DESCRIPTION:The discovery of the periodic system is often associated with 
 the Russian chemist Dmitrii Ivanovich Mendeleev. While Mendeleev was not t
 he only chemist developing periodic classifications of the chemical elemen
 ts\, Mendeleev stood out from other chemists by making highly accurate pre
 dictions of unknown elements. The story of Mendeleev's accurate prediction
 s is well rehearsed\, but Mendeleev's methods in making predictions are le
 ss familiar. In this talk\, I will explain how Mendeleev predicted propert
 ies of little-known element indium and completely unknown element ekaboron
  (scandium) with the use of his periodic system. I will then contrast thes
 e predictions with Mendeleev’s less-successful predictions of coronium a
 nd ether – two chemical elements that we are yet to be discovered.\n\nSp
 eaker bio: I am a final year PhD student at the Department of History and 
 Philosophy of Science here at Cambridge. In my research\, I apply the fram
 ework of values to analyse a well-known priority dispute concerning the di
 scovery of the periodic system. By doing so\, my project maps the role of 
 values in the  practice of chemistry. Before starting my studies at Cambri
 dge\, I did my Bachelors degree in the University of Glasgow. Lunchtime re
 gulars at Darwin might recognise me as the Finn with a slight Scottish twa
 ng.
