Review Part B An early model of the atom, proposed by Rutherford after his discovery of the atomic nucleus, had a positive point charge +Ze (the nucleus) at the center of a sphere of radius R with uniformly distributed negative charge -Ze. Z is the atomic number, the number of protons in the nucleus and the number of electrons in the negative sphere. What is E at the surface of the atom? Give your answer as a...

In the early part of the 20th century, Sir Joseph J. Thomson (discoverer of the electron) proposed a "plum pudding" model of the atom. He believed that the positive charge of the atom was spread out like a pudding and that the negative charges (electrons) were embedded in the pudding like plums. His student Ernest Rutherford performed an experiment in 1911 that disproved the plum pudding model. Rutherford fired a beam of alpha particles (helium nuclei) at a thin metal...

In class we discussed a simple model for an atom, in which a cloud of negative charge (the electrons) surrounds a fixed nucleus of positive charge. Develop the details of this model as follows: Suppose an atom has one electron with charge -e and a ucleus of charge e 1.6 x 10-19 C, and the electronic charge is uniformly distributed over a sphere with the Bohr radius a0 4 E0n°/(me2) 5.29% 10-11 m If the electron cloud is displaced a...

For a while in the early 20th century one proposed model for the structure of atoms was that a positive point charge (the nucleus) +Ze was at the center of a charged sphere of radius R and charge −Ze.

If the electron were displaced from equilibrium by a distance
greater than R, would the electron oscillate? Would its motion be
simple harmonic? Explain your reasoning. (Historical note:
In 1910, the atomic nucleus was discovered, proving the Thomson
model to be incorrect. An atom's positive charge is not spread over
its volume as Thomson supposed, but is concentrated in the tiny
nucleus of radius 10^−14 to 10^−15m.)
Any solution with an explanation for this question would be
greatly appreciated.
