√2 a=4 rC l- 4 rC l-=(a √2/4)=(a/2 √2)=(512/2 √2) =361.8 pm ≅ 362 pm

Q. $L i Cl$ has $N a Cl$ type structure with edge length $512$ pm. Assuming that the $L i^{+}$ ion is small enough that the chloride ions are in contact, then radius of $C l^{-}$ ion is

$223$ pm

$224$ pm

$181$ pm

$362$ pm

$2 a = 4 r_{Cl}^{-}$
$4 r_{C l^{-}} = \frac{a 2}{4} = \frac{a}{2 2} = \frac{512}{2 2}$
$= 361.8 p m ≅ 362 p m$
