Vedclass · Answer

(A) According to Fajan's rule,the ionic character of a bond depends on the polarizability of the cation. Smaller cations with high charge density have a greater tendency to polarize the anion,leading to increased covalent character. Among the given metals,$Be^{2+}$ has the smallest ionic radius and the highest charge density. Therefore,$BeCl_2$ exhibits the most covalent character and is the least ionic among the chlorides of these alkaline earth metals.

Among the metals $Be$,$Mg$,$Ca$,and $Sr$ of group $IIA$,which one forms the least ionic chloride in the periodic table?
