Marking the 150th anniversary of Dmitri Mendeleev’s discovery of the periodic system, 2019 is the International Year of the Periodic Table (IYPT). We look forward to sharing and celebrating the IYPT with all our readers this year.
Dmitri Mendeleev (1834–1907), a Russian chemist and inventor, is credited with the discovery of the periodic system of chemical elements in 1869.
The periodic table is a talking point for scientists around the world.

Listen to stories about all 118 elements on the periodic table.
Labs around the world are racing to create new 'superheavy' elements. Elements 113, 115, 117 and 118 (nihonium, moscovium, tennessine and oganesson) were confirmed in late 2015. When will we see the next new element on the periodic table?
Try our interactive presentation based on the Royal Society of Chemistry's public attitudes to chemistry survey.
First recorded by Tom Lehrer in 1959 (when there were only 102 elements on the periodic table) it has since been covered, and updated, by many scientists and musicians over the years.
