$Li^{+}$

Vedclass · Answer

(A) The polarising power of a cation is determined by its ionic potential,which is the ratio of charge to size $(Z/r)$.Lithium $(Li^{+})$ and Magnesium $(Mg^{2+})$ exhibit a diagonal relationship in the periodic table.This diagonal relationship arises due to their similar ionic potential values,which results in similar polarising power and electronegativity.Therefore,the polarising power of $Mg^{2+}$ is very close to that of $Li^{+}$.

Magnesium cation $(Mg^{2+})$ has a polarising power close to that of:
