Successes and failures of the Bohr model
- combining successfully Rutherford’s “solar system” model, with the Planck hypothesis on the quantified energy states at atomic level + Einstein’s photons
- explaining the atomic emission and absorption spectra
- explaining the general features of the periodic table
- a first “working” model for the atom
- a mixture of classical and quantum ideas (electrons move classically on orbits, but their possible energy states are quantified)
- postulates that on the allowed orbits electrons do not radiate
(conflict with Maxwell’s theory)
- could not account for the maximal electron numbers on one shell
- could not explain splitting of the spectral lines in magnetic fields
- it is a non-relativistic theory although the speed of the electrons is close to c
