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.
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. In the periodic table of the elements, it is expected to be the first of the superactinides, and the third element in the eighth period.

Sometimes, eka- is still used to refer to some of the transuranic elements, for example, eka-radium for unbinilium. But current official IUPAC practice is to use a systematic element name based on the atomic number of the element as the provisional name, instead of being based on its position in the periodic table as these prefixes require.
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.

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 ...
