Reading Review Notes for Weeks 6 & 7:

• Re-read the notes from last class. 

-What is the difference in E and k that is allowed for a free electron versus an electron in a box?

• Things to think about

-What would happen to an electron in a box if light was shone on it?  if it was heated up?

-What happens to the energy levels if you make the box big (make a big)?

• Read sections 3.7-3.8

-How does H, He+, Li+++ differ?

-What do n, l, and m represent?

-What does s, p, d, and f stand for?

-Study Fig. 3.21.  What is the difference between a and b?  For each electron, what is the most probable location for an electron?

-What is the difference between Fig. 3.21 and 3.22?

-Compare Eq. 3.37 a and b with 3.17.  How does the value of E change between the levels fro each?  Why?

-Define excitation, emission, and absorption.

-Describe what the Bohr radius is.

-What is the angular momentum of an electron in the ground state?

-What is the selection rule and why do we have it?

-Why in example 3.15 are those wavelengths dark?

-How does the allowed quantized values of m_s differ from n,l, and m_l?

-Compare Eq 3.44/3.45 with 3.42/3.43 and 3.39/3.40.

-How does the energy of 4s compare to 3d?
