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...

3. 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...

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...

2. In the derivation of the energy levels in the hydrogen atom one commonly assumes that the nucleus is a point charge. However, in reality the size of the nucleus is of the order of Im = 10-15m. Since this is very much smaller than the typical distance of the electron from the nucleus, which is of the order of a0-0.5A = 0.5 × 10-10m, the finite size of the nucleus can be taken into account perturbatively.

3) (30 points) A hydrogen atom can be modeled as a point charge nucleus surrounded by a "cloud" of electrons. From our point of view the cloud represents the charge distribution of the electron which is not a point but a smeared out spherical chunk of charge. Let the central charge have a charge of +le] = 1.6x10- Coul. The rest of the charge distribution looks like: (use a = 0.10 nm which is...

A hydrogen atom consists of a proton, effectively a point charge of +1.6 × 10^-19C, surrounded by a spherical “electron cloud” of radius 5.3 × 10^-11m and charge −1.6 × 10^-19C. Use Gauss’s Law to find the electric field at a point (a) 2 × 10^-11m from the proton (inside the atom) and (b) 1 × 10^-10m from the proton (outside).
