Alfa raspad
|
Java via CheerpJ:
We've partnered with Leaning Technologies to allow our Java sims to run in a browser.
This sim is not compatible with iPads.
Java Version:
Supports offline use and offers improved performance.
Teme
- Alfa raspad
- Poluživot
- Radijacija
Opis
Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life.
Uzorak ciljeva učenja
- 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).
