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 ...

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 ...

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.

This defied the existing atomic model, which assumed atoms were uniformly spread out. From this, Rutherford proposed a ...

These particles should have passed straight through, according to the plum pudding model. However, many of them changed direction. Ernest Rutherford explained these results in his ‘planetary ...
