Part I Instructions (Alpha Decay): Go to the following website: Rutherford Scattering . When the new window pops up, click on the play button to open the simulation. . Once the simulation opens, click on the Rutherford Atom. Scattered Particles Most particles are undeflected Beam of Thin gold particles Foil Circular flurescent Source of Screen O particles Rutherford Atom Once open, set the number of protons to 20 and click on the blue button above the Alpha Particles to start firing Alpha particles towards the gold foil. 1. Click on the Traces button. What do you notice about the paths of most of the alpha particles? 2. Increase the number of protons to 60. Does it change how the alpha particles move? If so, how? 3. Now, increase the number of protons to 100. How does this increase change how the alpha particles move through the gold foil as compared to when you started? Why do you think this change occurred? 4. Repeat the above steps, but vary how many neutrons are present with the protons. Does this change how the Alpha particles travel? 5. Click on the red/gray sphere and reset the number of protons to 20. Watch and describe how the alpha particles move in relationship to the nucleus. 6. Click on the red/gray sphere and reset the number of protons to 60. Watch and describe how the alpha particles move in relationship to the nucleus
