Chemical Atomic and Molecular Theory 1800-1900

Chemical, Atomic, and Molecular Theory 1800-1900 shows the chronological development of knowledge in the subject during the 19th century, from the atomic theory of Dalton in 1807 to the discovery of the electron in the 1890s. It is arranged in four colour-coded columns showing: new work resulting in the discoveries of the elements; the empirical tradition in chemistry; atomic theory; and the dialogue between the last two, which led to the concept of valency and the formation of the periodic table of the elements. Central to this chart is the Karlsruhe Conference of 1860, where chemistry was first recognized as one subject. In addition, key concepts are highlighted to mark their place in the history of chemistry. Like the other wallcharts in the series, this one can be used to answer fundamental questions about the discovery of the elements, the origins of chemical ideas and theories, and developments in the study of atomic and molecular theory.
