Daltons Atomic Theory

John Dalton developed the first useful atomic theory of matter around 1803. In the course of his studies on meteorology, Dalton concluded that evaporated water exists in air as an independent gas. Solid bodies can't occupy the same space at the same time, but water and air could. If the water and air were made of discrete particles, evaporation might be viewed as a mixing of water particles with air particles. He performed a series of experiments on mixtures of gases to determine what effect properties of the individual gases had on the properties of the mixture as a whole. While trying to explain the results of those experiments, Dalton developed the hypothesis that the sizes of the ...

Some of the details of Dalton's original atomic theory are now known to be incorrect. But the core concepts of the theory (that chemical reactions can be explained by the union and separation of atoms, and that these atoms have characteristic properties) are foundations of modern physical science.
Most of Dalton’s ideas have changed in the scientific world by: 1. Many of his conclusions were concluded to be incorrect or false. 2. They were used them to explain some of the happenings of the universe and the world surrounding us (humans, animals etc.). 3.
