MgCO3 is thermally less stable than CaCO3.explain why?

caco3 is more stable than mgco3 beacuse thermal stability of carbonates of group 2 will increase down the group with the increase in the size of cation .
this is beacuse longer cation will stabilize the larger carbonate ion .

The thermal stability of carbonate of alkaline earth metal increases down the group. So carbonate of Ca is more stable than carbonate of Mg

CaCo3 is larger in size compared to MgCo3.As we know larger cation can stabilize a larger anion better so obviously Caco3 is more stable than Mgco3

Ionic potential is more then thermal stability is less......we know that ionic potential=cataonic charge/cataionic redius....
mg has less cataionic redius than ca......thus it prooves
