External repeat only possible if lab module is already passed.
Aims and Objectives
Knowledge and Understanding
Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:
- Calculate lattice parameter, distances between ions, packing density and gravimetric density of ionic solids
- Use Lewis structures and VSEPR to explain bonding, geometry and shapes in molecules and ions
- Explain aspects of the structure of hydrogenic atoms, including quantum numbers, electron spin, aufbau principles, electronic structure, shielding and penetration
- Construct molecular orbital energy level diagrams for homo- and heterodiatomic molecules
- Describe the ionic chemistry of groups 1 and 2
- Explain lattice structures in terms of packing, ionic bonding and energetics, and draw metallic and ionic-derived structures
- Draw radial and angular wavefunctions, and boundary surface diagrams to describe the shapes of atomic orbitals
- Assign symmetry elements and point groups to molecules and ions
