Activity 3 1/20/2011 Gas excitation spectra

Make observation of excited state of gas.
Tubes with different gases creates different colors. The orange is created by neon lights. When putting on the glasses I see a strip of light of multiple colors around the light. There are a total of seven spectrums. With the different gas that creates a white light I'm seeing the same thing, except there are 8 spectrum lights this time. That one was helium. This one is a purple light and I'm seeing nothing.. I had to move to get closer and saw a line strip. Carbon dioxide is a light blueish color and with the glasses it creates thin spectrum that are different from the others.

With neon there are 10 protons and 10 electrons so this is why we see more light.
