1. Louis deBroglie The electron moves through space as an energy wave.
In order to understand an atom, we need to understand the behavior or electromagnetic waves

2. Electromagnetic Spectrum Video

3. Long Wavelength =
Low Frequency
Low Energy
Short Wavelength =
High Frequency
High Energy

4. Electromagnetic Spectrum

5. Electron Transitions
Electrons transitions involve jumps with definite amounts of energy
This produces bands
of light with definite wavelengths.

6. Flame Tests
Many elements give off characteristic light which can be used to help identify them.
strontium
sodium
lithium
potassium
copper
