What is the term used to describe the cumulative effect of the contraction of the lanthanoid series?

Options

  1. AAtomic contraction
  2. BIonic contraction
  3. CLanthanoid contraction
  4. DNuclear contraction

Correct answer

C. Lanthanoid contraction

Step-by-step solution

The cumulative effect of the contraction of the lanthanoid series, known as lanthanoid contraction, causes the radii of the members of the third transition series to be very similar to those of the corresponding members of the second series.
