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.
