John Dalton FRS (/ ˈ d ɔː l t ən /; 5 or 6 September 1766 – 27 July 1844) was an English chemist, physicist and meteorologist. [1] He introduced the atomic theory into chemistry. He also researched colour blindness ; as a result, the umbrella term for red-green congenital colour blindness disorders is Daltonism in several languages.
Dalton's 1806 list of known elements by atomic weight. In 1808–10, British natural philosopher John Dalton published a method by which to arrive at provisional atomic weights for the elements known in his day, from stoichiometric measurements and reasonable inferences. Dalton's atomic theory was adopted by many chemists during the 1810s and ...
Heaven Lake is the debut novel of American author John Dalton published in 2004. It won both the 2005 Sue Kaufman Prize from the American Academy of Arts and Letters [1] and the 2004 Barnes & Noble Discover Great New Writers Award in Fiction. [2]
Dalton thought that water was a "binary compound", i.e. one hydrogen atom and one oxygen atom. Dalton did not know that in their natural gaseous state, the ultimate particles of oxygen, nitrogen, and hydrogen exist in pairs (O 2, N 2, and H 2). Nor was he aware of valencies. These properties of atoms were discovered later in the 19th century.
But in other cases, he got their formulas right. The following examples come from Dalton's own books A New System of Chemical Philosophy (in two volumes, 1808 and 1817): Example 1 — tin oxides: Dalton identified two types of tin oxide. One is a grey powder that Dalton referred to as "the protoxide of tin", which is 88.1% tin and 11.9% oxygen ...

John Dalton's list of molecular weights is first published. [2] Joseph Louis Gay-Lussac discovers that water is composed of two parts hydrogen and one part oxygen by volume. [3] [4] Jane Marcet's elementary textbook for young people, Conversations on Chemistry ("intended more especially for the female sex"), is published anonymously in London ...
