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.
En este artículo discutiremos la teoría atómica de John Dalton, que fue el primer intento completo de describir toda la materia en términos de los átomos y sus propiedades.
John Dalton, English meteorologist and chemist, a pioneer in the development of modern atomic theory. His theory was notable for, among other things, positing that each element had its own kind of atom and that atoms of various elements vary in size and mass.

What is Atomic Theory? Dalton’s atomic theory was a scientific theory on the nature of matter put forward by the English physicist and chemist John Dalton in the year 1808. It stated that all matter was made up of small, indivisible particles known as ‘atoms’.
See how John Dalton built his atomic theory on principles laid out by Henry Cavendish and Joseph-Louis Proust. John Dalton and the development of the 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 ...
John Dalton Greenup (Eaglesfield, 6 de septiembre de 1766-Mánchester, 27 de julio de 1844) fue un naturalista, químico, matemático y meteorólogo británico. Entre sus trabajos destacan el modelo atómico y su tabla de pesos relativos de los elementos, que contribuyeron a sentar las bases de la química moderna.
The main points of Dalton's atomic theory, as it eventually developed, are: Elements are made of extremely small particles called atoms . Atoms of a given element are identical in size, mass and other properties; atoms of different elements differ in size, mass and other properties.
