IGCSE Physics | Radioactive Decay Explained | Lesson 45

Learn the key concepts of Radioactive Decay in this IGCSE Physics lesson. In this video, we explain why unstable nuclei decay, how radioactive emissions change the nucleus, and how decay can be represented and interpreted in typical IGCSE Physics exam questions. 📚 Topics covered: Radioactive decay Unstable nuclei Alpha decay Beta decay Gamma emission Changes in atomic number and mass number Random nature of radioactive decay Decay curves Half-life Common exam question types Key exam tips This lesson is ideal for students preparing for Cambridge IGCSE Physics who want to strengthen their understanding of radioactivity and nuclear physics and become more confident with decay and half-life questions. 📘 Looking for more structured IGCSE resources?
