Who developed the first atomic model based on experimentation? aristotle and plato democritus chadwick john dalton?

John Dalton  - The idea of an atom- the smallest component of matter that could not be divided further - was proposed around the year 400 BC. However, Aristotle did not like the idea. He claimed that all matter was composed of various proportions of elements like air, water, earth and fire. However, he had no experimental evidence to prove it. It was only when John Dalton (an English chemist, physicist and meteorologist), after experimenting with various gases, discovered that all matter is, in fact composed of extremely small particles called atoms, that the atomic model was first accepted worldwide.
