  1. What were Aristotle's contributions to the atomic theory? Flexi Says: Aristotle disagreed with Democritus and offered his own idea of the composition of matter. According to Aristotle, everything was composed of four elements: earth, air, fire, and water. The theory of Democritus explained things better, but Aristotle was more influential, so ...

    Philosophical atomism

    The idea that matter is made up of discrete units is a very old idea, appearing in many ancient cultures such as Greece and India. The word "atom" (Greek: ἄτομος; atomos), meaning "uncuttable", was coined by the Pre-Socratic Greek philosophers Leucippus and his pupil Democritus (c.460–c.370 BC). Democritus taught that atoms were infinite in number, uncreated, and eternal, and that the qualities of an object result from the kind of atoms that compose it. Democritus's atomism was refined and el...

    Near the end of the 18th century, two laws about chemical reactions emerged without referring to the notion of an atomic theory. The first was the law of conservation of mass, closely associated with the work of Antoine Lavoisier, which states that the total mass in a chemical reaction remains constant (that is, the reactants have the same mass as the products). The second was the law of definite proportions. First established by the French chemist Joseph Proustin 1797 this law states that if...

    Avogadro

    The flaw in Dalton's theory was corrected in principle in 1811 by Amedeo Avogadro. Avogadro had proposed that equal volumes of any two gases, at equal temperature and pressure, contain equal numbers of molecules (in other words, the mass of a gas's particles does not affect the volume that it occupies). Avogadro's lawallowed him to deduce the diatomic nature of numerous gases by studying the volumes at which they reacted. For instance: since two liters of hydrogen will react with just one lit...

    He did not believe in atomic theory, unlike Democritus, and thought that all elements on Earth were not made of atoms except for Earth, Fire, Water and Air, themselves. Aristotle believed that all substances were made of small amounts of these four elements of matter.

  4. Although Aristotle’s atomic theory has been disproven, his observations about the universe helped to send future scientists on a journey that would lead them closer to the truth. His ideas about the composition of matter were widely accepted for centuries and influenced many scientific discoveries.

  5. Mar 14, 2011 · Chemistry is the study of the structure and transformation of matter. When Aristotle wrote the first systematic treatises on chemistry in the 4 th century BCE, his conceptual grasp of the nature of matter was tailored to accommodate a relatively simple range of observable phenomena.

  6. Summary. 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.

  7. Sep 20, 2022 · According to Aristotle, everything was composed of four elements: earth, air, fire, and water. Deomcritus' theory better explained things, but Aristotle was more influential, so his ideas prevailed. It took almost two thousand years before scientists came around to seeing the atom as Democritus did.
