-
Alkali metals Alkaline earth metals All alkali metals except Li form ionic compounds All alkaline earth metals except Be form ionic compounds -
Alkali metals Alkaline earth metals The solubility of oxides of alkali metals increase down the group The solubility of oxides of Mg, Ca, Sr and Ba. BeO, however, is covalent and insoluble in water -
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.
