Homework Statement
Order the following compounds in order of increasing lattice energy:
AlN, BaTe, KCl, Rb2Se
Homework Equations
The Attempt at a Solution
Ok I know that as the distance between the two nuclei decreases and as the charge of the cation and anion increase the lattice energy increases, so I thought the order would be
KCl, BaTe, Rb2Se, AlN however this is wrong...I'm not sure why but I think the Rb2Se is confusing me anyway I would appreciate it if someone could help me out here
