Larger number of oxidation states are exhibited by the actinoids than those by the lanthanoids, the main reason being:
- 4f orbitals more diffused than the 5f orbitals
- lesser energy difference between 5f and 6d than between 4f and 5d orbitals
- more energy difference between 5f and 6d than between 4f and 5d orbitals
- more reactive nature of the actinoids than the lanthanoids
Answer
(B) lesser energy difference between 5f and 6d than between 4f and 5d orbitals
