I'm having some problems with the calculations associated with this problem:(adsbygoogle = window.adsbygoogle || []).push({});

Which compound in each of the following pairs of ionic substances has the most exothermic lattice energy?

(a) LiF

CsF

I know I need to use Coulomb's law, but I don't know how to calculate r (the distance between the ion centers)

Any help is greatly appreciated. Thanks
