How did the early ideas about atoms Democritus and Aristotle discussed differ from the work of scientists that came later?

Democritus proposed that matter is made up of indivisible particles called atoms, which differ in shape and size. Aristotle, on the other hand, believed in four elements (earth, water, air, fire) and did not support the idea of indivisible particles. Later scientists built on Democritus's concept by discovering the structure of the atom, including subatomic particles and the existence of a nucleus.
