Similarities and trends in the properties of the Group 2 metals, magnesium to barium, and their compounds
What this topic asks you to be able to do
- describe and explain qualitatively the trend in thermal stability shown by the nitrates and carbonates, including how ionic radius affects how strongly the large anion is polarised
- describe and explain qualitatively how, for the hydroxides and sulfates, solubility and the enthalpy change of solution, ΔH⦵sol, vary, in terms of how large the lattice energy is compared with the enthalpy change of hydration
