Reading Review Notes for Week 8:

-What are the four quantum numbers for an atom.  

-Compare Y and R with Y from the electron in a box case.

-What is the Bohr atomic radius?  Using figures in the  text, determine this value for 1s, 2s, and 2p.

-How does the voltage potential change for atoms other than H?

-How do you know the formation of H2 is favorable?

-What is the LCAO method?

-Study Fig. 4.2. Which state is more likely to have electrons in it?

-Why is He2 unlikely?

-What is a node and why does a wavefunction have higher energy if it has more "nodes"?

-Explain the difference between the band being full to the half-energy point and half the energy states being full.  Which one is correct?

-What is the Fermi energy?  It is measured with respect to what?

-Compare this sections work function with the one we talked about in the photoelectric effect.  Are they the same?

-Describe sp3 hybridization.

-Why is YB less than YA in Fig. 4.17?

-What is a hole and how is it made?

-What is the difference in band structure between a metal and a semiconductor?

-Why is the line n'2 sketched in Fig. 4.21 and 4.22?

-Where does the 1/8 term come from in the equation on the bottom of page 260?

-Follow the derivation of Eq. 4.9.  Make sure you understand each step.

-Use Eq. 4.10 to explain Fig. 4.20.
