Group 2 0.0 / 5 ? ChemistryThe Periodic TableASEdexcel Created by: anaortizCreated on: 31-05-17 17:02 Atomic radius Increases as atoms have more energy levels. 1 of 8 Melting points Decrease as the metallic bonding weakens and atom size increases. 2 of 8 Reactivity Increases down the group- 3 of 8 Reactions with water Group 2 metals react with cold water in vigor down the group to form hydroxides. 4 of 8 Solubility of hydroxides Become more soluble down the group. 5 of 8 Solubility of sulphates Less soluble down the group 6 of 8 Carbonates The ease of thermal decomposition decreases down the group. They're more thermally stable down the group. 7 of 8 Nitrates Ease of thermal decomposition decreases down the group. 8 of 8
