Detailed Solution for Major Inorganic Chemistry - Question 9

As we move from top to bottom in a group the size of the alkali metals increases, thereby the bond dissociation energy decreases hence it requires less energy to decompose so thermal stability also decreases..
So the order of thermal stability of IA group elements is 

LiH > NaH > KH > RbH.
