Early beginnings
- 600 BCE[1] Kanada theorizes the existence of four kinds of atoms, which could combine to produce diatomic and triatomic molecules.
- 430 BCE[1] Democritus speculates about fundamental indivisible particles—calls them "atoms"
- 200 BCE[1] Jainism calls atom Paramanu which can neither be created nor destroyed. It is eternal, i.e., it existed in the past, exists in the present and will continue to exist in the future. It is the permanent basis of the physical existence. The entire physical existence is composed of these ultimate atoms.
