- Explain lattice structures in terms of packing, ionic bonding and energetics, and draw metallic and ionic-derived structures
- Explain aspects of the structure of hydrogenic atoms, including quantum numbers, electron spin, aufbau principles, electronic structure, shielding and penetration
- 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
- Describe the ionic chemistry of groups 1 and 2
- Draw radial and angular wavefunctions, and boundary surface diagrams to describe the shapes of atomic orbitals

Resources & Reading list
C. E. Housecroft and A. G. Sharpe (2018). Inorganic chemistry.
Final exam, tutorials and laboratory marks. The latter are accumulated under the co-requisite lab module.
External repeat only possible if lab module is already passed.
This is how we’ll give you feedback as you are learning. It is not a formal test or exam.Mid-term test
This is how we’ll formally assess what you have learned in this module.
Repeat type: Internal & External
