Bright Line Emission Spectrum

2. Color in the full color spectrum as shown below…. ROY G. BP 

3. Hydrogen
This is what pure hydrogen gas looks like when the atoms gain energy and their electrons fall back to ground state.

4. When the light is looked at through diffraction grating, the light separates out into different bright line colors. On your lab sheet, color in the two very bight lines and the dimmer lines that are present in the highlighted box.

5. Helium

6. Colors in the spectrum as seen through diffraction grating
Colors in the spectrum as seen through diffraction grating. Notice that the bright lines are different than those of hydrogen. On your lab sheet draw in the bright line spectrum.

7. Neon

8. Color in the spectrum as seen through diffraction grating

9. Air

10. Color in the spectrum as seen through diffraction grating

11. You should be able to identify the next element based on the spectra you have already seen.
Color in this element’s spectrum and identify the element based on the bright line spectra.
Then answer the questions on the back of the lab and turn it in.

12. Who am I?

13. The end
