Dalton's atomic theory

The video discusses the evolution of atomic theory, starting with Democritus' idea of indivisible particles. It then covers Dalton's atomic theory, which includes the concepts of indivisible atoms, identical properties of atoms of the same element, and the formation of compounds through fixed ratios of different atoms. Finally, it explains that chemical reactions involve the reorganization of atoms, which are neither created nor destroyed.
