The concept of the atom being likened to a "plum pudding" model was proposed by the British physicist J.J. Thomson. This model, introduced in the early 1900s, described the atom as a spherical cloud of positive charge with negatively charged electrons embedded within it, much like plums in a pudding.

This analogy was a significant development in the understanding of atomic structure at the time, as it provided a visual way to conceive of atoms and their internal composition. However, the plum pudding model was later challenged and ultimately replaced by more accurate models, particularly following Ernest Rutherford's gold foil experiment, which provided evidence for a nucleus at the center of the atom.
