2. Consider a simplified model of a triply ionized beryllium-9 atom (Be): four protons plus five neutrons in the atom's nucleus, "orbited" by just one electron at a constant distance of 5.75 x 10m. (Note: This is not the actual distance, but it is the correct order-of-magnitude.) (6 pts.) You can solve (a) & (b) in either order. Label your work clearly a. What is the strength (magnitude) of the attractive electric force between the nucleus and the electron? Show...

Example 15.1 The Forces in a Hydrogen Atom Goal Contrast the magnitudes of an electric force and a gravitational force. Problem The electron and proton of a hydrogen atom are separated (on the average) by a distance of about 5.30 x 1011 m. Find the magnitudes of the electric force and the gravitational force that each particle exerts on the other, and the ratio of the electric force, Fe, to the gravitational force, Fo Strategy Solving this problem is just...

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...
