Amount of energy that holds a crystal together, the energy change when a mole of solid is formed from its constituent molecules or ions (for ionic compounds) in their gaseous state.

The energy charge when one mole of formula units of a crystalline solid is formed from its ions, atoms, or molecules in the gas phase, always negative.
