Episode 523: Preparation for nuclear stability topic

Main aims
Students will:

  • Sketch the N-Z graph for stable nuclei
  • Describe the balance of forces that results in a stable nucleus
  • Calculate mass defect and binding energy
  • Relate nuclear fission and fusion to the graph of binding energy per nucleon

Prior knowledge
Students should know about the composition of nuclei in terms of protons and neutrons. They should be familiar with nuclear notation e.g.

Equation

Where this leads
An understanding of nuclear stability leads on to a study of nuclear fusion and fission.
