8 Questions
Explain the limitations of the Bohr model of the atom as mentioned in the text.
The limitations mentioned in the text include the model's application only to H-atom and some H-like atoms, neglect of nucleus motion, and consideration of only circular orbits while ignoring elliptical orbits.
What atoms does the Bohr model apply to?
The Bohr model applies to H-atom and some H-like atoms such as He+, Li++, Be+++. It does not apply to other atoms.
What aspect of the atom's motion is neglected in the Bohr model?
The Bohr model neglects the nucleus motion and assumes it is fixed, while in reality, it is moving (albeit in a slight movement) with the electron around the axis passing through their common center of mass. It also neglects the spin momentum of p+ and n.
What modification did Summerfield make to the Bohr model?
Summerfield extended the results to include elliptical orbits, which were previously ignored by the Bohr model. This extension was made by observing the H-atom spectral lines.
Who confirmed the neglect of spin momentum in the Bohr model?
The neglect of spin momentum in the Bohr model was confirmed later by Pauli.
