In 1912 Bohr joined Rutherford. He realized that Rutherford's model wasn't quite right. By all rules of classical physics, it should be very unstable. For one thing, the orbiting electrons should ...

Bohr proposed adding to the model the new idea of quanta put forth by Max Planck in 1901. That way, electrons existed at set levels of energy, that is, at fixed distances from the nucleus.

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 ...

One of his chief interests was working out problems involved in the Bohr-Rutherford model of the atom. He just barely received his PhD in 1923 -- nearly failing because he had neglected his ...

Acceptance of this model grew after it was modified with quantum theory by Niels Bohr. For his work with radiation and the atomic nucleus, Rutherford received the 1908 Nobel Prize in chemistry.

Evidence from atomic line spectra supports the Bohr model of the atom using photon frequency calculations. Refraction of light The speed of light changes as it moves between media. This causes ...
