Question
Suppose you are given a chance to repeat the alpha-particlescattering experiment using a thin sheet of solid hydrogen in placeof the gold foil. (Hydrogen is a solid at temperatures below 14 K.)What results do you expect?
Solution
If we were to repeat the alpha-particle scattering experiment using a thin sheet of solid hydrogen instead of the gold foil, we can expect different results. Here are the steps to consider:
-
Preparation: Obtain a thin sheet of solid hydrogen and ensure it is at a temperature below 14 K to maintain its solid state.
-
Setup: Set up the experimental apparatus similar to the original alpha-particle scattering experiment. This includes a source of alpha particles, a detector, and a target material (in this case, the thin sheet of solid hydrogen).
-
Alpha particle scattering: Fire the alpha particles towards the thin sheet of solid hydrogen and observe their scattering patterns.
-
Analysis: Analyze the scattering patterns to determine the behavior of the alpha particles as they interact with the solid hydrogen.
Based on the properties of solid hydrogen, we can expect the following results:
a) Size of the nucleus: Since hydrogen has a single proton in its nucleus, the size of the scattering center will be significantly smaller compared to the gold foil used in the original experiment. This means that the alpha particles will have a higher chance of interacting with the nucleus of the hydrogen atoms.
b) Scattering angles: The scattering angles of the alpha particles will depend on the interaction between the alpha particles and the hydrogen nuclei. The smaller size of the hydrogen nucleus may result in larger scattering angles compared to the gold foil experiment.
c) Number of deflections: Due to the smaller size of the hydrogen nucleus, we can expect a higher number of deflections or scattering events compared to the gold foil experiment. This is because the alpha particles will have a higher chance of coming close to the hydrogen nuclei and experiencing a scattering event.
Overall, conducting the alpha-particle scattering experiment with a thin sheet of solid hydrogen will provide insights into the interaction between alpha particles and hydrogen nuclei. The results may differ from the original gold foil experiment due to the differences in the size and properties of the scattering material.

In Rutherford's famous experiment, he shot heavy, fast moving, positive alpha particles at a thin gold foil. Based on Thomson's plum pudding model of the atom, what did Rutherford expect to happen, and why? All the alpha particles would be deflected by the foil because of the even distribution of mass and charge throughout the atom. All the alpha particles would pass straight through the foil because of the even distribution of mass and charge throughout the atom. Most of the alpha particles would become embedded in the foil because they are attracted to the negative electrons in the atom. Some of the alpha particles would be deflected and some would pass through because of the negative charge of the electron cloud.
