Democritus discovered the atom in 400 B.C.E. He believed it was the smallest particle to exist and could not be divided. He also believed that a void existed between two atoms. He wrote both the "Atomic Theory" and the "Void Hypothesis" Democritus proposed 7 points to his theory of atoms. These are: · All matter is composed of atoms, which are bits of matter too small to be seen. · These atoms CANNOT be further split into smaller portions. · There is a void, which is empty space between atoms. · Atoms are completely solid · Atoms are homogeneous, with no internal structure. · Atoms are different in: their sizes, their shapes, and their weights. · Atoms are the building blocks of life
Experimental Evidence
Democritus was a Greek Philosopher. He was not a scientist. He only hypothesized that the atom looked like a round ball. He did not conduct any experiments due to the fact he was a philosopher.
