Plum Pudding Model

Model consists of a positively charged "pudding" containing negatively charged "plums" (electrons) randomly distributed throughout the atom.

The Plum Pudding model of the atom was an early atomic theory proposed in 1904 by JJ Thomson, also called Thomson's Model. It described the atom as being like a plum pudding, a viscous spheroid containing solid electrons inside it. It was disproven 5 years later by the Geiger-Marsden experiment.
