to chemical systems. Gilbert Newton Lewis, forMemRS 1 (October 25 (or 23) 2, 1875 March 23, 1946) 3 4 was an American physical chemist known for the discovery of the covalent bond and his concept of electron pairs ; his, lewis dot structures and other contributions to valence.

Lewis Hall at Berkeley, built in 1948, is named in his honor. He insisted on the need for a new variable, the number of photons. Thermodynamics edit Most of Lewis lasting interests originated during his Harvard years.

He later revealed that he had been discouraged from pursuing this idea by his older, more conservative colleagues, who were unaware that Wilhelm Wien and others were successfully pursuing the same line of thought. 22 This was the first evidence for tetratomic oxygen. An hour later, he was found dead. His decision to resign may have been sparked by resentment over the award of the 1934 Nobel Prize for chemistry to his student, Harold Urey, for the discovery of deuterium, a prize Lewis almost certainly felt he should have shared for his work on purification. He included what became known as Lewis dot structures as well as the cubical atom model. A b Coffey (2008 310-15. Again Lewis theory did not interest his Harvard mentors, who, like most American chemists of that time, had no taste for such speculation. 16 Acids and bases edit Main article: Lewis acids and bases In 1923, he formulated the electron-pair theory of acidbase reactions. He became an assistant professor in 1907, associate professor in 1908, and full professor in 1911. Most chemists relied on the familiar thermodynamics of heat (enthalpy) of Berthelot, Ostwald, and Vant Hoff, and the calorimetric school. Lewis introduced the thermodynamic concept of activity and coined the term " fugacity ".
