Lattice enthalpy and lattice energy are commonly used as if they mean exactly the same thing - you will often find both terms used within the same textbook article or web site, including on university sites. The bond between ions of opposite charge is strongest when the ions are small. Work performed under the auspices of the U.S. Atomic Energy Commission. For the ionic solid MX, the lattice energy is the enthalpy change of the process: value. The associated salt formula and salt class is presented for each value along with the lattice energy U pot BFHC in kJ/mol, if given in [1]. This page introduces lattice enthalpies (lattice energies) and Born-Haber cycles. Therefore, BeO is insoluble in water. See the answer. Therefore, it is almost insoluble in water. This is because of small size of Be than Mg. The energy between ions can be calculated with the help of Coulomb’s Law. The following table shows calculated values of the total lattice potential energies, U pot in kJ/mol, for crystalline salts given by H. D. B. Jenkins and H. K.
