![]() GSI has already named their officially recognized elements 107 to 111: element 107 is called Bohrium, element 108 Hassium, element 109 Meitnerium, element 110 Darmstadtium, and element 111 is named Roentgenium. ![]() Please note that the elements do not show their natural relation towards each other as in the Periodic system. Since 1981, GSI accelerator experiments have yielded the discovery of six chemical elements, which carry the atomic numbers 107 to 112. The first chemical element is Actinium and the last is Zirconium. It is the 112 electrons, which orbit the nucleus, that determine the new element’s chemical properties. The neutrons that are also located in the nucleus have no effect on the classification of the element. An element’s atomic number indicates the number of protons in its nucleus. Its so-called atomic number 112, hence the provisional name “element 112”, is the sum of the atomic numbers of the two initial elements: zinc has the atomic number 30 and lead the atomic number 82. The zinc and lead nuclei merge in a nuclear fusion to form the nucleus of the new element. To produce element 112 atoms, scientists accelerate charged zinc atoms – zinc ions for short – with the help of the 120 m long particle accelerator at GSI and “fire” them onto a lead target. Subsequent accelerator experiments at the Japanese RIKEN accelerator facility produced more atoms of element 112, unequivocally confirming GSI’s discovery. In 2002, they were able to produce another atom. It is a graphic formulation of the periodic law, which states that the properties of the chemical elements exhibit a periodic dependence on their atomic numbers.

Here's a list of all of the chemical elements of the periodic table ordered by increasing atomic number. A chemical element, often simply called an element, is a type of atom which has the same number of protons in its atomic nucleus (i.e., the same atomic number, or Z ). ![]() During the next few weeks, the scientists of the discovering team will deliberate on a name for the new element”, says Sigurd Hofmann. List of chemical elements This is a list of the 118 chemical elements which have been identified as of 2022. Click on Development of the periodic table to learn about the scientists involved in the tables creation. “We are delighted that now the sixth element – and thus all of the elements discovered at GSI during the past 30 years – has been officially recognized. Hover over an element to find out about its discovery and click on it for more information. The new element is approximately 277 times heavier than hydrogen, making it the heaviest element in the periodic table. In about 6 months, after the proposed name has been thoroughly assessed by IUPAC, the element will receive its official name. Their suggestion will be submitted within the next weeks. ![]()
