Development of the Model of the Atom

The video explores the historical development of atomic theory, starting with Democritus' concept of indivisible atoms. It covers the discovery of the electron by JJ Thompson using cathode ray tubes, leading to the plum pudding model. Rutherford's gold foil experiment revealed the nucleus, altering the atomic model. Bohr further refined the model with defined electron orbits, and Chadwick discovered the neutron, completing the modern understanding of atomic structure.
