Chemistry STPM Sem 2 - Chapter 4 Group 2

10 Group 2	Candidates should be able to:
10.1 Selected Group 2 elements and their compounds	(a) describe the trends in physical properties of Group 2 elements: Mg, Ca, Sr, Ba; (b) describe the reactions of Group 2 elements with oxygen and water; (c) describe the behaviour of the oxides of Group 2 elements with water; (d) explain qualitatively the thermal decomposition of the nitrates, carbonates and hydroxides of Group 2 elements in terms of the charge density and polarisability of large anions; (e) explain qualitatively the variation in solubility of sulphate of Group 2 elements in terms of the relative magnitudes of the enthalpy change of hydration for the relevant ions and the corresponding lattice energy.
10.2 Anomalous behaviour of beryllium	(a) explain the anomalous behaviour of beryllium as exemplified by the formation of covalent compounds; (b) describe the diagonal relationships between beryllium and aluminium; (c) explain the similarity of aqueous beryllium salts to aqueous aluminium salts in terms of their acidic property.
10.3 Uses of Group 2 compounds	(a) state the uses of Group 2 compounds in agriculture, industry and medicine.
