Identify the correct decreasing order of atomic radii from following.
  1. $\mathrm{Ce}>\mathrm{Tm}>\mathrm{Pm}>\mathrm{Yb}$
  2. $\mathrm{Ce}>\mathrm{Pm}>\mathrm{Tm}>\mathrm{Yb}$
  3. $\mathrm{Pm}>\mathrm{Yb}>\mathrm{Ce}>\mathrm{Tm}$
  4. $\mathrm{Pm}>\mathrm{Tm}>\mathrm{Ce}>\mathrm{Yb}$

Solution

As $\mathrm{Z} \uparrow \rightarrow$ radius decreases
