The atomic model timeline

In chemistry and physics, atomic theory is a scientific theory of the nature of matter, which states that matter is composed of discrete units called atoms it began. A timeline of the atom alchemists-500bc-1720--- develop the theory—that all metals are composed of mercury and sulfur and that it is possible to change base metals into gold democritus-442 bc---greek philosopher, who developed the atomic theory of the universe,his atomic theory anticipated the modern principles of the conservation of energy. Modern view (standard model) timeline: 1964 - present by the mid-1960's, physicists realized that their previous understanding, where all matter is composed of the fundamental protons, neutrons, and electron, was insufficient to explain the myriad new particles being discovered.
