- Neon Emission Spectrum

A. Based on the emission spectrum for neon, what color would you predict for the neon tube? ______________________________

B. Search on Google for an image photo of a neon spectrum tube. Was your prediction correct? ____________________________

C.What is responsible for the color of a neon discharge tube?_________________________________________________________

- Sodium Emission Spectrum

A. The most prominent line in the emission spectrum of sodium is the result of a transition from a 3p to a 3s orbital. The wavelength of this line is 5893 Å. Convert this to nanometers (show your calculation) and give the color of light corresponding to this wavelength.

B. Based only on the color of the lines corresponding to the transitions, is the sodium 3p  3s transition of higher or lower energy than the n=3  n=2 transition in the hydrogen atom? Explain.
