In chemistry, bond energy (E) is the measure of bond strength in a chemical bond. It is the heat required to break one Mole (unit) of molecules into their individual atoms. For example, the carbon-hydrogen bond energy in methane E(C–H) is the enthalpy change involved with breaking up one molecule of methane into a carbon atom and 4 hydrogen radicals divided by 4.
Bond energy (E) should not be confused with bond-dissociation energy. It is a roughly transferable property, and enthalpy of formation can typically be roughly approximated by simply adding tabulated values for bond energies for all bonds in a molecule, with an error of sometimes just a few percent. However, to get a better approximation is much more difficult.

Famous quotes containing the words bond and/or energy:
“Every doctor will allow a colleague to decimate a whole countryside sooner than violate the bond of professional etiquet by giving him away.”
—George Bernard Shaw (1856–1950)
“Perhaps catastrophe is the natural human environment, and even though we spend a good deal of energy trying to get away from it, we are programmed for survival amid catastrophe.”
—Germaine Greer (b. 1939)
