What did Democritus atomic theory say?
What did Democritus atomic theory say?
Democritus believed that atoms were uniform, solid, hard, incompressible, and indestructible and that they moved in infinite numbers through empty space until stopped. Differences in atomic shape and size determined the various properties of matter.
What are Democritus 3 Main ideas about the atom?
All matter consists of atoms, which cannot be further subdivided into smaller particles. Atoms are extremely small—too small to see. Atoms are solid particles that are indestructible. Atoms are separated from one another by emptiness, or “void.”

Who said atoms are indivisible and indestructible?
Dalton hypothesized that the law of conservation of mass and the law of definite proportions could be explained using the idea of atoms. He proposed that all matter is made of tiny indivisible particles called atoms, which he imagined as “solid, massy, hard, impenetrable, movable particle(s)”.
Why was the Democritus model rejected?
2,500 years ago, Democritus suggested that all matter in the universe was made up of tiny, indivisible, solid objects he called “atomos.” However, other Greek philosophers disliked Democritus’ “atomos” theory because they felt it was illogical.
When was Democritus’s theory discovered?
About 400 B.C. the Greek philosopher Democritus suggested that all matter was formed of different types of tiny discrete particles and that the properties of these particles also determined the properties of matter.
How did Democritus reason for the existence of atoms?
Democritus thought that atoms are tiny, uncuttable, solid particles that are surrounded by empty space and constantly moving at random. Democritus surmised that different kinds of matter consist of different types or arrangements of atoms.
Who said atoms are invisible?
Dalton’s atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.

Why was Democritus’s original atomic theory revised?
