Radioactive Decay and Particle Interactions

Start with atomic structure

Begin with the mind map Particle Physics for an overview of atomic structure, nuclide notation and alpha particles. It also includes Rutherford’s alpha-scattering experiment. The flashcards in AS Physics Radioactivity cover the scattering experiment alongside nucleons, isotopes and notation.

Use the map to see the ideas together, then use the flashcards to check the terms you remember. Return to the map when a term needs more context.

Move on to nuclei and decay

The page includes a Matter and Radiation mind map on stable and unstable nuclei, alpha decay, beta decay and the strong nuclear force. Another mind map, Physics - Matter and Radiation, also brings together atoms, nuclei, the strong nuclear force and radioactive decay.

After looking at atomic structure, follow these maps to see how the resources connect nuclei with decay. You can then use the Particles flashcards to practice terms such as isotope, nucleon and nuclide, as well as questions about the strong nuclear force.

Use the quiz alongside a map

The page also has a quiz. Try it after studying a map or flashcard deck, and use your answers to decide which material to look at again. A map can help you see related ideas together, while flashcards offer individual questions and terms to practice.

Explore the unit

Radioactive Decay and Particle Interactions is a section of the Particle Physics unit in Physics. The resources on this page bring atomic structure, particles and radioactive decay together within that unit. Pick a map or flashcard deck and build a study sequence that suits you.
