Atomos: Not to Be Cut

Atomos: Not to Be Cut. The History of Atomic Theory. Atomic Models. This model of the atom may look familiar to you. This is the Bohr model. In this model, the nucleus is orbited by electrons, which are in different energy levels.

History of the Atomic Model

History of the Atomic Model. Greeks (300 B.C). Hypothesized that matter cut into smaller and smaller pieces would eventually reach the atom (literally meaning indivisible) Thought there were 4 elements: Air, Fire, Earth, Water Findings based on reason, not empirical evidence
