Unbiseptium

Unbiseptium, /ˌuːnbaɪˈsɛptiəm/, eka-americium ^[1] or just Element 127 is a proposed element with 127 electrons and 127 protons. They have given it the chemical symbol Ubs.^[2] If this element is found one day, the discoverers of the element will pick a new name for it according to a set of names that IUPAC suggested.^[3] It would be a "superheavy" element that would belong in a section of the periodic table called the g-block if made.

Naming

The name Unbiseptium that was chosen for Element 127 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.^[4]

Making

Scientists have tried to make this element by crashing smaller atoms into each other at very high speeds. In 1978, a group of scientists in Germany used a machine to fire xenon atoms at a metal atom called tantalum. They hoped the two types of atoms would join together to form Element 127. But the experiment failed and the element was not created. Scientists are still trying to find new ways to make it using even more powerful machines.^[5]

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.
