The radius of $La^{3 +}$ (Atomic number of $La = 57$ ) is $1.06 \overset{˚}{A}$ . Which one of the following given values will be closest to the radius of $Lu^{3 +}$ (Atomic number of $Lu = 71$ )?

Options:

Answer:

Solution:

$Ω \propto \frac{1}{Z}$ $\frac{Ω _{1}}{Ω _{2}} = \frac{z _{2}}{z _{1}} \Rightarrow \frac{1.06}{Ω _{2}} = \frac{71}{57} \Rightarrow Ω_{2} = 0.85 \overset{˚}{A}$
