# 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 - Chemistry

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.

#### Solution 1

Cr2072- and Cr042- (Group number = Oxidation state of Cr = 6).

Mn04  (Group number = Oxidation state of Mn = 7).

#### Solution 2

Vanadate, VO_3^(-)

Oxidation state of V is + 5.

Chromate, CrO_4^(2-)

Oxidation state of Cr is + 6.

Permanganate, MnO_4^(-)

Oxidation state of Mn is + 7.
