+7.
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.
Manganese oxidation state = +7 So, it is also called Manganate(VII)
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 KMnO4 is +7. This can be determined by assigning the known oxidation numbers of potassium (+1) and oxygen (-2) and solving for the unknown oxidation number of manganese.
First O has an oxidation number of -2; K will an oxidation number of +1 as it is an alkali metal. Therfore the Mn is +6. note that while the manganate ion exists, the question may relate to the permanganate ion MnO4-, so KMnO4, where Mn has oxidation number of +7

MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
The oxidation number for oxygen in KMnO4 is -2. The total oxidation number for the compound must equal zero (since it is neutral), and since the oxidation number for potassium (K) is +1 and for manganese (Mn) is +7, the oxidation number for oxygen must be -2 to balance the charges.
In KMnO4, the oxidation numbers are: K(+1), Mn(+7), and O(-2).
In KMnO4, Mn has an oxidation number of +7, KNO2 has N with an oxidation number of +3, and H2SO4 has S with an oxidation number of +6. In MnSO4, Mn has an oxidation number of +2, H2O has O with an oxidation number of -2, KNO3 has N with an oxidation number of +5, and K2SO4 has S with an oxidation number of +6.
Lets say the oxidation number of Mn is x oxygen's oxidation number is -2 and the charge on the molecule is 1- so: 1(x) + 4(-2) = 0 x - 8 = 0 x = +8 and then you must remember that there is a negative charge to the molecule. Subtract 1. therefore oxidation number on Mn is +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
