-Rutherford's model was inherently unstable
-Protons and electrons should attract each other
-Matter emits light when it is heated (blackbody radiation)
-Light travels as photons
-The energy photons carry depends on their wavelength
-Bohr based his model on the energy (light) emitted by different atoms
-Each atom has a specific spectra of light
-To explain this emission spectra Bohr suggested that electrons occupy shells or orbitans
Bohr's Theory
-Electron's 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 of light
Here's a picture of a couple of Bohr models: http://lapse.nerdvana.org.au/comedy/pics/atom-bohr.gif
