Why is actinoid contraction greater from element to element than lanthanoid contraction?

Options

  1. AActinides have a higher atomic number than lanthanides.
  2. BActinides experience a stronger effective nuclear charge than lanthanides.
  3. Cbecause the 5f electrons themselves provide poor shielding from element to element in the actinoid series.
  4. DActinides have a greater affinity for oxygen and fluorine.

Correct answer

C. because the 5f electrons themselves provide poor shielding from element to element in the actinoid series.

Step-by-step solution

Correct Option is : (C) because the 5f electrons themselves provide poor shielding from element to element in the actinoid series.
