The History of Atomic Chemistry: Crash Course Chemistry

The video explores the evolution of atomic theory, starting with early ideas by Leucippus and Democritus, through the development of models by Lavoisier, Dalton, and Thompson. It highlights key experiments, such as Rutherford's gold foil experiment, leading to the discovery of the nucleus. Bohr's planetary model and Heisenberg's quantum theory are discussed, emphasizing the probabilistic nature of electron behavior. The video underscores the collaborative nature of scientific progress and the ongoing quest to refine our understanding of atomic structure.
