World’s Oldest Periodic Table Found In Storage
The oldest known periodic table in world has been discovered at the University of St Andrews. Dated back to 1885, the table was created only 16 years after Russian chemist Dmitri Mendeleev introduced the concept in 1869. According to Eric Scerri, an expert on the history of the periodic table based at the University of California, Los Angeles, the chart can be dated back to a time period between 1879 and 1886. “The discovery of the world’s oldest classroom periodic table at the University of St Andrews is remarkable,” says David O’Hagan, recent ex-head of chemistry at the University of St Andrews, in a press statement. “The table will be available for research and display at the University and we have a number of events planned in 2019, which has been designated international year of the periodic table by the United Nations, to coincide with the 150th anniversary of the table’s creation by Dmitri Mendeleev.”
