After tracing many particles and examining the patterns, Rutherford deduced that the atom must have nearly all its mass, and positive charge, in a central nucleus about 10,000 times smaller than ...

For his work with radiation and the atomic nucleus, Rutherford received the 1908 Nobel Prize in chemistry. He was slightly put out, since he was a physicist and felt a bit superior to chemistry!

when he broke a nucleus into two or more smaller parts. German chemists Otto Hahn, a former student of Rutherford's, and Fritz Strassmann, repeated his experiments over the next four years and by ...

These experiments indicated that penetrating radiation was emitted that Rutherford hypothesised might be the nucleus of a hydrogen atom. Later painstaking research done by Patrick Blackett, at ...

A brilliant experimentalist and a natural leader, Rutherford transformed the Manchester department, building a team of brilliant associates who created nuclear physics. Highlights included 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 ...

mark), vital to the LEGEND research efforts. Ever since physicist Ernest Rutherford discovered the atomic nucleus in 1911, studying its structure and behavior has remained a challenging task. More ...

Most of the mass of an atom is found in the nucleus. 1913 Bohr In-depth work on Rutherford's model showed it had limitations. The electrons should just spiral in towards the positive nucleus.

He blasted beams of radioactive particles into nitrogen gas, which changed into oxygen while "spitting out" a hydrogen nucleus. University of Manchester Rutherford (right) juggled his experiments ...
