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 ...

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 ...

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 ...

Highlights included the discovery of the atomic nucleus in 1911, Henry Moseley's physical explanation of the different properties of chemical elements and the consequent Rutherford-Bohr model of the ...

Scientists changed the model so that it could explain the new evidence. 1909-1911 Rutherford (and Geiger and Marsden) Some positively charged particles fired at gold foil bounced back when they ...
