1rohit, what if we consider a gasous Li + ion ? now, enthalpy of hydration comes into count ?
THE IONISATION ENERGIES OF GROUP 1 METALS SUGGEST THAT Cs(CESIUM) SHOULD BE MOST REACTIVE ,BUT THE STANDARD ELECTRODE POTENTIALS SHOW THAT Li(LITHIUM) IS THE MOST REACTIVE......RECONCILE THESE OBSERVATIONS

1Li having the higest hydration energy becomes the most reactive....read it from JD LEE
1Li being very small in size has almost two layers of hydration hence havin very high hydration energy....n so the high ionisation energy is overcome by the amount of energy released wen it is hydrated////
