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.
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 Mn in Mn2O3 is +3. Oxygen has an oxidation number of -2, and there are three oxygen atoms in Mn2O3, so the overall charge of the compound is balanced out by the +3 oxidation state of manganese.
The oxidation number of Mn in MnO4- is +7. This is determined by balancing the charge of the whole ion (-1) with the charges of the oxygen atoms (-8) and solving for the oxidation number of Mn.
The oxidation number of Mn in MnCO3 is +2. MnCO3 is a neutral compound, so the overall sum of the oxidation numbers of all elements in the compound should equal zero. Since the oxidation number of oxygen is typically -2 and there are three oxygen atoms, the oxidation number of Mn must be +2 to balance out the charges.

In MnCl2, the oxidation number of Mn is +2, as it is in the +2 oxidation state. The oxidation number of Cl is -1 each, as it is typically in the -1 oxidation state when bonded to metals such as manganese.
For the MnO4- ion, the oxidation number of oxygen is typically -2. Since the overall charge of the ion is -1, the oxidation number of manganese (Mn) must be +7 to balance out the charges.
-2 for each O, +7 for Mn
In MnCl2, the oxidation number of Mn is +2. This is because each chlorine atom has an oxidation number of -1 and there are two chlorine atoms in MnCl2, so the overall charge must equal zero.
In MnCo2, Mn has an oxidation number of +2, and Co has an oxidation number of -1. This is determined by assigning oxidation numbers based on rules for assigning oxidation numbers to each element in the compound.
The oxidation number of Mn in the molecule Mn2 would be 0.
The oxidation number of Mn in Mn(ClO4)3 is +7. Each Cl has an oxidation state of -1 and each O has an oxidation state of -2. The sum of the oxidation numbers should equal the charge of the molecule, which is 0 in this case.
