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.
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.

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.
1 de dic. de 2014 · What Is John Dalton’s Atomic Model? Atomic theory – that is, the belief that all matter is composed of tiny, indivisible elements – has very deep roots. Initially, the theory appeared in...
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 ...
Dalton's Model of an Atom. Based on all his observations, Dalton proposed his model of an atom. It is often referred to as the billiard ball model. He defined an atom to be a ball-like structure, as the concepts of atomic nucleus and electrons were unknown at the time.
El modelo atómico de Dalton 1 fue el primer modelo atómico con base científica, propuesto en varios pasos entre 1803 y 1808 por John Dalton, 2 aunque el autor lo denominó más propiamente "teoría atómica".
