Unbipentium, also known as eka-neptunium or more generally as element 125, is the hypothetical chemical element bearing the symbol Ubp and atomic number 125. Unbipentium and Ubp are the temporary IUPAC name and symbol, respectively, which are used until the element is discovered, confirmed and a permanent name is decided upon.
