We’re gift asked to recognize theoxidation state the manganeseinMnO2 (manganese (IV) oxide).

You are watching: What is the oxidation number of manganese in mno2?

The rules because that oxidation states are together follows:

A. Basic Rules:

1. For an atom in its elemental kind (Zn, Cl2, C(graphite), etc.) O.S. = 0

2. For an ion (Li+, Al3+, etc.) O.S. = charge

B. Specific Rules:

1. Team 1A O.S. = +1

2. Group 2A O.S. = +2

3. Hydrogen O.S. = +1, with nonmetals

O.S. = –1 with metals and also boron

4. Fluorine O.S. = –1

5. Oxygen O.S. = –1 in peroxides (X2O2, X = group 1A)

O.S. = –1/2 in superoxides (XO2, X = group 1A)

O.S. = –2 in various other compounds

6. Group 7A O.S. = –1 (except once bonded to O)

Since Mn2O3 is neithera peroxide or superoxide,the oxidation state of each oxygen atom is –2.
