Superheavy elements are chemical elements with atomic numbers greater than 104. These elements are not found naturally and must be created in laboratories through nuclear reactions. They are typically unstable and have very short half-lives, making them difficult to study. The most well-known superheavy elements include copernicium, livermorium, and oganesson. Scientists explore these elements to understand the limits of the periodic table and the forces that hold atomic nuclei together. Research on superheavy elements can also provide insights into the behavior of matter under extreme conditions.
