We are being asked to explain the following the trend in the lattice energies of the alkaline earth metal oxides:

Metal OxideLattice Energy (kJ/mol)
MgO-3795
CaO-3414
SrO-3217
BaO-3029


Recall:

Lattice Energy=|cation charge·anion charge|cation radius + anion radius

Radius = period (i.e. the row in the periodic table) number


ā€¢ To determine the cation and anion charge, recall that some elements have common charges based on what group they belong to on the periodic table:
