â Surprisingly, some of these Greek ideas led to similar modern ideas. Democritus (462-370 B.C.): proposed that all matter was made up of tiny, indivisible. particles called atomos (meaning âindivisibleâ) or atoms. Empedocles (490-430 B.C.): suggested all matter was composed of four basic elements: air, water, fire, and earth.
In 1911, although he could not prove that it was positive or negative, he theorized that atoms have their charge concentrated in a very small nucleus, and thereby pioneered the Rutherford model of the atom, through his discovery and interpretation of Rutherford scattering in his gold foil experiment.
