as we know latice energy is directly proportional to ionic chracter
by the concept of latice enery CsCl is is less stable than NaCl
but Cs ic most electropositive element and Cl is most electronegitive element
than the CsCl must be more ionic than Nacl

Here we would check ionic character via size difference.
CscL has less size difference therefore more covalent character and less ionic character than NaCl.
In NaCl size difference is maximum and therfore less covalent character and more ionic character.
