Name the oxometal anions of the first series of the transition metals in which the metal exhibits the oxidation state equal to its group number.

Text Solution

Verified by Experts

The correct Answer is:
`CrO_(7)^(2-)` and `CrO_(4)^(2-)` (Group No. =Oxidation state of Cr=6)
`MnO_(4)^(-)`(Group No=Oxidation state of Mn=7)
