Ununpentium is the temporary name of an undiscovered
chemical element in the
periodic table that has the temporary symbol Uup and has the atomic number 115.
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
