History The name Ununpentium is used as a placeholder, such as in scientific articles about the search for Element 115; it is a Latinate way of saying "one-one-five-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.
