Chemistry - CHEMICAL BONDING Question with Solution | TestHub

$\begin{array}{l}\mathrm{L}\mathrm{a}\mathrm{t}\mathrm{t}\mathrm{i}\mathrm{c}\mathrm{e}\mathrm{ }\mathrm{E}\mathrm{n}\mathrm{e}\mathrm{r}\mathrm{g}\mathrm{y}\propto \frac{{\mathrm{q}}_1{\mathrm{q}}_2}{{\mathrm{r}}_{\mathrm{c}}+{\mathrm{r}}_{\mathrm{a}}}\end{array}$

Where q represents charge of ion and r represent radius of ion.
Lattice energy does not dependent packing of ions.
