The sBlock Elements - Result Question 9
####10. In crystals of which one of the following ionic compounds would you expect maximum distance between centres of cations and anions? [1998]
(a) $LiF$
(b) $CsF$
(c) CsI
(d) $Lil$
Show Answer
Solution:
- (c) $As Cs^{+}$ion has larger size than $Li^{+}$and $I^{-}$ has larger size than $F^{-}$, therefore maximum distance between centres of cations and anions is in CsI.
