Homework Help: Lattice Energy

  1. Feb 10, 2012 #1
    1. The problem statement, all variables and given/known data
    Place the following in order of decreasing magnitude of lattice energy.

    KF, MgS, RbI

    I'm not really sure how to do this without looking up the lattice energy values with each. And I don't think that is what our teacher wants us to do

    Think just in terms of charges and radii of the ions. This is about simple Coulomb forces.
