Protein quality depends upon

In chemical compound ability of an atom to attract shared electron toward itself is called electronegativity. Various scales are given to measure electronegativity like Pauling scale, Mulliken scale, Allred-Rochow's scale. Electronegatigity of an element also depends on various parameters. If electron of an element is 6eV and ionisation energy is 16.4eV then electronegativity element on Pauling scale is:
