No any ionic bond would have 100% ionic character.Because for this E.N difference must be 37% that couldn't be achievable.The max. ionic character is 92% that of CsF

Answer / meesum timar khan

If the electronegativity difference between the bonded atoms is 1.7 or more than that,then the bond is said to be ionic.Keeping this in view,NaCl has 72% ionic character.CsF has 92% ionic character and calculations tell us that there is no bond with 100% ionic character.

Answer / tomjerry

because F has less size and CS has greater size so F has
greater ionization energy and CS has low ionization
energy.when we compared F and CS we get low value of EN. we
get not the value 1.7plus1.7is equal to the3.4EN, 3.7 is the
value where bond is 100persent ionic or we get not this
value so ionic in chemistry is not 100persent ionic
