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

Multiple Choice Options

  • A 4f orbitals more diffused than the 5f orbitals
  • B lesser energy difference between 5f and 6d than between 4f and 5d orbitals
  • C more energy difference between 5f and 6d than between 4f and 5d orbitals
  • D more reactive nature of the actinoids than the lanthanoids

Step-by-Step Verified Solution

NOTE : The main reason for exhibiting larger number of oxidation states by actinoids as compared to lanthanoids is lesser energy difference between 5f5f and 6d6d orbitals as compared to that between 4f4f and 5d5d orbitals.
