WebIn chemistry, bond energy (BE), also called the mean bond enthalpy or average bond enthalpy is a measure of bond strength in a chemical bond. IUPAC defines bond energy as the average value of the gas-phase bond-dissociation energy (usually at a temperature of 298.15 K) for all bonds of the same type within the same chemical species.. The bond … WebThis derivation also assumed that all bonds were the same. In fact, many materials, especially biological materials, have many different types of bonds. In this case, the weakest of the bonds is the primary determinant of the Young’s modulus, just as the stiffness of springs in parallel is dominated by the softest springs.
