Consider a trial wavefunction for an electron in H atom in the following form º(r) = re-ar where a is an adjustable parameter. Optimize a so that you obtain the minimum energy (i.e., find the extremum by imposing .. (E) = 0). How does the minimum energy compare to the ground state energy of an electron? Hint: n!

5. [25 pts total Consider the H-atom system of an electron freely moving about a nu When solve, looking at this system in spherical coordinates we obtain three differential equations to representing the radial distance (r), axial angle (θ), and azimuthal angle (d) coo rdinates. a) 12 pts] What is the approximation typically invoked to treat this system as just the behavior of the electron motion? Why is it acceptable to do so? b) [3 pts] Sketch a representation of...
