Radioactive decay is random
Some atomic nuclei are unstable. An unstable nucleus releases energy by emitting nuclear radiation, becoming more stable in the process.
Step-by-step lessons on AQA GCSE Physics 4.2.1 Radioactive decay and nuclear radiation. Each one builds up to exam-style questions. Build a strong grip on equations, units and Key Stage 3 fundamentals before tackling the more demanding topics like electromagnetism, the particle model of matter and space physics.
