O Level Nuclear Physics with KYM | Lesson 2

What makes an atom radioactive, and how do unstable nuclei become more stable? In Lesson 2 of our O Level Nuclear Physics series, we explore the fundamentals of radioactivity, understand how radiation ionizes matter, and learn how alpha and beta decay change the structure of a nucleus. In this lesson, we cover: Radioactivity and the spontaneous emission of radiation Nuclide notation and representing nuclear changes Ionization and how radioactive emissions interact with matter Alpha decay and changes in proton and nucleon numbers Beta-negative decay and the changes it causes in a nucleus Writing and balancing nuclear decay equations Whether you're learning radioactivity for the first time or revising for your Cambridge O Level Physics exams, this lesson will help you understand nuclear processes and tackle exam questions with confidence. #OLevelPhysics #NuclearPhysics #Radioactivity #AlphaDecay #BetaDecay #Ionisation #NuclideNotation #CambridgePhysics #PhysicsRevision #KYM #KnowYourMomentum
