Bohr’s Model of an Atom: Danish Physicist Niels Bohr received his Ph.D. from the University of Copenhagen in 1911. In 1922, he was awarded the Nobel Prize in Physics for his work on the atom’s ...

In 1913, Niels Bohr revised Rutherford's model by suggesting that the electrons orbited the nucleus in different energy levels or at specific distances from the nucleus. By doing this, he was able ...

If an electron is in an excited state it can return to a lower energy level. When it does this, it loses energy. The amount of energy it loses will be equal to the difference in the energy levels ...

1913 Bohr In-depth work on Rutherford's model showed it had limitations. The electrons should just spiral in towards the positive nucleus. Electrons move in fixed orbits, called electron shells ...

Beta decay involves the release of an electron. Both result in a mass defect ... Evidence from atomic line spectra supports the Bohr model of the atom using photon frequency calculations.
