Question

Which pair 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 dohigher charge and smaller size respectively.

Now polarisability of F will be less than that of Cl due to moller size 

   NaF should be the most ionic.
