Mendeleev left spaces for elements he expected to be discovered, and today’s periodic table contains 118 elements, starting with hydrogen and ending with oganesson, a chemical element first synthesized in 2002 at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, by a team of Russian and American scientists. The Chemistry Division's Periodic Table describes the history, properties, resources, uses, isotopes, forms, costs, and other information for each element. The periodic table of the elements was first introduced in the mid-19th century by Dmitry Mendeleev. He organized the elements by atomic number, which is equal to the number of protons found in the nucleus of the element’s atoms. Check out the periodic table of elements.
