Oganesson is a synthetic chemical element with the symbol Og and atomic number 118. It is the heaviest element on the periodic table and is highly radioactive and unstable. Oganesson is classified as a member of the noble gases group.

Key Characteristics of Oganesson:

1. Synthetic Production: Oganesson does not occur naturally and can only be produced in a laboratory through nuclear reactions. It is typically created by bombarding a target element with a beam of high-energy particles, such as heavy ions.
2. Radioactivity: Oganesson is highly radioactive and exhibits extremely short half-lives for its isotopes. Its most stable isotope, Oganesson-294, has a half-life estimated to be less than a microsecond.
3. Chemical Properties: Due to its high atomic number, Oganesson is expected to be a noble gas and exhibit similar chemical properties to other elements in the same group, such as helium, neon, and xenon. However, due to its synthetic nature and extremely limited availability, detailed studies of its chemical properties have been challenging.
4. Naming: Oganesson is named after Russian physicist Yuri Oganessian, who made significant contributions to the discovery of superheavy elements.
5. Applications: Oganesson has no practical applications beyond scientific research due to its highly unstable and short-lived nature. Its study is primarily of scientific interest for understanding the behavior and properties of superheavy elements.

Due to its synthetic and highly radioactive properties, Oganesson’s applications are limited to scientific research and the exploration of nuclear physics. Its production and study contribute to our understanding of nuclear reactions, atomic structure, and the stability of heavy elements.
