The idea of the atom was first developed by Greek philosophers Leucippus and Democritus in 5th century BC. Their idea was overlooked until Antoine Lavoisier's experiments were done in the 18th century.
John Dalton put forward the idea that each element is made of a different sort of atom. Each kind of atom had its own properties such as an individual mass.
