Q.

The effect of lanthanoid contraction in the lanthanoid series of elements by and large means :

  1. A

    decrease in both atomic and ionic radii 

  2. B

    increase in atomic radii and decrease in ionic radii

  3. C

    increase in both atomic and ionic radii 

  4. D

    decrease in atomic radii and increase in ionic radii 

Solution

Due to Lanthanoid contraction both atomic radii and ionic radii decreases gradually in the lanthanoid series.
