Lattice Energies are always given as negative numbers SIZE Smaller ion ===> more lattice energy Larger ion ===> less lattice energy CHARGE Larger (+ or -) ===> more lattice energy INDIRECT DIRECT

anion (-) charge x its subscript cation (+) subscript Roman numeral after metal cation (+) = Metals in Ionic Cmpds w more than 1 possible charge
