# What is the trend in hydration entropy of alkali metal ions?

Is there a trend in alkali metal ion hydration entropy?

There's much talk of hydration enthalpy, but I have a hard time finding information about the change in entropy.

Am I right in thinking that Li$$^+$$ would have a more negative $$\Delta S^o_{hyd}$$ than Cs$$^+$$ because more water ligands will be ordered around it, due to it's higher charge density?
