When the metal can exist in more than one oxidation state (apex)
When the metal can exist in more than one oxidation state
The oxidation state of Mn in the compound Mn2 is +2. Each Mn atom has an oxidation state of +2, as indicated by the subscript 2 in the formula Mn2.
Romann numerals are used: (I), (II)...
The oxidation state of oxygen in the compound is -2.
The subscript of the second ion identifies the oxidation state of the transition metal

The oxidation state of oxygen in the compound is -2.
The subscript of the second ion identifies the oxidation state of the transition metal
The oxidation state of a transition metal is determined by the number of electrons it has lost, gained, or shared when forming compounds. This is typically indicated in the compound's formula by using Roman numerals to denote the oxidation state, such as in iron (III) oxide (Fe₂O₃), where iron has an oxidation state of +3. To identify the oxidation state, one can analyze the overall charge of the compound and the charges of the other elements involved, allowing for a systematic determination of the metal's oxidation state.
The compound with the highest oxidation number would be an oxide of fluorine, such as OF₂. In this compound, the oxidation state of fluorine is +2, which is the highest oxidation state observed for fluorine.
The oxidation state of the manganese atom in the compound KMnO4 is 7.
