  1. Democritus
    • First person to name "atoms"
    • Indestructable and indivisble
  2. Dalton
    • 4 theories
    • (Atoms combine in whole # ratios)
  3. Thomson
    • Discovered Electron
    • Cookie Dough
    • Cathode Ray Tube
  4. Bohr
    • Planetary model
  5. Rutherford
    • Discovered Positive Nucleus
    • Gold foil experiment

  6. Schrodinger
    • Electron Cloud
    • Jimmy Neutron model
  7. Louis de Boglie
    • Quantom theory
    • wave ~ light
    • particle ~ mass
  8. Neutron
    Atomic mass - Atomic number
  9. Isotope
  10. C = lamda * v
    • C = 3 * 108
    • Lamda = wavelength (m)
    • V = frequency (Hz)
  11. Rays; Shortest/Longest
    • Shortest: Gamma
    • Longest: Radio waves
  12. Atomic Emission Spectrum
    When atoms get "excited", they move up and down energy levels. When moving down, they give off light, called photons which make color.
  13. C
    Lamda | V
    Triangle for equations
