Gilbert Lewis: Main areas of researchIn his work on valence theory, Lewis also established a cubic atom model and used it to explain the cycle of eight elements in the periodic table. At the Massachusetts Institute -

Lewis spent his time at Berkeley on the systematic collection of the known data of free energies and entropy values. In this he was also partly assisted by Randall. With Brey, Lewis developed a dualistic valence theory in 1913. With this, polar and non-polar bonds could be distinguished. His work on the theory of chemical bonding -
solve chemistry problems , which he published in 1916, also contained a cubic atom model. With this atomic model, the structures of ammonium and the diatomic chlorine molecule could also be clarified for the first time.
Lewis saw himself as an opponent of the dynamic atomic model -

In 1923, Lewis formulated his acid-base theory and in 1933 he devoted himself for the first time to the separation of isotopes. In the first year, he succeeded in producing an almost pure heavy hydrogen.
