Charles Barkla realized how electrons arrange themselves in shells around atoms. Gilbert Lewis noted how electrons can pair up and form bonds, without (much) regard for willingness to give up or accept other electrons to complete shells. We discuss polarity of molecules. Irving Langmuir promoted and expanded Lewis&apos;s ideas, adding that atoms like to form octets. Finally, we discuss various models of acidity and basicity.<a rel="payment" href="https://www.patreon.com/thehistoryofchemistry">Support the Show.</a><ul> <li>Support my podcast at <a href='https://www.patreon.com/thehistoryofchemistry'>https://www.patreon.com/thehistoryofchemistry</a> </li> <li>Tell me how your life relates to chemistry!

33: I Want a New Drug

Chemistry is everywhere, and involves everything. But how did chemistry get to be what it is? I'm Steve Cohen, a chemist and writer, bringing you The History of Chemistry. This podcast explores the development of chemistry from prehistoric times to the present, including the people and societies who made chemistry what it is today. The History of Chemistry is for you, whether you hated chemistry in high school, or got a PhD in inorganic chemistry. We'll explore how chemistry affected art, music, language, politics and vice-versa. Whether it's ancient Greek philosophers, medieval alchemists, or modern laboratory apparatus, it's all here.
