Hydration enthalpy

Ag+ has a more exothermic enthalpy of hydration than Na+ but has a larger ionic radius. Suggest an explanation for this

Hey! I think this answer here can help you understand it better: thermodynamics - Why does silver (I) have a larger lattice enthalpy and hydration enthalpy than sodium? - Chemistry Stack Exchange

@SaqibKhan Hey!
The silver ion is larger and can have more interactions at the same time. statistically more water molecules fit around a larger ion.
