Draft:Dalton's atomic model
From Wikipedia, the free encyclopedia
Dalton's atomic model[1] was the first scientifically based atomic model and it was proposed in many steps between 1803 and 1808 by John Dalton,[2] although the author categorized it as an "atomic theory". The model allowed to clarify for the first time why chemical compounds reacted in static stoichiometric proportions (Law of definite proportions), and why when two substances react to form two or more different compounds, then the proportions of these relations are integer numbres (Law of multiple proportions).[3] The model also clarified that even with the existance of a great variety of different substances, these could be explained in terms of a rather small quantity of elemental or elements constituents.
