8. The plot of lattice energies for sodium halides \( (\mathrm{F}, \mathrm{Cl}, \mathrm{Br}, \mathrm{I}) \) and alkali metal \( (\mathrm{Li}, \mathrm{Na}, \mathrm{K}, \mathrm{Cs}) \) chlorides is shown to the right. A. List the formulas for these salts. B. Which of these salts will have the largest lattice energy? You should be able to identify the 2 with the largest lattice energy without looking anything up. Which points correspond to those salts on the plot? (Hint: it is not necessarily one of the labelled points.) C. Which of these salts will have the smallest lattice energy? You should be able to identify the 2 with the smallest lattice energy without looking anything up. D. Determine which point on the plot that corresponds to \( \mathrm{NaCl} \).
