Larger number of oxidation states are exhibited by the actinoids than those by the lanthanoids, the main reason being

Options

  1. A4 f orbitals more diffused than the 5 f orbitals
  2. Blesser energy difference between 5 f and 6 d than between 4 f and 5 d orbitals
  3. Cmore energy difference between 5 f and 6 d than between 4 f and 5 d orbitals
  4. Dmore reactive nature of the actinoids than the lanthanoids

Correct answer

B. lesser energy difference between 5 f and 6 d than between 4 f and 5 d orbitals

Step-by-step solution

Being lesser energy difference between 5 f and 6 d than 4 f and 5 d orbitals.
