Actinides exhibit larger number of oxidation state than that of corresponding lanthanides. The reason behind this aspect is

Options

  1. Alesser energy difference between 5f5 f and 6d6 d-orbitals than between 4f4 f and 5d5 d-orbitals
  2. Blarger atomic size of actinides than the lanthanides
  3. Cmore energy difference between 5f5 f and 6d6 d orbitals than between 4f4 f and 5d5 d-orbitals
  4. Dgreater reactive nature of the actinides than the lanthanides

Correct answer

A. lesser energy difference between 5f5 f and 6d6 d-orbitals than between 4f4 f and 5d5 d-orbitals

Step-by-step solution

Because of lesser energy difference between 5f5 f and 6d6 d orbitals than that between 4f4 f and 5d5 d-orbitals actinides exhibit larger number of oxidation state than that of corresponding lanthanides.
