WebApr 12, 2024 · The Thermal stability of alkaline earth metal carbonates increases down the group. Because greater the polarization of the carbonate ion, the easier is to weaken a carbon-oxygen bond in the carbonate and form carbon dioxide and the oxide in heating. ∴ MgCO3 < CaCO3 < SrCO3 < BaCO3. WebSolution. Verified by Toppr. Correct option is A) As we move from top to bottom in a group the size of the alkali metals increases, thereby the bond dissociation energy decreases …
