![]() ![]() Therefore lattice energy for NaCl is 756 KJ per mol. They do not easily deform, as well as they melt at relatively high temperatures. Ionic compounds are usually rigid, brittle, crystalline substances with flat surfaces in a lattice form. It is, electrons transfer from the metal to the non-metal. Recall that the reaction of a metal with a non-metal usually produces the ionic compound. Given the following information, determine the lattice energy for sodium bromide. Use the Born-Haber cycle to calculate the lattice energy of NaBr (s) given the following data: Delta H (sublimation, Na) 109 kJ/mol I1 (Na) 496 kJ/mol Bond energy (Br-Br) 192 kJ/mol EA. Lattice energy can be a very complicated process but it can be easily understood by using Coulomb’s law. The attraction of the two ions releases energy, so this process is of an exothermic kind. Sodium iodide is very dissolved in water to have an ion structure of a lattice of an ionic crystal grid.Lattice energy refers to the energy which is released while two oppositely charged gaseous ions attract to each other and form an ionic solid.
