• New electronegativity scale
• Bond dissociation energy

The bond dissociation energies of some diatomic molecules (in both covalent and ionic forms) are estimated from different formulas and using a new scale of electronegativity. The calculated bond dissociation energies are compared with those which are obtained from the other commonly used electronegativity, scales such as Pauling and Allred-Rochow. The best linear correlation is observed between the obtained bond dissociation energies from new electronegativity scale and experimental data. Comparison between the corrected results, which are calculated from the linear relationship equations for different scales, shows that in both covalent and ionic bonds the new scale of electronegativity represents a better correlation with the experimental data than the others. This indicates the reliability of the obtained results from the new scale.
