The first known writer to compare Thomson's model to a plum pudding was an anonymous reporter in an article for the British pharmaceutical magazine The Chemist and Druggist in August 1906. While the negative electricity is concentrated on the extremely small corpuscle, the positive electricity is distributed throughout a considerable volume.
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 ...
To explain the overall neutral charge of the atom, he proposed that the corpuscles were distributed in a uniform sea of positive charge. In this "plum pudding model", the electrons were seen as embedded in the positive charge like raisins in a plum pudding (although in Thomson's model they were not stationary, but orbiting rapidly). [32] [33]
Thomson further explained that ions are atoms that have a surplus or shortage of electrons. [53] Thomson's model is popularly known as the plum pudding model, based on the idea that the electrons are distributed throughout the sphere of positive charge with the same density as raisins in a plum pudding. Neither Thomson nor his colleagues ever ...

English: A simple diagram illustrating the Geiger-Marsden experiment. The left side shows the Thomson scattering pattern that the experimenters expected to see, given the plum pudding model of the atom. The right side shows the actual results, with Rutherford's new planetary model.
[3] [4] In it, Thomson developed a mathematical treatment of the motions of William Thomson and Peter Tait's atoms. [5] When Thomson later discovered the electron (for which he received a Nobel Prize), he abandoned his "nebular atom" hypothesis based on the vortex atomic theory, in favour of his plum pudding model.
