This "Rutherford model" would form the basis of modern atomic physics and paved the way for the quantum theory later developed by Niels Bohr. THE DISCOVERY OF THE PROTON In 1917, Rutherford made ...

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 made a series of discoveries about the nature of atoms and, working with colleagues Hans Geiger and Ernest Marsden, presented a planetary model of the atom in 1911. In it, he laid out ...

The Bohr model is a neat but quite imperfect depiction of the inner workings of an atom before things got too muddled up by quantum principles.
