1. J.J. Thomson’s Atomic Model Presented by [Your Name]

2. Introduction J.J. Thomson proposed the 'Plum Pudding Model' in 1897 after discovering the electron. This model explained the structure of the atom as a positively charged sphere with embedded electrons.

3. Key Features of Thomson’s Atomic Model - Atom is a positively charged sphere. - Electrons are embedded within the sphere. - Resembles a 'Plum Pudding' or 'Watermelon' structure. - Atom is electrically neutral overall.

4. Diagram of Thomson’s Model

5. Limitations of Thomson’s Model - Could not explain atomic stability. - No nucleus in the model. - Disproved by Rutherford’s Gold Foil Experiment.

6. Conclusion Although Thomson’s model was later replaced, it was an important step in the development of atomic theory and helped in the discovery of electrons.
