Rutherford's scattering experiment

Rutherford’s scattering experiment is also known as the gold foil experiment. This experiment disproved the plum pudding model of J.J. Thomson. In a gold foil experiment, high-energy alpha particles are made to strike a thin gold foil. The scattered alpha particles are detected using a detector. This experiment showed that the positive charge of the atom is at the center. Most of the atom’s mass is also confined to a small volume at the center. This region is known as the nucleus of the atom.

Solve using GUESS method. Atomic and Nuclear Phenomena 1. A hypothetical atom has three energy levels with consecutive levels differing by 1 eV. Find the frequency and wavelength that this atom can emit when going from an excited state to a lower energy state.
2. The atomic nucleus may be a sphere of a positive charge, with a diameter very much less than that of the atom. Discuss the experimental evidence which supports this view.
4. The energy of the atom is in part determined by the electrical potential energy of the electron interacting with the proton nucleus, and when the electron is close to the nucleus it is very tightly bound. That's why the energy is negative, and larger in magnitude the smaller n. What does this tell you about the size of the atom for large n? Explain your reasoning.
Question 1 a) The diagram below shows a plan view of the apparatus used by Rutherford and his team which led them to proposing the nuclear model of the atom. Travelling microscope with phosphorescent screen Gold foil Alpha source in lead collimator Describe how the apparatus was used to probe the microscopic structure of matter. [Suggested word count 150] b) Whilst the vast majority of alpha particles passed through the gold foil with little or no deviation, a small fraction of them were scattered through larger angles, some even backwards. Commenting on these findings Rutherford wrote “It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you.” Explain the implications of Rutherford’s results for models of atomic structure.
