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.
MnO2 is called manganese IV oxide because manganese has a +4 oxidation state in this compound. The Roman numeral IV indicates that manganese is in the +4 oxidation state, where it has lost four electrons.
The oxidation number of manganese changes from +4 in MnO2 to +3 in Mn2O3. This indicates a reduction of the manganese atom.
The bond between manganese and oxygen in a compound can vary depending on the oxidation state of manganese. For example, in manganese(II) oxide (MnO), the bond is typically considered ionic with a formula of Mn2+O2-. In manganese dioxide (MnO2), the bond is covalent with a formula of MnO2.
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.

In the given reaction, the manganese atom changes from a +7 oxidation state in potassium permanganate (KMnO4) to a +4 oxidation state in manganese dioxide (MnO2), indicating that the manganese atom is reduced.
MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
The oxidation state for manganese in Mn is 0, since it is in its elemental form.
MnO Mn2+ and O2- = Mn2O2 but you'd simplify and it becomes MnO
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.
