Key Questions
Here are some questions to think about before, during, and after this week's experiment:

Why are atomic spectra composed of light emitted in discrete lines rather than in continuous bands?

How are the energy of the light emitted and the energy change of the electron in the atom related?

How are single- and multi-electron atoms different (except in the obvious difference in number of electrons!)? What do the electron energies depend on, in each case?

What is effective nuclear charge? Why is it different for a sodium electron in a 3p orbital and a 3s orbital?

Why do different elements have different spectra?

How do fluorescent lights work? What element or elements do they contain?
