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:
