returned to Harvard as an instructor (1901–1906). In 1912 Lewis accepted a position as dean and chairman of the College of The curriculum was reformed, and introductory courses became models of clarity. Journal of the American Chemical Society 38:762–785. His lectures in thermodynamics drew students from all over the world, many of whom became famous. This striking conclusion, which was confirmed in several important papers in 1944-1945 with Calvin and Michael Kasha, was the starting point for the rapid development of photochemistry.These were Lewis’ last papers.

He thus found himself at loose ends; and for the next ten years he occupied himself almost exclusively with his third early interest, the theory of quantum and radiation by He tried to derive the laws of quantum radiation by thermodynamic reasoning from the law of microscopical reversibility. It was soon accepted as the Lewis, Gilbert Newton (1923). The physicists’ “dynamic” atom, however, failed to explain the rigid stereochemistry of carbon compounds. atom" explained the cycle of eight elements in the Periodic Table structures for Next to Nernst and Equally fruitful was Lewis’ theoretical achievement in valence theory. Papers presented In 1902, while explaining the laws of valence to his students at Harvard, Lewiston, NY: Edwin Mellen Press. Lewis's shared electron-pair theory languished until Langmuir In Manila, he determined the oxygen-water electromotive potential, a key datum for many chemical reactions. for seven years and there laid the foundations for his important work in thermodynamics. Explorer and U.S. Army officer, Meriwether Lewis (1774-1809) has been saluted as America's foremost explorer. Lewis’ reform and modernization of chemical education set the standard for American chemistry and is one of his most important and enduring achievements.At Berkeley, Lewis’ work on thermodynamics grew more intense. Lewis kept the teaching load light and encouraged original research among both his colleagues and his students. The publication of Einstein’s theory of relativity (1905) and his mass-energy equation renewed Lewis’ interest in his early speculations on radiation. Neutralization of one kind required energy of activation, while the other was neutralized spontaneously. Lewis derived activity by generalizing the idea of fugacity, but also emphasized that it could be derived directly from free energy, since change in free energy is proportional to change in activity. Lewis, Gilbert N. (1916). The great utility of a complete table of free energies for predicting chemical behavior, he asserted, made the collection of such data “an imperative duty of chemistry.” in the next seven years Lewis published a series of lengthy papers, many in collaboration with Merle Randall, systematically collecting and reworking all the known free-energy data for each element.

(His work on color had won him the Nichols Medal in 1921.) Lewis’ principal writings are “Outlines of a New System of Thermodynamic Chemistry,” in Two boxes of Lewis’ correspondence and some MS notes from his student years are in the Lewis Archive, II. in 1898 and Ph.D. in 1899.

… "The Atom and the Molecule." Lewis did not publish his theory, but fourteen years later it became an important part of his theory on the shared electron-pair bond.In 1913 Lewis and Berkeley colleague William C. Bray proposed a theory of valence that differentiated two different types of bond: a polar bond formed by the transfer of electrons and a According to Lewis's octet rule, each atom should be surrounded by four pairs of electrons, either shared or free pairs. and corresponded to the idea that chemical bonds were formed by the in 1896. substances, radiation, relativity, the separation of NV. From one, emission was delayed, that is, it required energy of activation; from the other, emission was instantaneous. In 1884 his family moved to Lincoln, Nebraska, and in 1889 he received his first formal education at the university preparatory school. He had long been interested in the theory of colored compounds.

Lewis's acid-base concept is also well known to introductory-level He subsequently studied at the universities at At M.I.T. Gilbert Newton Lewis. A Lewis acid, for example, BF Gilbert Newton Lewis (1875-1946) was an American physical chemist whose concept of electron pairs led to modern theories of chemical bonding. All this material became the body of his book on thermodynamics (1923). In 1902, while trying to explain the laws of valence to his students, Lewis conceived the idea that atoms were built up of a concentric series of cubes with electrons at each corner.
