On December 20, 2017 the United Nations General Assembly declared 2019 as the International Year of the Periodic Table of Chemical Elements, according to the International Union of Pure & Applied Chemistry.
1869 is "is considered as the year of discovery of the Periodic System by Dmitri Mendeleev," according to the IYPT website of the United Nations. This makes 2019 the 150th anniversary of the Periodic Table.
The IYPT website describes the Periodic Table as "one of the most significant achievements in science, capturing the essence not only of chemistry, but also of physics and biology."
Elements in the table are arranged from left ot right and top to bottom in order of increasing atomic number. The rows of elements are called periods, hence the name of the table. For more information on the table, click here.
