Stability: The carbonates of all alkaline earth metal decompose on heating to form corresponding metal oxide and carbon dioxide. The Facts. This can be reasoned as such - The charge density of metals at the top is higher than those at the bottom, so they attract the "normal" oxide ion with a much higher force which doesn't give it enough time to combine with another oxygen atom to form a peroxide, so they prefer to form normal oxides, but when we go down the group, like in sodium the charge density becomes lower so it doesn't attract the oxide ion with as high force and thus allows it to combine with another oxygen atom. 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..
