The element that currently has no symbol in its name is element 118. It is a synthetic element with the temporary systematic name "ununoctium" (symbol Uuo), which is derived from the Latin for "one-one-eight." However, element 118 does not have an officially approved symbol yet.
Element 118 was first synthesized in 2002 by a team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, and the Lawrence Livermore National Laboratory in California, USA. It was created by bombarding a target of curium-248 with calcium-48 ions, resulting in the formation of the element with atomic number 118.
Due to its highly unstable and short-lived nature, element 118 has only been produced in very small quantities and has a very short half-life. Its chemical properties are not yet well-known, and further research is required to fully understand its characteristics.
It is important to note that the naming and symbol for element 118 are subject to approval by the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP). Until an official name and symbol are determined, it is commonly referred to as element 118 or ununoctium.
