As (r +/r -) lies in the range 0.732 - 1.000. Hence co-ordination number is 8 and KF is of CsCl type.

Q. Identify the type of crystalline structure adopted by $K F$ solid from the following, if the radius ratio of $K F$ is $0.98$ .

$N a Cl$

$Z n S$

$C s Cl$

$C a F_{2}$

As $\frac{r +}{r -}$ lies in the range $0.732 - 1.000$ . Hence co-ordination number is $8$ and $K F$ is of $C s Cl$ type.
