Solution

Lanthanoid contraction is the gradual decrease in the atomic and ionic radii of lanthanoids with increase in the atomic number.
Th consequences of lanthanoid contraction include the following.
(a) The basicity and ionic character of hydroxides decreases from La to Lu.
(b) The atomic radii of the elements which follow lanthanum are similar to that of the elements of previous period.
