Bohr's Model

Bohr (1920s)

  • Bohr based his model on the energy (light) emitted by different atoms
  • Each atom has a specific spectra of light
  • Light travels as photons
  • The energy photons carry depends on their wave length
Bohr Model

To explain this emission spectra Bohr suggested that electrons occupy shells or orbitals.

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 orbital they release energy as a photon of light

  1. Very cool video!

    A few more examples of how to draw Bohr diagrams are need though.
