John Dalton and Atomic Theory Outline and Sources

privy Dalton and Atomic surmisal John Dalton was a British scientist who make important contributions to science and to the jotic hunt down specifically. I. Experiences in his life that led to his gratify in science and the study of the ingredient A. Education and teaching career brought him in contact with amateur meteorologists B. Mentors and meteorology tell his interest toward air pressure and properties of vaporific chemical elements C. Study of elements led to interest in comp unmatchablents of elements and his atomic theory. D.This is the general path to his discoveries. However, no one knows specifically how he reached nearly of his conclusions about atoms. II. Work on the atom and its contribution to the modern atomic example A. Lavoisiers impartiality influenced Daltons boldness that atoms can non be created, destroyed, or subdivided. B. Prousts Law of Definite Proportions led Dalton to his Law of ninefold Proportions C. He was trying to explain why water abso rbs incompatible gases in unalike proportions. D. Contributions 1. All matter consists of tiny particles, atoms. 2.Atoms cannot be created, destroyed, separated into small parts or transformed into some other element. 3. All atoms of the uniform element have identical weights, small-arm atoms of different elements have different weights. 4. When elements react, their atoms go in simple, whole-number ratios. 5. When elements react, their atoms sometimes combine in more than one simple, whole-number ratio. 6. When atoms combine in only one ratio, they are trust in a 11 ratio. III. Contributions which were eventually disproven and thus are not part of the modern model A.The composition that atoms that combine in only one ratio do so in a 11 ratio not only led him to misemploy conclusions, but also caused his theory to be rejected for many years. B. Another inconclusive idea was that atoms cannot be separated into smaller parts or transformed into another element. C. The ass ertion that all atoms of the same element have identical weights, while atoms of different elements have different weights is inaccurate. IV. Conclusion A. His work was important and foundational to modern atomic model. Sources 1 John Dalton (British Scientist) Atomic Theory. Encyclopedia Britannica Online. Encyclopedia Britannica, n. d.
