Atomic Theory Scientists and Their Contributions
Scientist (date)
Contribution(s)
Empedocles
(492 BCE and 432 BCE)
All matter is composed of four elements: fire, air, water, and earth. The ratio of these four elements determines the properties of the matter
Democritus
(460 BCE - 370 BCE)
Matter can be cut into its constituent parts, these parts still possess all the properties of the original matter. He named this “atomos”.
