October 12 class (Bohr Notes)

Bohr (1920's)

-Rutherfords first tried to make a model before Bohr, his model was very unstable

-Bohr based his model on the energy (light) emitted by different elements
-Bohr believed each atom has a specific spectra of light 

Bohr's Theory

-electrons exist in orbitals
-when they absorb energy they move to a higher orbital
-as they fall from a higher orbital to a lower one they release energy as a photon light
