- Neon Emission Spectrum
A. Based on the emission spectrum for neon, what color would youpredict 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 dischargetube?_________________________________________________________
- Sodium Emission Spectrum
A. The most prominent line in the emission spectrum of sodium isthe result of a transition from a 3p to a 3s orbital. Thewavelength of this line is 5893 Ã…. Convert this to nanometers (showyour calculation) and give the color of light corresponding to thiswavelength.
B. Based only on the color of the lines corresponding to thetransitions, is the sodium 3p  3s transition of higher or lowerenergy than the n=3  n=2 transition in the hydrogen atom?Explain.
