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. To be clear, the negative charge in the sphere was proposed to be spread through the volume of the sphere, not on its surface. Z is the atomic number. (a) In terms of the symbols, Z and R, what is the...
both parts pls 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...
The correct answers are already given. What you have to do is how to get those answers. Problem 1: An early model of the atom, proposed by positive point charge +Ze (the nucleus) at the center of a sphere of radius R with uniformly distributed negative charge -Ze. Zis the atomic number, the number of protons in the nucleus and the number of electrons in the negative sphere after his discovery of the atomic nucleus, had a a. Show that...
Part A 1 Review Show that the electric field strength inside this atom is Ein = (1 ) 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. $Ē...
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...
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. Thank...
A simple model of an atom is one that starts with a point nucleus of charge +q/ That nucleus is then surrounded by a concentric charged cloud of radius a containing a total negative chrage -q, distributed unifromly through its volume. Using Gauss's law determine the electric field E for r<a using gauss's law determine the electric field E for r>a
BONUS: Electron Cloud In the Bohr model of hydrogen, the electron is treated as a point particle orbiting the nucleus at a distance of Og . 5.3. 10-11 m Reality is not so simple, however. The charge of the electron is distributed around the nucleus in a spherically symmetrie, nonuniform manner. (ais merely the most probable distance between the electron and the nucleus.) In this problem, we will explore the electric fields within a hydrogen atom using Gauss' law. Treat...
ANSWER BOTH 1 AND 2 PLEASE!!!!!! Quiz (for extra credits, open notes) Name and G-id 1. Two charges are placed on the x-axis: a positive charge +O at x- -d and a negative charge-Q at x = d. Derive the expression for the electric field (magnitude and direction) at any point on the y axis (show work in detail). atx--dand a 2. A positive charge +Q is uniformly distributed on a spherical surface of radius R. In addition, in the...
2. (10 points) The English physicists J.J. Thompson proposed a model in which the atoms consisted of a sphere of positively charged material into which were embedded negatively charged electrons. Consider such an atom consisting of one electron of mass m, having a charge -e which is considered as a point charge, embedded in a sphere having total charge e uniformly distributed over a sphere of radius R a) Find the nuclear electric field inside and outside the sphere. (Ignore...
