Question

Which pairs of elements among the following will form most stable ionic bond:

Solution

Correct option is

Na and F

 

Polarising power of Mg2+ and Li+ will be higher than that of Na+ due higher charge and smaller size respectively. Now polarisability of F will be less than that of Cl due to moller size
