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

To calculate the oxidation number of Mn in KMnO4, set up an equation using the known oxidation numbers of potassium (+1) and oxygen (-2). Since KMnO4 is a neutral compound, the sum of the oxidation numbers must equal zero. Thus, the oxidation number of Mn can be calculated by solving the equation: 2(+1) + x + 4(-2) = 0, where x represents the oxidation number of Mn. Solving for x gives Mn a +7 oxidation number.

What is oxidation number for Me in K2Mno4 -1?

In K2MnO4, the oxidation state of oxygen is -2, and the overall charge of the compound is -1. Given that potassium has a +1 oxidation state, the oxidation state of manganese (Mn) in this compound is +7.


What is the oxidation number of each atoms Mn?

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.


What is the oxidation number of Mn in 2MnO2?

The oxidation number of Mn in MnO2 is +4. Since there are two Mn atoms in 2MnO2, the total oxidation number for both Mn atoms in 2MnO2 is +8.


What is the oxidation number of MN in 2MnO4-?

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.


What is the oxidation number of Mn?

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
