What are these negatively-charged particles?
I should do an experiment on the atom.
In 1912 and 1932
J.J. Thomson (born in Cheetham Hill and lived from 1856 - 1940) used a Crookes tube and discovered the existence of the electron. J.J. Thomson proposed the plum pudding model.
Ernest Rutherford (born in Brightwater and lived from 1871 - 1937) demonstrated that the atom has a tiny, heavy nucleus with his well-known gold foil experiment, which showed that the plum pudding model was incorrect.
In 1912, Niels Bohr (born in Copenhagen and lived from 1885 - 1962) worked with Rutherford to develop Rutherford's model further by suggesting that electrons move at high speed in a stable formation around the atomic nucleus. In 1932, James Chadwick (born in Bollington and lived from 1891 - 1974) discovered the neutron.
