Unbinilium is the temporary name of an undiscovered
chemical element in the
periodic table that has the temporary symbol Ubn and has the atomic number 120.
The name Unbinilium is used as a placeholder, such as in scientific articles about the search for Element 120; it is a
Latinate way of saying "one-two-naught-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.
