### Learning Outcomes

On successful completion of this module students should be able to:

1. Describe the structure of the atom and electron energy levels.
2. Compare types of bonds between atoms and molecules, and their relative strengths.
3. Interpret the structures and properties of solids and calculate the effects of stresses on solids.
4. Recognise and apply the thermal properties of solids, liquids and gases.
5. Recall the concept of an ideal gas, apply the gas laws and equation of state.
6. Recognise the effects of heat and work on matter and perform calculations using the First Law of Thermodynamics.

### Brief description

Matter consists of atoms and molecules in solid, liquid or gas phase. The structure and size of atoms - protons, neutrons and electrons are first discussed. Quantisation of energy and ionisation potential. Molecular strcutre is discussed with emphasis on the types of bonding between atoms and molecules. The influences of temperature on the properties of matter is then considered. The behaviour of solids undergoing stress and strain. A simple model of an ideal gas as a collection of hard spheres is shown to lead to an understanding of transport properties of gases and deviations from idela behaviour. Properties of gases are examined from the point of view of the First Law of Thermodynamics.

### Content

Atomic structure - Protons, neutrons, electrons, isotopes and radioactive decay.
