Calcium ion also has a smaller radius and so a higher charge density giving it a greater polarising power allowing it to distort the bonding In group 1 and 2, the nitrates and carbonates get more stable down the group. Place 2 g of a Group 2 metal carbonate in the test tube and reweigh. Magnesium carbonate (the most soluble one I have data for) is soluble to the extent of about 0.02 g per 100 g of water at room temperature. All group 2 metal ions have the same charge (2+) but the smaller ones at the top of the group have it all packed into a smaller space so they polarise the O-H bond more (pull electrons towards the oxygen). The correct sequence of thermal stability of the following carbonates is : (1) BaCO 3 < SrCO 3 < CaCO 3 < MgCO 3 (2) MgCO 3 < CaCO 3 < SrCO 3 < BaCO 3 (3) BaCO 3 A Level and IB study tools > Chemistry > Thermal stability of group one and two nitrates and carbonates.
