Democritus theorized that all matter was made up of indivisible, microscopic substances which were held together in various combinations that formed the objects that were perceived by our eyes. Because the word in Greek for indivisible is 'atomos', this theory gave rise to the atom. Democritus proposed this theory about 420 B.C.

Who believed that an atom is made up of an indivisible particle?
John Dalton: In the late 1700s, John Dalton developed the atomic theory on which all current understandings are based.
Who was the first person to state that matter is made up of atoms?
The idea that matter is made up of atoms was proposed by the ancient Greek philosopher Democritus around 400 BCE. He believed that all matter consists of tiny, indivisible particles called atoms.
Who was the English scientist that said all matter is made up of a relatively small number indivisible particles called atom?
The English scientist who proposed that all matter is made up of indivisible particles called atoms was John Dalton. He introduced his atomic theory in the early 19th century, which laid the foundation for modern chemistry.
Who was the first scientist to give evidence to support democritus idea about atoms?
Democritus did not do any experiments or provide solid evidence for his theory on the atom. In the 5th century B.C, Democritus proposed an atomic model in which all matter is made up of small indestructible units called atoms.
What are john Dalton Discoveries?
John Dalton is best known for his pioneering work in the development of modern atomic theory. His discoveries included the concept that all matter is made up of indivisible particles called atoms, that each element is made of unique atoms, and that chemical reactions involve rearrangement of these atoms. Dalton's work laid the foundation for future advancements in the field of chemistry.
Who made contribution to chemistry?
john Dalton
Both Democritus and Dalton suggested that matter is made up of atoms?
true
Who made the contributations to the theory?
Leukippus, Democritus, Dalton, Bohr, Rutherford, Thomson and many others.
What ideas about the atom did Democritus and John Dalton share?
Democritus and John Dalton both believed that atoms were indivisible and made up all matter. They shared the idea that atoms were small, solid particles that could not be divided further.
What is Democritus' contribution to wikianswerscomQWhat is Democritus' contribution to society?
Democritus, an ancient Greek philosopher, is known for proposing the concept of atomism - the idea that all matter is made up of tiny, indivisible particles called atoms. His ideas laid the foundation for modern atomic theory and influenced the development of scientific thought in fields such as chemistry and physics.
Who made contributions to the atomic theory?
Leukippus, Democritus, Dalton, Bohr, Rutherford, Thomson and many others.
Who proposed the idea that everything is made of atoms?
It was John Dalton in the early 1800s.
Who made the Latin name for atom?
Some say that Democritus named the atom "ATOMUS" which means "invisible" others say John Dalton but i would go with the former (Democritus).
What is the difference between Dalton's atomic theory and Democritus' atomic theory?
When an ancient Greek asked if an object could be subdivided indefinitely, some said yes and some said no. Neither side had any physical evidence for their point of view, nor did they seek any. The only contribution to modern science, apart from the question itself, was the word atomos (indivisible) that Democritus used in the debate. John Dalton made a contribution of a quite different order. He said that matter did consist of atoms; he said that all atoms of the same element were identical atoms with the same mass. He cited physical (that includes chemical) evidence to support his assertions. Dalton said more about atoms, but all based on evidence, rather than opinion. Democritus's theory was philosophy. Dalton's was science as we understand it today.
What did democritus create?
well, according to my knowledge, he didn't really "create" anything in fact he found out that everything is made of atoms but he described atoms as being solid spheres. But many people disagree with his theory. Modern Chemistry would have not been the same without the contribution of our future scientist Democritus the man who developed atomism.
Who described atoms that they are small hard particles?
John Dalton. N.B.: John Dalton [born: September 6, 1776; died: July 27, 1844, at age 67] was an English chemist and physicist who claimed matter was made up of tiny particles and that these particles were identical for any given kind of matter. Moreover, he claimed these particles were indivisible and could neither be created nor destroyed in any chemical process, only be altered in the manner they were grouped.
Who believed that an atom is made up of an indivisible particle?
John Dalton: In the late 1700s, John Dalton developed the atomic theory on which all current understandings are based.
