Lattice energy$\mathrm{\alpha } \frac{1}{{\mathrm{r}}_{+}+{\mathrm{r}}_{-}}$
With a small anion as${\mathrm{F}}^{-}$, the lattice energy decreases more rapidly along a series of salts with increasing cation size and thus solubility increases

$\mathrm{LiF}<\mathrm{NaF}<\mathrm{KF}<\mathrm{RbF}<\mathrm{CsF}$
