Democritus, an ancient Greek philosopher, first proposed the idea of atoms as indivisible particles. Dalton's atomic theory, developed in the 19th century, expanded on this concept by introducing the idea of atoms combining in specific ratios to form compounds. Dalton's theory built upon and refined Democritus' original idea of atoms, laying the foundation for modern atomic theory.
equal to the atomic mass of the element expressed in daltons. It is essentially the mass of one mole of the element in grams.
One molecule of water has a total molecular weight of approximately 18 daltons. This weight is calculated by adding the atomic weights of two hydrogen atoms (each 1 dalton) and one oxygen atom (approximately 16 daltons).
Democritus was an ancient Greek philosopher who was a pupil of Leucippus. Democritus suggested that different types of small discrete particles formed all matter. He suggested that the properties of the tiny particles are what determined the property of the matter.
The atomic theory of matter can be attributed to the ideas proposed by the ancient Greek philosopher Democritus. He hypothesized that all matter is composed of indivisible and indestructible particles called atoms, which differ in shape, size, and arrangement. Democritus' atomic theory laid the foundation for modern atomic theory.
Democritus began the atomic theory. He was the first to theorize that if you keep cutting stuff down smaller and smaller, you will eventually reach the smallest piece possible. He was, however, put down by Aristotle. Aristotle had a larger and stronger following, so people dismissed Democritus as a lunatic.
Democritus lived between approx. 460 bc and approx. 370 bc.
democritus was greek philosophers.
Democritus achievements are his atomic theory and his book -on the little order of the world- which describes his atomic theory.
They both thought the same theory but Dalton had evidence to prove it, unlike Democritus.
the atomic theory of the universe
The term used by Democritus to identify the particles of an element is atomic theory. It was thought up by John Dalton between the years 1766 and 1844.

The ancient Greeks did not perform any experiments to test the atomic theory proposed by Democritus. To the ancient Greeks the atomic theory was a part of philosophy, not science.
