Superactinide
The superactinides are a group of hypothetical elements that are predicted to be elements 121-156. One of these elements is expected to have a magic number of protons and neutrons which is unbihexium. unbihexium is expected to have 126 protons and 184 neutrons.

Further Information: Unbiunium
Unbiunium was attempted to be synthesized in 1977 by shooting Copper-65 at Uranium-238. it was unsuccessful and no atoms were indentified.
Unbibium
Further Information: Unbibium
Unbibium was attempted to be synthesized in 1972 by shooting Zirconium-66 and 68 at Uranium-238. it was unsuccessful. no atoms were detected. Unbibium is predicted to be in the island of stability.

Energy eigenvalues (in eV) for the outermost electrons of elements with Z = 100 through 172, predicted using Dirac–Fock calculations. The − and + signs refer to orbitals with decreased or increased azimuthal quantum number from spin–orbit splitting respectively: p− is p1/2, p+ is p3/2, d− is d3/2, d+ is d5/2, f− is f5/2, f+ is f7/2, g− is g7/2, and g+ is g9/2.
Energy eigenvalues for the 1s, 2s, 2p1/2 and 2p3/2 shells from solutions of the Dirac equation (taking into account the finite size of the nucleus) for Z = 135–175 (–·–), for the Thomas-Fermi potential (—) and for Z = 160–170 with the self-consistent potential (---).
