Unbinilium, also known as eka-radium or element 120, is a hypothetical chemical element; it has symbol Ubn and atomic number 120. Unbinilium and Ubn are the temporary systematic IUPAC name and symbol , which are used until the element is discovered, confirmed, and a permanent name is decided upon.
Cryptic crosswords often use abbreviations to clue individual letters or short fragments of the overall solution. These include: Any conventional abbreviations found in a standard dictionary, such as: "current": AC (for "alternating current"); less commonly, DC (for "direct current"); or even I (the symbol used in physics and electronics)
Jens Volker Kratz predicted the actual maximum cross section for producing unbinilium by any of the four reactions 238 U+ 64 Ni, 244 Pu+ 58 Fe, 248 Cm+ 54 Cr, or 249 Cf+ 50 Ti to be around 0.1 fb; [21] in comparison, the world record for the smallest cross section of a successful reaction was 30 fb for the reaction 209 Bi(70 Zn,n) 278 Nh, [11 ...

Unbiunium, also known as eka-actinium or element 121, is a hypothetical chemical element; it has symbol Ubu and atomic number 121. Unbiunium and Ubu are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.
A systematic symbol is also derived from this name. In chemistry, a transuranic element receives a permanent name and symbol only after its synthesis has been confirmed. In some cases, such as the Transfermium Wars, controversies over the formal name and symbol have been protracted and highly political.
