Which of the following expressions is correct in case of a $\mathrm{CsCl}$ unit cell (edge length 'a')?
Solution
$\mathrm{CsCl}$ has body centered type structure in which $\mathrm{Cs}^{+}$ occupies at corner of a cube and $\mathrm{Cl}^{-}$occupies the centre of the cube.<br/><br/>
$2 \mathrm{r}_{\mathrm{Cs}^{+}}+2 \mathrm{r}_{\mathrm{Cl}^{-}}=\sqrt{3} \mathrm{a}$ (where a is the edge length of the cube)<br/><br/>
$$
\mathrm{r}_{\mathrm{Cs}^{+}}+\mathrm{r}_{\mathrm{Cl^-}}=\frac{\sqrt{3}}{2} \mathrm{a}
$$
