Answer Posted / imran haider
As electronegativity difference is the index of ionic
character.If the electronegativity difference is greater
than 1.7,then the bond is ionic in charcter.The largest
electronegative element is the Fluorine (4.0) and the lowest
electronegative element is Cesium (0.7),their E.N difference
is 3.3,they are just 92% ionic.For 100% ionic character,the
E.N difference should be 3.7,so no bond in Chemistry is 100%
ionic in charcter.
