the stability of alkali chlorides increases down the group as the size of cations and anions are matchable and hence their packing becomes more strong and they become more stable.

 

    therefore stability order is   CsCl  >RbCl >  KCl  > NaCl > LiCl

alkali chlorides are extra stable due to high electrostatic interaction.electrostatic forces are considerd one of the most strongest forces in the universe and are ranked second after the nuclear forces now ,

 

as the alkali metal has a high potential (highest) to loose an electron and the halogens have the highest electronegativitty so they tend to attract each other strongly.
