  1. Experiment 8.6Flame Test of Some Elements

  2. Flame Test:A characteristic color pattern is given off by certain metallic elements as they are heated in a flame.

  3. Flame Test:A characteristic color pattern is given off by certain metallic elements as they are heated in a flame. No two elements have the same spectrum;

  4. Flame Test:A characteristic color pattern is given off by certain metallic elements as they are heated in a flame. No two elements have the same spectrum; therefore the color can be used to identify the metals.

  5. Which elements are we going to look at?

  6. Which elements are we going to look at?Lithium, Sodium, Potassium (Group I Family)

  7. Which elements are we going to look at?Lithium, Sodium, Potassium (Group I Family)Calcium, Strontium (Group II Family)

  8. Which elements are we going to look at?Lithium, Sodium, Potassium (Group I Family)Calcium, Strontium (Group II Family)Copper (Transition Metal)

  9. Why does this happen?

  10. Why does this happen?The electrons in the outer shell are “excited” by the energy received from the flame.

  11. Why does this happen?The electrons in the outer shell are “excited” by the energy received from the flame. This causes them to be raised to a higher energy level.

  12. Why does this happen?The electrons in the outer shell are “excited” by the energy received from the flame. This causes them to be raised to a higher energy level. When the electrons fall back to their normal energy levels, the extra energy is given off in the form of light.
