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. In the periodic table of the elements, it is expected to be an s-block element, an alkaline earth metal, and the second element in the eighth period.

Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.
The first letter is always capitalized. While the symbol is often a contraction of the element's name, it may sometimes not match the element's English name; for example, "Pb" for lead (from Latin plumbum) or "W" for tungsten (from German Wolfram). Elements which have only temporary systematic names are given temporary three-letter symbols (e.g ...
32 of these have names tied to the Earth and the other 10 have names connected to bodies in the Solar System. The first tables below list the terrestrial locations (excluding the entire Earth itself, taken as a whole) and the last table lists astronomical objects which the chemical elements are named after.

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 ...
