Element 117 (Tennessine)

Tennessine (Element 117) is a synthetic, highly radioactive element created in laboratories through nuclear reactions. It belongs to the halogen group, similar to fluorine and iodine, but it is extremely unstable and exists for only fractions of a second. Its name honors Tennessee, where it was first synthesized. Due to its fleeting existence, Tennessine’s chemical properties are not fully understood, but it is primarily used in scientific research to explore the behavior of superheavy elements and understand nuclear stability at extreme atomic numbers.
