Which is not correct for covalent character?

Covalent character is inversely correlated with cation size and directly proportional to charge. As a result ${\mathrm{ZnCl}}_2$ and ${\mathrm{CaCl}}_2$ are more covalent than AgCl because they have a +2 charge on the cation compared to AgCl's +1 charge. The size of zinc is less than that of cadmium. This makes it more divisive 

${\mathrm{CaCl}}_2>{\mathrm{ZnCl}}_2$ (covalent character)
