Unbibium, also known as element 122 or eka-thorium, is a hypothetical chemical element; it has placeholder symbol Ubb and atomic number 122. Unbibium and Ubb 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.

They also planned to further chart the region by investigating the nearby compound nuclei 296 Og*, 298 Og*, 306 Ubb*, and 308 Ubb*. [ 93 ] The most likely isotopes of unbinilium to be synthesised in the near future are 295 Ubn through 299 Ubn, because they can be produced in the 3n and 4n channels of the 249–251 Cf+ 50 Ti, 245 Cm+ 54 Cr, and ...
It has also been posited that this region of enhanced stability for elements with 112 ≤ Z ≤ 118 may instead be a consequence of nuclear deformation, and that the true center of the island of stability for spherical superheavy nuclei lies around 306 Ubb (Z = 122, N = 184). [20]
