Episode 523: Preparation for Nuclear Stability Topic
Produced by the Institute of Physics, the learning episodes in this topic prompt students to consider why some nuclides are stable while others are unstable or radioactive. Starting from the pattern of stability, this section looks at forces in the nucleus and the idea of binding energy.
There are two learning episodes:
Episode 524: Stable nuclides
Episode 525: Binding energy
After completing the activities, students should be able to:
1. sketch the N-Z graph for stable nuclei.
2. describe the balance of forces that results in a stable nucleus
3. calculate mass defect and binding energy
4. relate nuclear fission and fusion to the graph of binding energy per nucleon.
