in the case of thermal stability as we move down the group a new shell is going to add in the electronic configuration . 
and after that as new shell adds up , then its very difficult to loose the electron and get degraded as soon as heat provided to the compound . 
also the hydration enthalpy decrease on going down to the group . 
HOPE IT CLEARS NOW
