Radiochemistry is the chemistry of radioactive materials, where radioactive isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes (often within radiochemistry the absence of radioactivity leads to a substance being described as being inactive as the isotopes are stable ).
The World of Chemistry is a television series on introductory chemistry hosted by Nobel prize-winning chemist Roald Hoffmann.The series consists of 26 half-hour video programs, along with coordinated books, which explore various topics in chemistry through experiments conducted by Stevens Point emeritus professor Don Showalter the "series demonstrator" [1] and interviews with working chemists ...
