Chapter 15.4
The Nucleus: Radioactive Decay, Fission, and Fusion
A nucleus weighs less than the protons and neutrons that make it, and that missing mass is the energy holding it together. Release a little of it and you have a star, or a bomb.

By the end
- 01Apply conservation of nucleon number, charge, and lepton number to alpha, beta, and gamma decay
- 02Describe the strong force and use mass–energy equivalence in fission, fusion, and decay
- 03Use half-life and exponential decay to predict what remains of a sample, or its age
