How to find oxidation state of Mn2O​

Answer»

Answer:

The oxidation NUMBER of the OXIDE anion is -2 . Since there are 2 oxide ions, the total oxidation number for the oxide is -4 . Since the sum of the oxidation numbers must be 0 , the oxidation number of the manganese cation is +4 . Therefore, MnO2 is the IONIC COMPOUND manganese(IV) oxide.
