Physics and the Quantum Mechanical Model.

The Rutherfords model of the atom did not explain how an atom can emit light or the chemical properties of an atom. Bohrs model of the atom which was so successful in explaining the line spectra of single-electron atoms was a total failure in all attempts to describe multielectron atoms. Models of the Atom.

51 Light and Quantized Energy. Speed of light 2998 x 108 ms and is abbreviated c. The model doesnt explain how the electrons were arranged around the nucleus.

It also explains the significance of quantized energies of electrons as they relate to the quan tum mechanical model of the atom. DBohrs model focused on the electrons. The Bohr model propose that an electron is found only in specific circular paths or orbits around the nucleus.
