- In crystal: Metallic bonds
Cohesive energy is the energy gained by arranging the atoms in a crystalline state, as compared with the gas state. Insulators and semiconductors have large cohesive energies; these solids are bound together strongly and have good mechanical strength. Metals with electrons in sp-bonds have very…

…by introducing the concept of cohesive energy density, which is defined as the potential energy of a liquid divided by its volume. The adjective cohesive is well chosen because it indicates that this energy is associated with the forces that keep the molecules close together in a condensed state. Again…
