Electronegativity difference is the index of ionic
character. More the differance more the ionic character and
vice versa. it mean bond will be 100% ionic when
Electronegativity difference is maximun (one atom have
Electronegativity 4 and other have 0) the bond will be
purely ionic. no atom is the univers have Electronegativity
0 till now.
so no bond in chemistry may 100% ionic.
