What is the relationship between lattice energy and the strength of the attractive force holding ions in place?

This question is all over the Internet for some reason - here is a very informative site for your research: Chapter 6: Intramolecular and Intermolecular Forces and Molecular Energy; Chemical and Physical Bonding (http://www.wpi.edu/Academics/Depts/Chemistry/Courses/General/concept6.html)

Please post each question once.
