Who discovered the atom?

In: History of Science [Recategorize]

In the 5th cent. B.C. the Greek philosophers Democritus and Leucippus proposed that matter was made up of tiny, indivisible particles they called atom, or in Greek "a-tomos". The reason why they assumed this is because nothing can come from nothing. Around 1803, John Dalton (1766-1844) developed the first useful atomic theory of matter. He imagined the atom as a sphere full of an electrically positive substance mixed with negative electron. Then in 1897, Thompson discovered the first component part of the atom: the electron, a particle with a negative electric charge.

Discovery of the Atom

By the 19th century, technology had advanced greatly and many elements had been discovered to work with. Using the available elements scientist such as John Dalton and Amedeo Avogadro forced them to interact with one another. From these interactions they were able to prove the existence of the atom.
