Ununoctium is the temporary name of an undiscovered chemical element in the periodic table that has the temporary symbol Uuo and has the atomic number 118.
The name Ununoctium is used as a placeholder, such as in scientific articles about the search for Element 118; it is a Latinate way of saying "one-one-eight-ium" ("ium" being a standard ending for element names). Such transuranic elements are always artificially produced, and usually end up being named for a scientist. See Element naming controversy, systematic element name.
