This resource is a complete teaching presentation that explores the structure, stability, and transformations of atomic nuclei. It provides clear explanations, worked examples, graphs, and exam-style questions to help students master this core topic.
The resource includes:
- Atomic structure and particles in nuclear reactions, including balanced nuclear equations.
- Mass defect and binding energy – definitions, calculations, and their link to nuclear stability.
- Energy–mass equivalence (E = mc²) – applications with electron volts (eV) and mega-electron volts (MeV).
- Binding energy per nucleon – graphs, trends, and nuclear stability, with examples of iron and uranium.
- Nuclear fusion and fission – processes, worked examples, and energy release explanations.
- Radioactivity – types of decay (α, β, γ), nuclear transmutation, and practical applications.
- Decay constant, activity, and half-life – equations, exponential decay, and example problems.
- Detection of radiation – using Geiger–Müller tubes and activity measurements.
- Worked examples, quizzes, and exam-style practice questions to reinforce understanding.
This resource can be used by teachers as a lesson presentation, problem-solving toolkit, or revision guide, and by students for self-study and exam preparation.
