  1. Another Look at the Atom Chemistry 4-3 Notes

  2. Line Spectra • Samples of all elements emit light when they are vaporized in an intense flame or when electricity is passed through their gaseous state • The line spectrum for each element is simply the frequency of light given off

  3. Bohr Model of the Hydrogen Atom • Bohr used Rutherford’s planetary model to explain the line spectra of elements • He started with Hydrogen • Each orbital represented an energy level • Each energy level was a quantum • He gave them quantum numbers • N=1 • N=2 • N=3 • Etc.

  4. Bohr Model Animations • Animation 1 • Animation 2 • Animation 3 • Animation 4 • Animation 5 • Animation 6

  5. Matter Waves • De Broglie wavelength

  6. Heisenberg’s Uncertainty Principle
