ATOMS AND QUANTA - 2022/3

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.

Assessment pattern

Alternative Assessment

Assessed Laboratory Diary Mark and Report/Poster UoA may be assessed by two laboratory experiments, two diaries and two written reports.

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 written examination of 2-hour duration with a series of short compulsory questions, and a section of longer questions with a choice of 2 out of 3. 
  


• 
  Bi-weekly hand-in questions from Small Group Tutorial Sessions
  


• 
  A laboratory diary mark on selected experiments (continuous assessment)
  


• 
  EDI Awareness Engagement
  

 

 

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.

The Laboratory unit of assessment has a qualifying mark of 40%.

The assessment of engagement with the EDI Awareness Workshop will be by an open book quiz with unlimited re-attempts, but it must be passed in order to pass the module.

 

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.

Learning outcomes

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 
  


• 
  laboratory classes, spread through the semester
  

 

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
