In MnO4- What is the Oxidation Number of Mn

Q. In  MnO4– What is the oxidation number of Mn?

Ans: The total number of electrons that an atom acquires or loses in order to create a chemical connection with another atom is known as the oxidation number, also known as the oxidation state.

An oxidation-reduction reaction assigns an oxidation number to each atom that indicates its ability to acquire, donate, or share electrons. In inorganic chemistry nomenclature, the oxidation number of an element that can exist in more than one oxidation state is represented by a roman numeral in parentheses after the name of the element in inorganic chemistry nomenclature—for example, iron(II) chloride (FeCl2) and iron(III) chloride (FeCl3) 

Let Mn’s oxidation number be x.

We know that oxidation number of O is -2

As a result, oxidation number of Mn+4 (oxidation number of O)

-1x + 4(-2) = -1

x – 8 = -1

x = +8 -1

x = +7

Therefore, Mn has an oxidation number of +7
