Alkali metals	Alkaline earth metals
An alkali metals from oxosalts such as carbonate, sulphates and nitrates	An alkali metals from oxosalts such as carbonate, sulphates and nitrates

Alkali metals	Alkaline earth metals
Solubility of carbonates and sulphates increases down the group	Solubility of carbonates and sulphates increases down the group

Alkali metals	Alkaline earth metals
carbonate and sulphates of Li decompose on heating while the stability of carbonates and sulphates of other metals increases down the group.	The carbonates and sulphates of alkaline earth metals decompose on heating but the temperature of their decomposition increases down the group, i.e. their thermal stability increase.
