Part of the Edexcel GCSE Combined Science curriculum.
Edexcel GCSE Combined Science 6 Radioactivity is a step-by-step online learn guide for GCSE students in Years 10 and 11, mapped to the Edexcel specification (Pearson Edexcel GCSE Combined Science (1SC0) – Physics Topic 6 Radioactivity). It covers atoms and isotopes, electrons, energy levels and ions, developing the atomic model, types of nuclear radiation, nuclear decay and equations, activity, half-life and detection and background radiation and radiation safety, then brings it all together with mixed retrieval and exam practice.
There are 23 short steps of about 15 minutes (roughly 6 hours of learning), each made of bite-size explanations with key words, tables and examples, and every bite-size is followed by an activity you check straight away. Key terms include Nucleus, Atomic number, Energy level, Absorption, Plum pudding model, Alpha scattering, Alpha particle, Beta-minus particle, Beta-minus decay, Beta-plus decay, Activity and Becquerel (Bq).
