But his mark on science and history was worldwide ... collapsing the atom. Bohr proposed adding to the model the new idea of quanta put forth by Max Planck in 1901. That way, electrons existed ...

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 ...

Bohr made numerous contributions to physics during his career, but it was his work on atomic structure and quantum theory that won him the 1922 Nobel Prize for Physics. (Courtesy: Sam Falconer, Debut ...

Standard quantum theory as developed by the likes of Niels Bohr and Werner Heisenberg in ... Two quantum field theories lie at the heart of the standard model of particle physics.

Most of the mass of an atom is found in the nucleus. 1913 Bohr In-depth work on Rutherford's model showed it had limitations. The electrons should just spiral in towards the positive nucleus.

Acceptance of this model grew after it was modified with quantum theory by Niels Bohr. For his work with ... the discovery of atomic fission. "All science is either physics or stamp collecting." ...
