2019 is the International Year of the Periodic Table of Chemical Elements, marking 150 years since Dmitri Mendeleev devised a system to arrange the elements.

Join Annie Hodgson of the University of York as she introduces an exhibition celebrating the history and future of this icon of chemistry.

 

Find out about the timeline of the 118 elements from those known by ancient civilisations to those most recently created in particle accelerators.

While Mendeleev was not the first chemist to seek order among the known elements, he succeeded by leaving gaps for elements yet to be discovered. Since 1869 Mendeleev’s table has been completed and other scientists have offered alternative methods to display the elements. Come along and discover the meaning behind these arrangements and consider whether the periodic table is truly complete or whether there are more elements yet to be found.

Following the talk (7pm to 7.30pm), there will an opportunity to look around the exhibition. Refreshments will be served.
