Module overview

This module identifies the new theories necessary to describe physical processes when we go beyond the normal speeds and sizes experienced in everyday life. A review of new phenomena that led to the development of quantum theory follows naturally into an introduction to the theory of atomic structure. Along the way, the Schrödinger equation is introduced and elementary applications are considered. Several important aspects of the structure and spectroscopy of atoms are considered in detail.

The basis is laid for the study of the properties of matter in more detail at higher levels.

Module aims

provide an understanding of the principles underlying elementary quantum theory and their experimental foundation.

develop quantum principles so that the meaning and the use of the Schrödinger equation can be appreciated.

instill a knowledge of the shell and orbital structure of atoms, and key effects such as fine structure.

provide a broad foundation for further studies of atomic, nuclear and solid state phenomena,

provide an introduction to spectroscopic notation and angular momentum coupling.

via the laboratory, reinforce concepts from lectures. The aims of the laboratory are to build on the foundation of previous practical classes when conducting experiments to verify theory and to improve understanding. Another aim is to develop skills in analysing data. The importance of keeping a laboratory notebook (diary) and the clear presentation of results will be stressed.

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

equip students with subject knowledge

develop skills in applying subject knowledge to physical situations

develop practical laboratory skills

The learning and teaching methods include:

lecture-based classes with accompanying tutorials as 3h/week for 11 weeks

laboratory classes 20h overall, spread through the semester

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

recall of subject knowledge

ability to apply individual components of subject knowledge to simple problems

ability to synthesise and apply combined areas of subject knowledge to complex problems

competence in undertaking and analysing experimental work

Thus, the summative assessment for this module consists of:

A laboratory diary mark (continuous assessment)

A laboratory report mark (end of semester)

a 2h final examination with 5/5 short questions to be answered, and 2/3 longer questions to be answered

Formative assessment and feedback

Verbal feedback will be given in tutorials, and during the laboratory sessions. Written feedback will be given when marking the lab diary.
