In time, this would lead him to conclude things about how atoms interacted, the weight of atoms, and to design laws that establish atomic theory as scientific discipline dalton’s gas laws: dalton came up with his theory of atoms as a result of his research into gases.
John dalton, (born september 5 or 6, 1766, eaglesfield, cumberland, england—died july 27, 1844, manchester), english meteorologist and chemist, a pioneer in the development of modern atomic theory early life and education dalton was born into a quaker family of tradesmen his grandfather jonathan dalton was a shoemaker, and his father, joseph, was a weaver. 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. Dalton's atomic theory democritus first suggested the existence of the atom but it took almost two millennia before the atom was placed on a solid foothold as a fundamental chemical object by john dalton (1766-1844.

John dalton came up with his atomic theory after observing manychemical reactions in his lab it made him think that there wereinvisible atoms in materials. The experiment that led dalton to his atomic theory was firing alpha particles at gold foil he observed that most of the alpha particles passed straight through the foil, but a few (about 1 in 8000) were scattered at large angles, some even coming back the way they came.
John dalton came up with his atomic theory after observing many chemical reactions in his lab it made him think that there were invisible atoms in materials.
John dalton - atomic theory: by far dalton’s most influential work in chemistry was his atomic theory attempts to trace precisely how dalton developed this theory have proved futile even dalton’s own recollections on the subject are incomplete he based his theory of partial pressures on the idea that only like atoms in a mixture of gases repel one another, whereas unlike atoms appear to. By 1808, an english chemist by the name of john dalton finally came up with the atomic theory of matter he believed that all atoms of a single substance were identical and that atoms of different substances differed by weight.
Seeking to expand on his theory, he readdressed the subject of atomic weight in his book a new system of chemical philosophy, published 1808 in a new system of chemical philosophy , dalton introduced his belief that atoms of different elements could be universally distinguished based on their varying atomic weights. Dalton's atomic theory it was in the early 1800s that john dalton , an observer of weather and discoverer of color blindness among other things, came up with his atomic theory let's set the stage for dalton's work.
Chemist john dalton is credited with pioneering modern atomic theory he was also the first to study color blindness the majority of conclusions that made up dalton's atomic theory still. Finally, dalton published a full account in his own textbook, a new system of chemical philosophy, 1808 and 1810 dalton estimated the atomic weights according to the mass ratios in which they combined, with the hydrogen atom taken as unity. This article will discuss john dalton's atomic theory, which was the first complete attempt to describe all matter in terms of atoms and their properties basis for dalton's theory dalton based his theory on two laws: the law of conservation of mass and the law of constant composition.
