The International Mendeleev Olympiad (IMO) for high school students in chemistry starts tomorrow, April 21st, reports the Russian Ministry of Foreign Affairs. The tournament is named after Dmitry Mendeleev. This year marks the 190th anniversary of the birth of the great Russian scientist, the author of the Periodic Table of Chemical Elements. The competition for young chemists will take place for the fifty-sixth time. For the first time, the contest will be held outside the CIS. It is hosted by China. The venue will be the Russian-Chinese University of MSU-PPI, operating in Shenzhen. About three hundred people will gather there. High school students and their mentors represent more than thirty countries. Russia is represented by the top ten participants of the All-Russian Chemistry Olympiad for high school students, who scored the highest points, from seven regions. The Russian team includes students from Altai Krai, Nizhny Novgorod, Novosibirsk, and Samara regions, from Moscow, Bashkiria, and Tatarstan. For them, this event will be their first practical experience of international scientific cooperation. As “Russian World” reported, the International Mendeleev Olympiad (IMO) in 1997 became the legal successor of the All-Union Chemistry Olympiad for high school students, preserving its numbering. The tasks, which are developed by the scientists from MSU, are traditionally more complex than those given at the International Chemistry Olympiad. They require not only theoretical preparation but also teamwork skills and a creative approach. The Olympiad consists of three rounds: two theoretical and one practical.
