We’re gift asked to recognize theoxidation state that manganeseinMnO2 (manganese (IV) oxide).
You are watching: Oxidation number of manganese in mno2
The rules for oxidation says are together follows:
A. General Rules:
1. Because that an atom in that is 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, through nonmetals
O.S. = –1 with metals and also boron
4. Fluorine O.S. = –1
5. Oxygen O.S. = –1 in peroxides (X2O2, X = team 1A)
O.S. = –1/2 in superoxides (XO2, X = group 1A)
O.S. = –2 in various other compounds
6. Team 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.
