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.
