Development of the Model of the Atom

The video discusses the historical development of the model of the atom, from the ancient Greek philosopher Democritus' idea of tiny, indivisible particles to modern-day understanding of electrons, protons, and neutrons. It explains the discovery and early understanding of electrons using cathode ray tubes, the plum pudding model, and Ernest Rutherford's experiment with alpha particles that led to the discovery of the nucleus. It also discusses the work of Niels Bohr and James Chadwick in the development of the modern atomic model, including the discovery of the neutron.
