Electron
Explanation
The plum pudding model was one of several scientific models that were proposed for the structure of the atom, an essential building block of matter. Proposed by J. J. Thomson in 1904, this model came shortly after the discovery of electron. According to this model, an atom resembles a delicious plum pudding: positively charged material would represent the dough, while the 'plums' sitting in it would represent the electrons. Therefore, the subatomic particle whose discovery led to the plum pudding model is the electron.
