WebTherefore, this model is also referred to as the watermelon model, the plum pudding model or the raisin pudding model. An important aspect of this model is that it assumes that the mass of the atom is uniformly distributed over the atom. Thomson’s atomic model was successful in explaining the overall neutrality of the atom. WebThe ‘Plum Pudding Model’ is one of the many theories that were hypothesized to explain atomic structure, in the beginning of the 20 th century. J.J.

The Rutherford model supplanted the “plum-pudding” atomic model of English physicist Sir J.J. Thomson, in which the electrons were embedded in a positively charged atom like plums in a pudding.
The plum pudding model is one of several historical scientific models of the atom. First proposed by J. J. Thomson in 1904 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 … See more It had been known for many years that atoms contain negatively charged subatomic particles.
