Lattice Energy Definition
Lattice energy is a measure of the strength of the electrostatic forces that hold ions together in an ionic crystal. It is defined as the energy required to separate all the ions in one mole of an ionic compound into gaseous ions.
Lattice energy is an important property of ionic compounds because it determines many of their physical and chemical properties, such as their solubility, melting point, and boiling point.
MX3 Compounds
MX3 compounds are a class of ionic compounds that have the general formula MX3, where M is a metal and X is a non-metal.
MX3 compounds are typically formed when a metal reacts with a non-metal in a 1:3 ratio. For example, sodium reacts with chlorine to form sodium chloride (NaCl).
Determining Lattice Energy, Determine the lattice energy of mx3
The Born-Haber cycle is a method for calculating the lattice energy of an ionic compound. The Born-Haber cycle is based on the following equation:
