International Year of the Periodic Table of Chemical Elements (IYPT2019) is proclaimed as a year to celebrate the 150th anniversary on the discovery of periodicity in the chemical properties of elements.
Why we celebrate？In 2016, IUPAC approved the name of four new elements: 113 Nihonium (Nh), 115 Moscovium (Mc), 117 Tennessine (Ts), and 118 Oganesson (Og). Thus, the following new periodic table was released, leading to complete filling all elements down to period 7. This is one of the motivations to celebrate the year. Another is to celebrate the 150th anniversary on the discovery of the periodicity of elements by Dmitri Mendeleev.
Discovery of Nihonium is also a great honor for us. Actually, it is the first element ever discovered in Japan, and even the first one declared from Asia.
Initiation and Activities:A memorial project celebrating IYPT2019 was approved by the joint proposal of IUPAC, IUPAP (International Union of Pure and Applied Physics), IAU (International Astronomical Union), IUHPST (International Union of History and Philosophy of Science and Technology), and EuCheMS (European Chemical Society). These networks will actively promote the IYPT2019, through various activities and events at the world wide scale. The official Opening Ceremony of IYPT2019 will be held at UNESCO in Paris, January 29, 2019. A Special Symposium on IUPAC2019 is also planned to be held in Paris in July 2019. What's really valuable and honor for us is to take the privilege to hold the UNESCO-endorsed Closing Ceremony of IYPT2019 in Tokyo, Japan at the end of 2019. The planning committee for this international event is established within the Chemical Society of Japan and started to make the plan under the strong leadership by Dr. Kohei Tamao, in association with the president of the Chemical Society of Japan, Dr. Maki Kawai.
IUPAC100？ As it happens, the Centenary of IUPAC will also occur in 2019. The events of IUPAC100 and IYPT2019 will be held concurrently.
