Unbitrium, (meaning one-two-three-ium ) also known as eka-protactinium or element 123, is the hypothetical chemical element in the periodic table that has the temporary symbol Ubt and has the atomic number 123. According to Leonard Schiff (see section: Electron configuration), unbitrium would be the first element to have G electrons (Schiff predicts that unbiunium and unbibium will have only S electrons and D electrons .). Unbitrium is expected to be on an island of stability.

Naming
The name unbitrium is a systematic element name, used as a placeholder until it is confirmed by other research groups and the IUPAC decides on a name. Usually, the name suggested by the discoverer(s) is chosen.

Eka-protactinium
Unbitrium is also known as eka-protactinium, but unquadunium can also be known as eka-protactinium.

See Mendeleev's predicted elements.

Other names for unbitrium

 * Element 123
 * Dvi-praseodymium

Position in the periodic table
Unbitrium is expected to be in a new group of elements called superactinides. These should behave differently from other groups of elements. Unbitrium is also expected to be the lighter homologue of unsepttrium, the last possible neutral element (unless the Pyykkö model is correct).

Isotopes
Calculations have shown that 326Ubt would be the most stable isotope. The closed neutron shells say that 307Ubt and 319Ubt would be the most stable isotopes.

Synthesis
one attempt has ever been made to synthesize element 123.

This reaction would create 307Ubt, which is expected to be relatively stable.

Stablity

Target-projectile combinations leading to Z=123 compound nuclei
The below table shows various combinations of targets and projectiles leading to compound nuclei with an atomic number 123. .

Stable unbitrium
The only practical isotopes that would be longer-lived than others are 307Ubt and 319Ubt. They would be relatively stable. The equation above tells how to synthesize unbitrium-307. However, unbitrium is not expected to be the most stable element in the island of stability. Unbihexium is expected to be the most stable element on the island of stability.

Electron configuration
Leonard I. Schiff predicted that unbitrium would have the electron configuration [Uuo] 5g2 7d1. That means that unbitrium would be the first element to have g electrons.

Fictional Reference to Unbitrium (Element 123)
In the fictional universe of Star Trek: The Next Generation, this element was apparently discovered and named. The episode "Rascals" depicted a "trans-periodic table," in a schoolroom set, which depicted element number 123 as being named jamesium, symbol Rj, having an atomic weight of 326. The graphic was created by set artists, probably a homage to designer Richard D. James, and listed this element in the fictional "gamma series."
