Energy Levels of Atoms, Atomic Structure Description of emission and absorption line spectra of atoms. Failure of classical physics to explain the cause of these spectra Qualitative discussion of Bohr-Rutherford atom Description of the production of line spectra by both electron and photon bombardment recognition of energy levels of electrons within atoms transition of electrons between energy levels is associated with photon absorption or production quantitative evaluation of photon energies, frequencies and wavelengths as a result of transitions excitation of atoms by electron bombardment either through heat, electrically or other means excitation of atoms by photons, ionisation of atoms by high energy photons characteristic X-Ray spectra are due to electron energy changes typically to n=1 (K Lines) or n=2 (L Lines) for heavy elements Qualitative description of electron standing wave patterns applied to the Bohr-Rutherford atom.
