jan 1, 470 BC - Democritus Model
Description:
The Democritus model is as simple as it looks; a solid, spherical particle is what he described as an atom. The idea that there were other components of an atom's structure wasn't considered as he viewed that it was an indivisible particle and that it couldn't be broken down any further. This model is the introduction of the atomic theory, and has progressed in complexity over a multitude of years.Added to timeline:
