Democritus was the first scientist to create a model. He was the first to discover that all matter is made up of invisible particles called atoms. His model of the atom was just a round solid ball. He knew nothing about electrons protons or neutrons.

DEMOCRITUS ATOMIC MODEL
Aristotle disagreed with Democritus's model of the atom. He felt that there was no smallest part of matter and the differences between substances were made of Earth, fire, air, and water. Aristotle in a way did not have a model because he believed atoms did not exist.
