The stability of higher oxidation states on moving down the group in transition elements

A

Decreases

B

Increases

C

Remain same

D

Increases from first series to second and decreases from second to third

Text Solution

Verified by Experts

The correct Answer is:
B
On moving down the group in the transition elements the stability of higher oxidation states increases. This is due to the similarity of the energy of the d orbitals with the outer s orbitals. Hence the d orbitals are more available towards the bond formation.
