Bohr entered the story in 1912 when, working in the laboratory of Ernest Rutherford in Manchester, he devised a quantum theory of the atom. In Bohr’s picture, the electrons encircling the atomic ...

When an electron dropped from a high-energy orbit to a lower-energy one, it gave out light with an energy equal to the ...

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 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 ...

Rutherford's work with Niels Bohr in the 1920s, predicting the existence of neutrons, was later confirmed in an experiment by Rutherford's colleagues. "John Cockcroft and Ernest Walton developed a ...

As a post-doctoral student, Bohr first conducted experiments under J. J. Thomson at Trinity College, Cambridge. In 1912 he joined Ernest Rutherford at Manchester University and he adapted ...

Henry Moseley's physical explanation of the different properties of chemical elements and the consequent Rutherford-Bohr model of the atom were developed there in 1915, and the 'splitting of the atom' ...
