NettetBohr's model of the atom is considered to be important by general chemistry textbooks. A major shortcoming of this model was that it could not explain the spectra of atoms containing more than one electron. In order to increase the explanatory power of the model, Sommerfeld hypothesized the existence of elliptical orbits. This study has the ... NettetPostulates of Bohr’s Atomic Model. The three Postulates stated by Neil Bohr are: The electron can revolve in certain stable orbits around the Nucleus without radiating any energy, in contrast to what classical electromagnetism suggests. The stable orbits are called stationary orbits. They are gained at certain distinct distances from the nucleus.

NettetMerit of Bohr model. Provides a picture of atomic structure that illustrates some properties of atoms. Example: Bohr orbit is used to explain several properties in relation to magnetism. Limitations of Bohr model. Cannot be used to predict structure and measure relative intensities of spectral lines. Does not apply to multi-electrons atoms. NettetThe quantum mechanical model of the atom comes from the solution to Schrodinger’s equation. Quantization of electron energies is a requirement in order to solve the equation.
