WebThe plum pudding model was first proposed by the English Physicist Sir Joseph John J. Thomson soon after the discovery of the electron, but before the discovery of the atomic nucleus. The model tried to explain two properties of atoms then known: that electrons are negatively-charged particles and that atoms have no net electric charge. WebRutherford’s Experiment. In the early 1900’s, the plum pudding model was the accepted model of the atom. Proposed in 1904 by J. J. Thomson, the model suggested that the atom was a spherical ball of positive charge, with negatively charged electrons scattered evenly throughout.
