Thomson

Thomson's atomic model, proposed by J.J. Thomson in 1897, suggests that atoms are like "plum pudding" desserts, with a positive charge spread throughout and negatively charged electrons embedded within. This model was an early attempt to explain atomic structure, indicating that atoms are not tiny indivisible particles but contain smaller charged components. It helped scientists understand that atoms have internal parts with electrical charges, paving the way for more advanced models of atomic structure in physics and chemistry.
