What is Bond energy?

In chemistry, bond energy, also called the mean bond enthalpy or average bond enthalpy is the measure of bond strength in a chemical bond. IUPAC defines bond energy as the average value of the gas-phase bond-dissociation energy for all bonds of the same type within the same chemical species.

What is Pauling scale?

Pauling scale is a numerical scale of electronegativities based on bond-energy calculations for different elements joined by covalent bonds. Electronegativity is the power of an atom when in a molecule to attract electrons to itself. Fluorine is the most electronegative element with a Pauling electronegativity value of 4.
