CsCl crystallises in body centred cubic lattice. If ‘a’ is its edge length then which of the following expressions is correct?

Accepted Answer

Relation between radius of cation, anion and edge length of the cube

2 r_{C s^{+}} + 2 r_{C l^{-}} = \sqrt{3} a

\Rightarrow r_{C s^{+}} + r_{C l^{-}} = \frac{\sqrt{3} a}{2}
