World of Chemistry on Gilbert Newton Lewis
Gilbert Newton Lewis is best known for his theory on the natures of acids and bases, as well as for his explanation of chemical bonding. However, he also made successful contributions to thermodynamics (a branch of physics concerned with the properties of heat), photochemistry, and isotope separation, which is the sorting of a mixture of isotopes--or a species of an element with the identical atomic number but different atomic mass--into its respective isotopic constituents. In addition, his "electron dot" structures have provided a visual model for how molecules hold together.
Lewis's ideas about chemical bonding are still among the first theories taught to beginning chemistry students. When Lewis began his career, theories of energy and energy flow (thermodynamics) were almost never applied to practical chemical problems. His efforts made considerable progress toward finding ways of integrating thermodynamic principles into real chemical systems. Lewis helped to revolutionize chemical education...
