Chemistry

• First person to name "atoms"
• Indestructable and indivisble

• 4 theories
• (Atoms combine in whole # ratios)
• 

• Discovered Electron
• Cookie Dough
• Cathode Ray Tube
• 

• Planetary model
• 

• Discovered Positive Nucleus
• Gold foil experiment

• Electron Cloud
• Jimmy Neutron model
• 

• Quantom theory
• wave ~ light
• particle ~ mass

Atomic mass - Atomic number

• C = 3 * 10⁸
• Lamda = wavelength (m)
• V = frequency (Hz)

• Shortest: Gamma
• Longest: Radio waves

When atoms get "excited", they move up and down energy levels. When moving down, they give off light, called photons which make color.
