1. Bohr

   • Fixed Orbits (s p d)
   • You can know where the electron will be
   • Electrons dont loose energy while orbitting
   • An electron can change orbit by quantized amt of energy
     • doing so gives off energy in a spectrum
   • Doesn't explain spectrum on MULTI electron systems
   • Doesn't explain affect of magnetic field on spectum
   • Thought orbits were flat orbits

2. De Broglie

   • Small particles may at times display 'wave-like' properties
   • wavelength = h/mu or h/p or h/mv
   • wave particle duality

3. Planck

   • Plancks Constant: h = 6.626E-34
     • E = hv
       • As frequency increases, energy increases
   • Energy must increase in quatums

4. Heisenberg

   • deltaX deltaP >= h/4pi
   • The more accurate you know a location, the less accurate you'll know momentum

5. Schrodinger

   • Wave Function
     • probability of an electron being at a spot
       • nodes = 0 likely hood
       • electron probabilty density
