Actual Bond Energy given Electronegativity in Electronegativity Formulas

The Actual Bond Energy given Electronegativity is defined as the amount of energy required to break apart a mole of molecules into its component atoms. And is denoted by E_(A-B). Actual Bond Energy given Electronegativity is usually measured using the Joule for Energy. Note that the value of Actual Bond Energy given Electronegativity is always negative.
