John Dalton Research Paper
John Dalton
John Dalton (September 6, 1766 July 27, 1844) was an English chemist and physicist, born at Eaglesfield. He is most well known for his advocacy of the atomic theory and his research into color blindness.
Atomic theory
In 1800 he became a secretary of the Manchester Literary and Philosophical Society, and in the following year he presented the important paper or series of papers, entitled Experimental Essays on the constitution of mixed gases; on the pressure of steam and other vapors at different temperatures, both in a vacuum and in air; on evaporation; and on the thermal expansion of gases.
The second of these essays opens with the striking remark,
"There can scarcely be a doubt entertained respecting the reducibility …show more content…
These have made it in New System of Chemical Philosophy where John Dalton listed a number of elements, and common compounds.
Many of Dalton's ideas were acquired from other chemists at the time, such as Antoine Lavoisier and William Higgins. However, he was the first to put the ideas into a universal atomic theory, which was undoubtedly his greatest achievement. Five main points of Dalton's Atomic Theory
· Elements are made of tiny particles called atoms
· All atoms of a given element are identical
· The atoms of a given element are different from those of any other element
· Atoms of one element can combine with atoms of other elements to form compounds. A given compound always has the same relative numbers of types of atoms.
· Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process. A chemical reaction simply changes the way atoms are grouped together.
Unfortunately, Dalton had an additional statement that prevented his theory from being accepted for many years.When atoms combine in only one ratio, " It must be presumed to be a binary one, unless some cause appear to the …show more content…
The statement "Atoms cannot be subdivided, created, or destroyed into smaller particles when they are combined , separated, or rearranged in chemical reactions" is inconsistent with the existence of nuclear fusion and fission, although such processes are nuclear reactions, not chemical reactions. In addition, the statement "All atoms of a given element are identical in their physical and chemical properties" is not precisely true, as the different isotopes of an element have varying numbers of neutrons in their nuclei, though the number of protons remains consistent.

Various atoms and molecules as depicted in John Dalton's A New System of Chemical Philosophy (1808).
Dalton communicated his atomic theory to Thomson who, by consent, included an outline of it in the third edition of his System of Chemistry (1807), and Dalton gave a further account of it in the first part of the first volume of his New System of Chemical Philosophy (1808).
