What is a stable isotope?
What is a stable isotope?
A stable isotope is an isotope that does not undergo radioactive decay. The number of protons and neutrons in the nucleus is the same.
What is an unstable isotope?
What is an unstable isotope?
An unstable isotope is an isotope that undergoes radioactive decay, leading to a new element. The number of protons and neutrons in the nucleus are different.

Study Notes
Radioactive Decay
- Stable isotopes do not undergo radioactive decay, with an equal number of protons and neutrons in the nucleus.
- Unstable isotopes undergo radioactive decay, leading to a new element, with a different number of protons and neutrons in the nucleus.
Modeling Radioactive Decay
- Develop simple qualitative models (e.g., pictures or diagrams) to illustrate changes in the nucleus of an atom during radioactive decay.
- Models should demonstrate the energy released during radioactive decay relative to other transformations.
Next Generation Science Standard
- HS-PS1-8: Students can develop models to illustrate changes in the composition of the nucleus and energy released during fission, fusion, and radioactive decay.
