Unbiseptium
There could be a chemical element with 127 protons and 127 electrons in each of its atoms. Scientists call it Unbiseptium, /ˌuːnbaɪˈsɛptiəm/, eka-americium[source?], Element 127 for now and have given it the chemical symbol Ubs.[1] If this thing is found one day, they will pick a new name for it.
Naming
The name unbiseptium is a systematic element name, used as a placeholder until its discovery is confirmed. Transuranium elements beyond californium are always created artificially, and the element usually ends up being named for a scientist or a laboratory that does work in atomic physics.[source?]
Making
In 1978, scientists tried to make Unbiseptium by trying to hit tantalum with xenon ions inside the Darmstadt UNILAC accelerator, but failed.[2]

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 (---)
