Thomson's model marks the moment when the development of atomic theory passed from chemists to physicists. While atomic theory was widely accepted by chemists by the end of the 19th century, physicists remained skeptical because the atomic model lacked any properties which concerned their field, such as electric charge, magnetic moment, volume, or absolute mass.
The Thomson problem is a natural consequence of J. J. Thomson's plum pudding model in the absence of its uniform positive background charge. [ 12 ] "No fact discovered about the atom can be trivial, nor fail to accelerate the progress of physical science, for the greater part of natural philosophy is the outcome of the structure and mechanism ...
James Arnold Crowther (1883–1950) was a British physicist who worked on beta particle scattering with JJ Thomson in connection with the first tests of modern atomic physics (see plum pudding model) as well as X-ray scattering including practical applications in medical radiology.

The cathode ray tube by which J. J. Thomson demonstrated that cathode rays could be deflected by a magnetic field. The Thomson Medal and Prize is an award which has been made, originally only biennially in even-numbered years, since 2008 by the British Institute of Physics for "distinguished research in atomic (including quantum optics) or molecular physics".
