2 → Mn2O3, the oxidation number changes from +4 to +3, resulting in a decrease of 1.
The oxidation number of manganese depends on the particular compound in which manganese is present. The most common oxidation states are +2 as in MnCl2, + 4 as in MnO2, and + 7 as in potassium permanganate, KMnO4.
The oxidation number for Mn in H2MnO3 is +3. In this compound, oxygen is typically assigned an oxidation number of -2, and hydrogen is +1. By considering the overall charge of the compound and assigning hydrogen and oxygen their usual oxidation states, the oxidation number of Mn can be calculated as +3.
The chemical formula of this is MnO2.It is brown in colour. The oxidation number of Mn is 4 in this compound.
