The exhibition in a few words<\/h4>\n
Today an indispensable tool of chemistry, the periodic table of elements is celebrating its 150th anniversary this year. Brilliant intuition, as he likes to say, or the fruit of the legacy of chemists before him: how did Mendeleev arrive at this classification? How did it become established in the scientific world?<\/p>\n
Until the late 18th century, chemistry was strongly inspired by the theory of the four elements: fire, air, water and earth. On the eve of the Revolution, Antoine de Lavoisier radically changed this notion of element: it is now about the smallest possible division of a substance. This new definition is followed by a genuine quest for the discovery of elements, facilitated by the development of scientific instruments.<\/p>\n
As the list of elements grows, the question of their classification becomes a major concern for chemists. The possibility of a classification based on atomic mass gradually became apparent in the first half of the 19th century. We thus demonstrate the periodicity of their chemical properties. But the road is still long before the adoption of a classification recognized by all. Between 1862 and 1869, no less than six chemists proposed periodic tables, the first of which was the Telluric Vis by B\u00e9guyer de Chancourtois, a mining engineer.<\/p>\n
On the occasion of the International Year of the Periodic Table of Chemical Elements, the exhibition of the \u00c9cole des mines de Paris retraces through the history of its precursors, the formidable human and scientific adventure at the origin of this table.<\/p>\n
