What is the net result of the lanthanoid contraction on the second and third d series?

Options

  1. AIt causes a decrease in radii.
  2. BIt causes an increase in radii.
  3. CIt has no effect on radii.
  4. DIt causes a significant increase in radii.

Correct answer

C. It has no effect on radii.

Step-by-step solution

The net result of the lanthanoid contraction is that the second and third d series exhibit similar radii.
