The plum pudding model, proposed by J.J. Thomson in 1904, describes the atomic structure as a sphere of positive charge with negatively charged electrons embedded within it, resembling a plum pudding dessert. The "plums" represent the electrons, while the "pudding" symbolizes the diffuse positive charge that balances the overall neutral charge of the atom. This model was later superseded by the Rutherford model after the discovery of the atomic nucleus, which revealed a more complex structure of the atom.
