The most important was thermodynamics, a subject in which Richards was very active at that time. Although most of the important thermodynamic relations were known by 1895, they were seen as isolated equations, and had not yet been rationalized as a logical system, from which, given one relation, the rest could be derived. Moreover, these relations were inexact, applying only to ideal chemical systems. These were two outstanding problems of theoretical thermodynamics. In two long and ambitious theoretical papers in 1900 and 1901, Lewis tried to provide a solution. Lewis introduced the thermodynamic concept of <a href="/wiki/Activity_(chemistry)" class="mw-redirect" title="Activity (chemistry)">activity</a> and coined the term "<a href="/wiki/Fugacity" title="Fugacity">fugacity</a>".<sup id="cite_ref-35" class="reference"><a href="#cite_note-35"><span class="cite-bracket">[</span>35<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-36" class="reference"><a href="#cite_note-36"><span class="cite-bracket">[</span>36<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-37" class="reference"><a href="#cite_note-37"><span class="cite-bracket">[</span>37<span class="cite-bracket">]</span></a></sup> His new idea of fugacity, or "escaping tendency",<sup id="cite_ref-38" class="reference"><a href="#cite_note-38"><span class="cite-bracket">[</span>38<span class="cite-bracket">]</span></a></sup> was a function with the dimensions of <a href="/wiki/Pressure" title="Pressure">pressure</a> which expressed the tendency of a substance to pass from one chemical phase to another. Lewis believed that fugacity was the fundamental principle from which a system of real thermodynamic relations could be derived. This hope was not realized, though fugacity did find a lasting place in the description of real gases. </p><p>Lewis’ early papers also reveal an unusually advanced awareness of <a href="/wiki/Josiah_Willard_Gibbs" title="Josiah Willard Gibbs">J. W. Gibbs's</a> and <a href="/wiki/Pierre_Duhem" title="Pierre Duhem">P. Duhem's</a> ideas of free energy and <a href="/wiki/Thermodynamic_potential" title="Thermodynamic potential">thermodynamic potential</a>. These ideas were well known to physicists and mathematicians, but not to most practical chemists, who regarded them as abstruse and inapplicable to chemical systems. Most chemists relied on the familiar thermodynamics of heat (enthalpy) of <a href="/wiki/Marcellin_Berthelot" title="Marcellin Berthelot">Berthelot</a>, <a href="/wiki/Wilhelm_Ostwald" title="Wilhelm Ostwald">Ostwald</a>, and <a href="/wiki/Jacobus_Henricus_van_%27t_Hoff" title="Jacobus Henricus van 't Hoff">Van ’t Hoff</a>, and the <a href="/wiki/Calorimetry" title="Calorimetry">calorimetric</a> school. Heat of reaction is not, of course, a measure of the tendency of chemical changes to occur, and Lewis realized that only free energy and entropy could provide an exact chemical thermodynamics. He derived free energy from fugacity; he tried, without success, to obtain an exact expression for the <a href="/wiki/Entropy" title="Entropy">entropy</a> function, which in 1901 had not been defined at low temperatures. Richards too tried and failed, and not until Nernst succeeded in 1907 was it possible to calculate entropies unambiguously. Although Lewis’ fugacity-based system did not last, his early interest in <a href="/wiki/Thermodynamic_free_energy" title="Thermodynamic free energy">free energy</a> and entropy proved most fruitful, and much of his career was devoted to making these useful concepts accessible to practical chemists. </p><p>At Harvard, Lewis also wrote a theoretical paper on the thermodynamics of <a href="/wiki/Blackbody_radiation" class="mw-redirect" title="Blackbody radiation">blackbody radiation</a> in which he postulated that light has a pressure. He later revealed that he had been discouraged from pursuing this idea by his older, more conservative colleagues, who were unaware that <a href="/wiki/Wilhelm_Wien" title="Wilhelm Wien">Wilhelm Wien</a> and others were successfully pursuing the same line of thought. Lewis’ paper remained unpublished; but his interest in radiation and <a href="/wiki/Quantum_mechanics" title="Quantum mechanics">quantum theory</a>, and (later) in <a href="/wiki/Theory_of_relativity" title="Theory of relativity">relativity</a>, sprang from this early, aborted effort. From the start of his career, Lewis regarded himself as both chemist and physicist. </p> <div class="mw-heading mw-heading3"><h3 id="Valence_theory">Valence theory</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Gilbert_N._Lewis&action=edit&section=8" title="Edit section: Valence theory"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:Lewis-cubic-notes.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/en/thumb/3/32/Lewis-cubic-notes.jpg/300px-Lewis-cubic-notes.jpg" decoding="async" width="300" height="336" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/en/thumb/3/32/Lewis-cubic-notes.jpg/450px-Lewis-cubic-notes.jpg 1.5x, //upload.wikimedia.org/wikipedia/en/thumb/3/32/Lewis-cubic-notes.jpg/600px-Lewis-cubic-notes.jpg 2x" data-file-width="1179" data-file-height="1322" /></a><figcaption>Lewis' <b><a href="/wiki/Cubical_atom" title="Cubical atom">cubical atoms</a></b> (as drawn in 1902)</figcaption></figure> <p>About 1902 Lewis started to use unpublished drawings of <a href="/wiki/Cubical_atom" title="Cubical atom">cubical atoms</a> in his lecture notes, in which the corners of the cube represented possible <a href="/wiki/Electron" title="Electron">electron</a> positions. Lewis later cited these notes in his classic 1916 paper on chemical bonding, as being the first expression of his ideas. </p><p>A third major interest that originated during Lewis’ Harvard years was his valence theory. 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. This “cubic atom” explained the cycle of eight elements in the periodic table and was in accord with the widely accepted belief that chemical bonds were formed by transfer of electrons to give each atom a complete set of eight. This electrochemical theory of valence found its most elaborate expression in the work of <a href="/wiki/Richard_Abegg" title="Richard Abegg">Richard Abegg</a> in 1904,<sup id="cite_ref-39" class="reference"><a href="#cite_note-39"><span class="cite-bracket">[</span>39<span class="cite-bracket">]</span></a></sup> but Lewis’ version of this theory was the only one to be embodied in a concrete atomic model. Again Lewis’ theory did not interest his Harvard mentors, who, like most American chemists of that time, had no taste for such speculation. Lewis did not publish his theory of the cubic atom, but in 1916 it became an important part of his theory of the shared electron pair bond. </p><p>In 1916, he published his classic paper on chemical bonding "<i>The Atom and the Molecule</i>"<sup id="cite_ref-40" class="reference"><a href="#cite_note-40"><span class="cite-bracket">[</span>40<span class="cite-bracket">]</span></a></sup> in which he formulated the idea of what would become known as the <a href="/wiki/Covalent_bond" title="Covalent bond">covalent bond</a>, consisting of a <a href="/wiki/Shared_pair" class="mw-redirect" title="Shared pair">shared pair</a> of electrons, and he defined the term odd molecule (the modern term is <a href="/wiki/Free_radical" class="mw-redirect" title="Free radical">free radical</a>) when an electron is not shared. He included what became known as <a href="/wiki/Lewis_structure" title="Lewis structure">Lewis dot structures</a> as well as the <a href="/wiki/Cubical_atom" title="Cubical atom">cubical atom</a> model.
