Mg and Li have similar properties due to:- a) same e/m ratio b) same electron affinity c) same group d) same ionic potential Give proper Explaination No link

Dear Student,

Mg and Li have similar properties due to diagonal relationship. They behave similarly due to same polarising power which depends on the ratio of ionic charge to ionic radius, in short they have same ionic potential. 

Ionic Potential = Ionic ChargeIonic radius
Hence, correct answer is (d)
