The energy required to break a given type of bond between atoms in certain valence
states. An averaged bond energy is commonly derived by dissecting the heat of atomization
of a molecule into contributions of individual bonds. For molecules with localized
bonds, the heats of atomization (formation) are usually well approximated by the sum
of pertinent averaged bond energies.
