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 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 ...

Tell us about your education. My formal schooling began when I was seven, at the Gammelholm School in Copenhagen, Denmark. I did well in all my studies -- well, all studies except composition ...

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 ...

Niels Bohr adapted Ernest Rutherford's nuclear model. Bohr did calculations that led him to suggest that electrons orbit the nucleus in shells. The shells are at certain distances from the nucleus.

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 ...

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." ...
