Lessons designed to build on prior knowledge of nuclear radiation. Covers Alpha & Beta decay and half-life - includes practice questions for students.
Ideal for AQA GCSE (9-1) P4, Cambridge iGCSE P11 and more
Developing: Describe the composition of different nuclei in terms of protons and neutrons.
Securing: State that during alpha or beta decay the nucleus changes to that of a different element.
Exceeding: Use equations involving nuclide notation to represent changes in the composition of the nucleus when particles are emitted.
Developing: Recall that nuclear decay is spontaneous and random.
Securing: Describe what is meant by half life, in terms of number of nuclei and activity.
Exceeding: Calculate half-life from data or decay curves from which background radiation has not been subtracted.
