Question

Among the following which one has the highest cation of anion size ratio? (A) CsI (B) CsF (C) LiF (D) NaF

Tardigrade Admin · Accepted Answer

The size of cation is in order of- L i+ < N a+ < C s+ and the size of anions in the order of- I- > F- Thus, when the cation is largest and anion is smallest, the ratio of their sizes is maximum. Hence, cation to anion size ratio is maximum for CsF.

NaF

The size of cation is in order of- $L i^{+} < N a^{+} < C s^{+}$
and the size of anions in the order of- $I^{-} > F^{-}$
Thus, when the cation is largest and anion is smallest, the ratio of their sizes is maximum.
Hence, cation to anion size ratio is maximum for $C s F$ .
