Atomic Models - Thomson and Rutherford

The video tutorial explores the evolution of atomic models, starting with the billiard ball model and J.J. Thomson's plum pudding model, which introduced the concept of electrons within a positively charged sphere. It then discusses Rutherford's gold foil experiment, which led to the discovery of the nucleus and the proposal of a new atomic model where electrons orbit a central nucleus. The video also covers the concepts of atomic number, mass number, isotopes, and isobars, highlighting the limitations of Rutherford's model in explaining atomic spectra.
