Wilhelm Konrad Röntgen made an earth-shattering discovery for chemistry and atoms in 1895: He discovered x rays. Then, soon after, Henri Becquerel took the idea of x rays a step further and made another, equally earth-shattering discovery for chemistry and atoms: radioactivity. The Curies figured out which known elements were radioactive. Rutherford categorized radioactive rays into alpha, beta, and gamma. We explore what these rays are. We end up with the discovery of the neutron.<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!

31: What's Inside

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.
