A PowerPoint presentation covering all the topics needed to understand the radioactivity topic in A-level Physics. The content is geared towards the AQA exam board but can work well for other exam boards too.
The presentation clearly explains each topic in a clear and precise way, included images and videos to interact with. There are also practice exam-style questions
The topics included are:
- The discovery of the nucleus
- Alpha scattering experiment
- The maths of the alpha scattering experiment
- Forces involved in the alpha scattering experiment
- Properties (ranges in air, deflection in magnetic field, etc) of alpha, beta and gamma particles
- Ionisation experiment
- Cloud chamber experiment
- Geiger tube experiment
- Absorption and range in air test
- Background radiation
- Radioactive decay
- Activity & power
- Inverse square law
- Nuclear decay formulae
- Rate of decay formulae
- Half-life

- N-Z chart
- Sub-atomic forces
- Decay modes
- Representing decays on N-Z chart
- Distance of closest approach
- Electron diffraction
- Atomic number and nuclear radius
- Gamma radiation (meta-stable states)
- Radioactive dating
