Updated for 2025 AQA GCSE Physics and Combined Science (8463 / 8464).
A complete, fully editable lesson covering P7.3 – Changes in the Nucleus from the AQA specification.
Students learn how unstable nuclei decay by emitting alpha, beta, or gamma radiation, how nuclear equations are written and balanced, and how changes in the nucleus affect atomic and mass numbers.
This lesson builds deep conceptual understanding for Paper 1 – Atomic Structure while providing strong exam-practice support through worked examples and structured reasoning tasks.

Includes free AI long-answer feedback – students can submit extended-response questions online and receive instant, AQA-aligned WWW/EBI feedback to improve reasoning, structure, and scientific language.
