In the cubic crystal of CsCl (

d = 3.97 \text{ g cm}^{-3}

) the eight corners are occupied by

\text{Cl}^-

with a

\text{Cs}^+

at the centre and *vice-versa*. Calculate the distance between the neighbouring

\text{Cs}^+

and

\text{Cl}^-

ions. What is the radius ratio of the two ions? [Atomic mass of Cs = 132.91 and Cl = 35.45]
