Element Story - Oganesson

Oganesson is the element with atomic number 118, a superheavy element with the highest atomic number officially confirmed to date. It belongs to Group 18 of the periodic table, and all known isotopes are radioactive and do not exist in nature. It was synthesized in 2002 through a joint research effort between the Joint Institute for Nuclear Research in Dubna, Russia, and Lawrence Livermore National Laboratory in the United States, and was named after Yuri Oganessian, a pioneer in superheavy element research. Oganesson is produced in extremely small quantities and has a very short half-life, so it is not used in daily life or industry. It is primarily used to study the nuclear structure and radioactive decay of superheavy elements. Although it belongs to Group 18, its very large atomic number causes relativistic effects to strongly influence its electron configuration. Therefore, unlike other noble gases, it is predicted to have relatively high reactivity, and research is ongoing into the possibility that it may not be a gas at room temperature. Oganesson, as the last element on the current periodic table, is an important research subject for exploring the island of stability for superheavy elements and the possibility of new elements.
