The Periodic Table of Elements, also known as Mendeleev’s table, is a tabled structure that includes all of the chemical elements that exist on Earth. It was created by Dmitri Mendeleev in 1869 and has been added to over the years as new elements have been discovered. Mendeleev’s table is an amazing creation and was quickly adopted by chemists all over the world due to the way it is displayed; the elements are ordered into patterns dependant on the chemical properties each one possesses and thus its expected behaviour No previous representation even came close to achieving this.
2019 marks 150 years since Mendeleev devised the Periodic System. With the support of the International Union of Pure and Applied Chemistry (IUPAC), the European Chemical Society (EuChemS), the International Union of History and Philosophy of Science and Technology (IUHPST), the International Science Council and the International Union of Pure and Applied Physics (IUPAP) 2019 has been branded the International Year of the Periodic table or IYPT for short!
