<p>The concept was formulated in 1904 by German chemist <a href="/facts/Richard_Abegg/fa9mhL56">Richard Abegg</a>.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a>  <a href="/facts/Gilbert_N._Lewis/wWnV6QXL">Gilbert N. Lewis</a> was one of the first to refer to the concept as "Abegg's rule" when he used it as a basis of argument in a 1916 article to develop his <a href="/facts/Cubical_atom/ajNtecop">cubical atom</a> theory, which developed into the <a href="/facts/Octet_rule/X9jxSsos">octet rule</a>.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a>  That article helped inspire <a href="/facts/Linus_Pauling/cBNBzs5c">Linus Pauling</a> to write his 1938 textbook <i>The Nature of the Chemical Bond</i>.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a>
