Thomson's plum pudding model

Thomson's plum pudding model suggests that atoms are made up of a positively charged substance with negatively charged electrons embedded within it, like raisins in a pudding or plums in a cake. This model was an early attempt to describe atomic structure, proposing that the positive charge was spread out evenly, balancing the negatively charged electrons. It helped explain some atomic behaviors before more precise experiments showed that atoms have a small, dense nucleus. Essentially, it visualizes the atom as a uniform, positively charged material with tiny, negatively charged particles scattered inside.
