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 ...

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 ...
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).

English: This is a diagram of an atom with seven electrons, as described J. J. Thomson in a lecture in 1905. In that lecture, he presented a diagram (File:Thomson_atom_electron_arrangements.jpg) in which he showed hypothetical arrangements of electrons in an atom. This image is based on Thomson's rendition of a seven-electron atom.
