The chemical bond fonned due to electron trdllsfer is called ionic bond or electro valcnt bond, Ionic bond will be formed more easily between the elements with low ionization potential and high electron affinity. Energy changes involved during the fonnatioo of ionic compound can be calculated by Born-Haber cycle. Lattic enthalpy changes are directly proportional to the stability of ionic compound Most stable ionic compound among the following is
