If discovered, it would probably share the properties of its group, the noble gases, resembling radon in its chemical properties; as such, some research has referred to it as "eka-radon". It would only be the second radioactive gaseous element and the first standard semiconductive gas.

History
In 1999, researchers at Lawrence Berkeley National Laboratory announced the discovery of elements 116 and 118, in a paper published in Physical Review Letters. The following year, they published a retraction after other researchers were unable to duplicate the results. In June 2002, the director of the lab announced that the original claim of the discovery of these two elements had been based on data fabricated by principal author Victor Ninov. 1999 is a common year starting on Friday of the Common Era, and was designated the International Year of Older Persons by the United Nations. ...

Accurentum (Ac) In the fictional universe of Star Trek: The Next Generation, the episode "Rascals" depicted a trans-periodic table, which depicted element number 118 as being named accurentum. A fictional universe is a cohesive fictional world that serves as the setting or backdrop for one or (more commonly) multiple works of fiction. ...

The Star Trek chemical symbol for Accurentum, Ac, conflicts with actinium. Star Trek collectively refers to six science fiction television series spanning 726 episodes, ten motion pictures, and hundreds of novels, video games, and other works of fiction all set within the same fictional universe created by Gene Roddenberry in the early- to mid-1960s. ...
