The ions in a compound attract each other, and the water molecules attract the ions.
if the water molecule attract the ions in the compound than ions have for each other, then the compound will be soluble in water.
so larger the size of ions lesser will be the attraction bitween them so greater will be the solubility in water
for example Cs is in 6th period and Na and Cl in the 3rd period, so size differance maximum in CsCl hence it is more soluble than NaCl
