Alpha Decay
This simulation has not been translated into this language. You can still access the English version below.
Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life.

Sample Learning Goals
- Explain what happens in alpha radiation.
- Predict what happens to an element when it undergoes alpha decay.
- Explain the concept of half life, including the random nature of it.
- Begin to gain an understanding of the forces that work to hold an atomic nucleus together (strong nuclear force) and the forces that work to break it apart (Coulomb, i.e. electric charge, force).
Tips for Teachers
