Aristotle believed in the continuous and infinitely divisible nature of matter. He was the first person to use the word “atom”/ Life Persona.Īristotle, a prominent philosopher of the time, rejected the atomic theory in favour of his own ideas, which dominated scientific thought for centuries.

Therefore, the major difference between Democritus and Dalton atomic theory is that the Democritus atomic theory is an ancient theory which scientists later refined and elaborated whereas the Dalton atomic theory is a comparatively modern, scientific theory that we cannot discard due its important statements. The two atomic theories, Democritus atomic theory and Dalton atomic theory, differ from each other according to their current usage. Summary – Democritus vs Dalton Atomic Theory The below infographic on the difference between Democritus and Dalton atomic theory describes all the possible differences between both the theories. However, they mainly differ according to the current usage of the theory therefore, the key difference between Democritus and Dalton atomic theory is that Democritus atomic theory is an ancient theory that scientists later refined and elaborated whereas Dalton atomic theory is a comparatively modern, scientific theory that we cannot discard due its important statements. Whereas, the Dalton atomic theory describes that atoms are invisible to the naked eye, we cannot either create or destroy them, all atoms of the same chemical elements are equal and compound forms from the combination of different chemical elements in simple ratios. A significant difference between Democritus and Dalton atomic theory is that according to the Democritus atomic theory, the atoms are infinite in number, uncreated, and eternal, and that the qualities of an object result from the kind of atoms that compose it. What is the Difference Between Democritus and Dalton Atomic Theory?ĭemocritus atomic theory is the ancient theory that describes the nature of matter in terms of atoms whereas Dalton atomic theory is a modern scientific theory that describes the nature of matter in terms of atoms. When forming a compound, different elements combine in different but simple numerical ratios.All atoms of the same chemical element are equal in mass and other properties.We cannot either create or destroy atoms.Each chemical element contains extremely small particles that are invisible to the naked eye atoms.Thereafter, he developed the Dalton atomic theory which has the following statements. It states that if the same two elements can be combined to form a number of different compounds, then the ratios of the masses of the two elements in their various compounds will be represented by small whole numbers. With the development of the law of conservation of mass and the law of definite proportions, John Dalton developed a new idea as the law of multiple proportions. What is Dalton Atomic Theory?ĭalton atomic theory is a modern scientific theory that describes the nature of matter in terms of atoms. However, this theory was refined and elaborated later by the Greek philosopher Epicurus (341 – 270 BC). We cannot create them, and the composition of atoms in a substance determines the qualities of that substance.
