Problem: Which of the following ionic solids have the largest magnitude lattice energy?A. NaF B. CaCl2 C. CaBr2 D. CaOE. NaCl

We’re being asked to determine the ionic compound with the magnitude lattice energy.

The lattice energy can be estimated using:

$\boxed{\mathbf{lattice}\mathbf{ }\mathbf{energy}\mathbf{=}\frac{\left|\mathbf{cation}\mathbf{ }\mathbf{charge}\mathbf{\times }\mathbf{anion}\mathbf{ }\mathbf{charge}\right|}{\mathbf{cation}\mathbf{ }\mathbf{period}\mathbf{ }\mathbf{\#}\mathbf{ }\mathbf{+}\mathbf{ }\mathbf{anion}\mathbf{ }\mathbf{period}\mathbf{ }\mathbf{\#}}}$
