This year, the idea of the Periodic Table of Elements celebrates its 150th anniversary, a fact that is recognized all around the world. To bring attention the the importance and development of this scientific breakthrough, a series of talks are held at SLU.
In the talk, we will follow the development of the idea of what a chemical element is and how they can be discovered. By following some exciting stories from the history of chemistry, the talk explores the discovery of some elements, and how some of them turned out not to be elements at all.
Analytical chemistry is an important field when it comes to identifying chemical substances. Thus, the talk will also raise topics of the development of methods that permit us to “see” atoms and molecules, and understand their behavior – from taste and smell to advanced instruments.
