Lattice Energy - Decomposition of Group II carbonates The ease decomposition of Groups II carbonates is determined mainly by the size of the metal ion. The smaller the size of the ion the more polarizing the ion is. That is, the metal ion interacts with the electrons in the carbonate ion, destabilizing the bonds leading to the formation of the metal oxide and carbon dioxide gas.
