In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the center of the atom. The electrons are distributed around the nucleus and occupy most of the volume of the atom. It is worth emphasizing just how …

In …7 Contributions by Joseph Thomson to Chemistry and Science. Some Contributions by Joseph Thomson Are the discovery of the electron, its atomic model, the discovery of isotopes or the cathode ray experiment. Joseph John Thomson was born in Cheetam Hill, a district of Manchester, England, on December 18, 1856.Most relevant to the field of chemistry, Thomson found that the mass-to-charge ratio of cathode rays is independent of the nature of the metal electrodes or the gas, which suggested that electrons were fundamental components of all atoms. ...
