electronegativity difference is the index ofionic chracter.More the differance more the ionic chracter and vice versa.it mean bond will be 100 % ionic when Electronegativity difference is maximum the bond will be purely ionic.no atom is the univers have Electronegativity 0 till now. so no bond in chemistry may 100% ionic
