but it failed to explain some phenomena and experiments. It was soon replaced by Rutherford’s nuclear model of the atom, which introduced the concept of the nucleus. The plum pudding model was not correct, but it was an important step in the development of atomic theory and modern physics....
Thomson's discoveries raised questions concerning the nature of the atom. He demonstrated that the atom is not the simplest unit of matter; rather, it has a structure. Thomson's atomic theory has informally been called the "plum-pudding" model, but the early history of this expression has ...
Though it would come to be discredited in just five years time, Thomson’s “Plum Pudding Model” would prove to be a crucial step in the development of theStandard Modelof particle physics. His work in determining that atom’s were divisible, as well as the existence of electromagnetic forc...

The plum pudding model of the atom by J. J. Thomson, who discovered the electron in 1897, was proposed in 1904 before the discovery of the atomic nucleus. In this model, the atom is composed of electrons (which Thomson still called "corpuscles", though G. J. Stoney had proposed that ...
physics. One specific discovery that Thomson is known for is called theplum pudding model. This discovery was an atomic model in which the interior of the atom was uniformly positively charged with negatively charged electrons spread throughout it. The plum pudding model was the standard model of...
