The oxidation number of manganese in KMnO4 is 7+.
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.
The oxidation number of manganese in 1 mole of permanganate (MnO4-) is +7. Each oxygen atom has a charge of -2 and the overall charge of the ion is -1, so the oxidation number of manganese can be calculated as +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
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.)

+7
The oxidation number of Mn in MnO4 is +7. This is because oxygen is almost always assigned an oxidation number of -2, so the total oxidation number for the entire MnO4 ion must be -1. Since there is one Mn atom in MnO4, the oxidation number of Mn must be +7 to make the total -1 charge balance out.
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 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.
-2 for each O, +7 for Mn
MnO4- is the chemical formula for permanganate. The charge is generally -1.
Permanganate Symbol is MnO4- Valency of the ion is -1, the manganese is +7 and the oxygen -2. Potassium Permanganate symbol is KMnO4.
The oxidation number of manganese in KMnO₄ is +7. Manganese has an oxidation number of +7 in this compound because oxygen has an oxidation number of -2, and the overall charge of the permanganate ion is -1, so the sum of the oxidation numbers must equal -1.
