Which model is known for being represented as the 'Chocolate Chip Cookie' model?

The 'Chocolate Chip Cookie' model is associated with Thomson's Model of the atom. In this model, the atom is visualized as a sphere of positive charge (the cookie dough) with negatively charged electrons (the chocolate chips) embedded within it. This representation illustrates the concept of the atom being made up of smaller particles, with electrons distributed throughout a positively charged medium.

Thomson's Model was one of the first to suggest that atoms contain smaller subatomic particles and was developed following his discovery of the electron. This model helped advance the understanding of atomic structure, paving the way for subsequent models that refined our view of the atom. The analogy of chocolate chips in a cookie effectively captures the idea of electrons being spread out within the atom rather than being in fixed orbits or arrangements, which was a significant departure from earlier atomic theories.
