Development of the atomic theory The idea that everything is made up of a few simpleparts originated during the 400s B.C. Atoms were once thought to be the smallest pieces of matter.However, it is now known that atoms are made up of protons, neutrons, and electrons.These subatomic particles are made up of quarks.The first idea of the atom came from the Greek philosopher Democritus. Democritus was the person who managed to develop the atomic theory that had been promulgated by Leucippus some time ago. An error occurred trying to load this video. just create an account. Because these atoms are constantly moving, they will eventually form some kind of a massive, spiraling cloud, according to Leucippus.

As a Pre-Socratic philosopher, Leucippus was among the first thinkers to look to science and reason instead of mythology in order to explain the universe. Leucippus (Pronounced: [lew sip' us]; 5th century BCE) was a Greek philosopher and scientist. Leucippus' theory of atomism was not necessarily in line with modern day chemistry and atomic theory, but Leucippus was one of the first to think of the world in such scientific terms. Though the atoms themselves never change, they do move around constantly in the void, and this movement causes them to arrange themselves into every object in the universe. 370 BCE) must go the credit for working out the detailed application of the theory and supporting it with a subtle epistemology. - Definition & Philosophy, Who was the Goddess Athena? ...

However, the term “atom” actually comes from the Greek adjective. Using scientific reasoning and observation, the Pre-Socratic philosopher Leucippus developed the theory of atomism, which posited that the whole universe is made up of solid atoms constantly moving through void, or empty space. It relied on Millikan's determination o, Working Scholars® Bringing Tuition-Free College to the Community. Leucippus argued that the void existed as empty space and he used this as a foundational assumption in his atomic theory. What separates the atoms is â¦ Look it up now! Leucippus likely lived in the 5th century BCE in the ancient Greek world. 5th cent. ic / ÉËtämik/ â¢ adj.
