It is OK to use your textbook or lecture notes from class, but if you can answers the questions without it that is OK too.

Do not press the RETURN or ENTER key while you are answering these questions. Your browser will interpret either the same as clicking on the Submit key.

Answer all of the questions below. If you do not know an answer enter CNA. However, it will help me the most if you answer each question with your best intuition/idea about what would be a reasonable answer.

First Name:

Last Name:


1a. Will an atom absorb or release a photon when an electron moves from the n = 2 level to the n = 4 level?

b) Provide a brief explanation for your response to part a) in terms of the energy of the electron in each level.

2. One of the emission lines in the spectrum of a hydrogen atom has a frequency of 6.91 x 1014 s-1. Using the relationship () calculate the wavelength of this line in nanometers.

3. Calculate the energy required for the electron to move from the n = 3 level to the n = 5 level in a hydrogen atom. Use the relationship we developed in lecture,


4. Is the energy calculated in 3 above smaller, larger or the same as the difference in energy between the n = 2 and the n = 4 level? Explain.

5. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

6. If there is one question you would like to have answered in lecture, what would that question be?
