Description
This model can be used to demonstrate the alpha decay of a uranium nucleus. Helium nuclei (alpha particles) can be removed from the nucleus. The sizes of the uranium and helium nuclei are approximately to scale. Assuming a simplified decay chain with no beta decays, the model can undergo four alpha decays to reach a stable isotope of lead.
The V2 files have a cutout in the uranium atom so the alpha particles slide inside of the nucleus.
