Using Table 5.2, write down the mathematical expression for the 2px wave function for an electronically excited H atom. Estimate the probability of finding the 2px electron if you look in a cubical box of volume of 0.8(pm)3 centered at a distance of 0.5001010m in the =/2 , =0 direction. Does this probability change as you change ? At what angles is the probability of finding the electron smallest and at what angles is the probability the largest? (Note that =2 is the same location as =0 , so don’t double count.)
A particle of mass m is placed in a three-dimensional rectangular box with edge lengths 2L, L, and L. Inside the box the potential energy is zero, and outside it is infinite; therefore, the wave function goes smoothly to zero at the sides of the box. Calculate the energies and give the quantum numbers of the ground state and the first five excited states (or sets of states of equal energy) for the particle in the box.

For the Li atom, the energy difference between the ground state and the first excited state, in which the outermost electron is in a 2p orbital, is 2.961019J . In the Li2+ ion, the energy difference between the 2s and 2p levels is less than 0.00002 of this value. Explain this observation.

Write the set of four quantum numbers that describes an electron in a 3d orbital. Report your answer in the following format (2, 1, -1, +1/2).

Only certain electron transitions are allowed from one en-ergy level to another. In one-electron species, the change in the quantum number l of an allowed transition must be ±1. For ex-ample, a 3p electron can drop directly to a 2s orbital but not to a 2p. Thus, in the UV series, where nfinal1, allowed electrontransitions can start in a porbital (l=1) of n=2 or higher, notin an s(l=0) or d(l=2) orbital of n=2 or higher. From whatorbital do each of the allowed electron transitions start for the first four emission lines in the visible series (n(final=2))?
