Vedclass · Answer

(C) Lanthanoid contraction is the steady decrease in the atomic and ionic radii of lanthanoids with an increase in atomic number.Due to lanthanoid contraction,the elements of the $4d$ and $5d$ transition series,specifically $Zr$ $(Z=40)$ and $Hf$ $(Z=72)$,exhibit almost identical atomic and ionic radii.This similarity in size makes the separation of $Zr$ and $Hf$ very difficult.

Lanthanoid contraction is responsible for which of the following?
