The density of a crystal is inversely related to the equilibrium constant. The dissociation energy of a salt is large when the equilibrium separation distance is small. The densities and equilibrium radii for common salts (FCC) are nearly the same.

An ionic bond transfers an electron from one atom to another, and a covalent bond shares the electrons. The energy change associated with ionic bonding depends on three main processes: the ionization of an electron from one atom, the acceptance of the electron by the second atom, and the Coulomb attraction of the resulting ions. Covalent bonds involve space-symmetric wave functions.
