Democritus (Greek Model) Democritus' model claimed that matter consists of invisible particles called atoms and emptiness (empty space). He claimed that atoms are indestructible and unchangeable. In addition, they are homogeneous, that is, they do not have an internal structure. His atomic model was solid and stated that all atoms differ in size, shape, mass, position and location, and there is a void between them. (jan 3, 50 BC – jan 1, 1808)
