Description:
| Aims: The Unit will provide an introduction to the basics of the nature of the atom, elementary bonding theory, solid-state structural chemistry, periodic trends in main group chemistry and the electronic structure of transition metal compounds.
Learning Outcomes: After studying this unit, students should be able to:
* Name the first 36 elements, their symbols and electronic configurations;
* Name the four quantum numbers and their allowed values;
* Draw radial and angular functions for s, p, d orbitals;
* Describe the bonding in diatomic molecules using molecular orbital (MO) theory;
* Construct MO energy level diagrams and be able to extract chemical information from them;
* Derive the shapes of molecules using the VSEPR method.
Skills: Numeracy (F, A); Problem solving (T, F, A); Oral communication (F).
Content: Bohr model of the atom, quantization, properties of waves, Schrödinger equation and its solutions, angular and radial functions, quantum numbers. The Periodic Table, Aufbau Principle, Hund's Rules; ionisation energy, electron affinity and electronegativity. Molecular orbital theory for homo- and di- atomic molecules.
VSEPR, hybridisation. Coordination chemistry: definitions, shapes, ligand classification, nomenclature and conformations; chelate complexes. Coordination numbers and geometries, isomerism.
