EL – Section 2 – (e), (f), (i), (j), (k), (m), (n), (v), (w) Next, looking at how we study the radiation we receive from outer space provides the context for discussion of atomic spectroscopy and electronic structure. A historical approach is used to introduce the periodic table, including the links between electronic structure and physical properties. This is followed by studying some of the molecules found in space, providing the context for introducing bonding and structure and the shapes of molecules. 14 hours out flame tests with compounds containing appropriate ions – for example . Atomic and molecular structure provides opportunities for building and discussion (HSW1, 8). Explanation of atomic spectra in of electron transitions and the use of ‘dot-and-cross’ diagrams in explaining molecular shape provide opportunities for discussing development of scientific arguments (HSW2). Deducing electronic configurations through identification of relationships between ionisation enthalpy and atomic number provides opportunities for analysis and interpretation of data (HSW5). Main chemical ideas: Atomic spectra and electron configuration; the periodic table and Group 2 chemistry; Bonding and shapes of molecules. 2.8.8 notation is no longer required. Detailed discussion of atomic and electronic structure, including s and p orbital shapes, are studied here. The electrostatic nature of covalent bonding and lone pair effects in molecular shapes are now discussed. Giant metallic, ionic and covalent-lattice structures are introduced. Flames tests are included. Knowledge of the EM spectrum from infrared to ultraviolet is required, and use of both c = and E = h. Group numbers now following (1 to 18), i.e. halogens are referred to as Group 17 and noble gases as Group 18.
