hi

1)carbonates:increases down the group. 

 

Li2CO3<Na2CO3<K2CO3<Rb2CO3<Cs2CO3

 

2)halides:increases down the group.

NaCl<KCl<RbCl<CsCl

 

3)sulphates:increases

Li2SO4<Na2SO4<K2SO4<Rb2SO4<Cs2SO4

 

4)hydroxides:increases

 

almost stability of all the cpds(including bicarbonates and peroxides) increases down the group.

hope this helps

rate if u find it  useful
