• Bohr’s model explains the spectral lines of the hydrogen atomic emission spectrum.
  • While the electron of the atom remains in the ground state, its energy is unchanged.
  • When the atom absorbs one or more quanta of energy, the electron moves from the groundState orbit to an excited state orbit that is further away.
  • The energy that is gained by the atom is equal to the difference in energy between the two energy levels.
  • The change in energy, , then translates to light of a particular frequency being emitted.
