WebThe lattice energy is the total potential energy of the crystal. The lattice energy is usually given in kilojules per mole (kJ/mol). The science, which deals with crystals properties is crystallography. There are theroretical models, which allow to calculate (with better or worse result) the lattice energy. WebHow do you find lattice energy? First, find the charges of the ions in the compound. Second, place them in order of increasing or decreasing based on charge. Third, if the charges are the same look at the position on the periodic table. Lattice energy increases as you move up the periodic table.
