What was Thomson's model of the atom often referred to as?

Thomson's model of the atom is often referred to as the "plum pudding model." In this model, Thomson proposed that atoms consist of a sphere of positive charge with negatively charged electrons embedded within it, resembling a pudding with plums dispersed throughout. This was a significant development in understanding atomic structure, as it suggested that the atom was not indivisible but composed of smaller particles. The model illustrated the idea that electrons are scattered within a positively charged 'soup,' which helped to introduce the concept of subatomic particles. Although later models, such as Rutherford's, revealed more about the atom's structure, the plum pudding model was foundational in the evolution of atomic theory.
