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 ...

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 ...

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.

Rutherford deduced the nature of the atom. (NZ Herald Archive) Three years after winning the Nobel Prize for his work on radioactivity, Ernest Rutherford made the second of his major discoveries.
