How does the actinoid contraction compare to the lanthanoid contraction in terms of magnitude?

Options

  1. AThe actinoid contraction is smaller.
  2. BThe actinoid contraction is larger.
  3. CBoth contractions are of similar magnitude.
  4. DThe paragraph does not provide this information.

Correct answer

B. The actinoid contraction is larger.

Step-by-step solution

The actinoid contraction is greater from element to element, implying that it is larger in magnitude compared to the lanthanoid contraction.
