1. Atomic Emission Spectrum Make-Up Lab
Observe the atomic emission spectra for several elements.
Answer the questions that follow on a piece of notebook paper titled “atomic emission spectrum make-up lab”

2. Emission Spectrum

3. Argon

4. Neon

5. Krypton

6. Copper

7. Potassium

8. Magnesium

9. Chlorine

10. Oxygen

11. Emission spectrum Vs. Absorption spectrum
All colors in absorption spectrum are absorbed; dark lines represent frequencies of light that are absorbed
Colored lines in emission spectrum represent colors that are emitted; dark sections represent frequencies that are absorbed

12. Questions
1. What evidence is there that electrons move around in definite pathways around the nucleus?
2. Which color represents the most energy, red or blue? Explain.
3. What do the dark areas in the emission spectrum represent?
4. How is the absorption spectrum and emission spectrum related? 5. Are the colors seen produced during absorption or emission of energy by the electrons? Explain.
