Unbipentium, also known as eka-neptunium, is the hypothetical chemical element with the atomic number 125 and symbol Ubp. Calculations predict that Ubp would be the most stable unbipentium isotope. To date, no attempt has ever been made to synthesize element 125.

Naming

The name unbipentium 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.

Predicted chemistry

Unbipentium might be extremely reactive and similar to neptunium. A likely oxidation sttate is +7 (based on that of neptunium). It might form a hexafluoride (UbpF₆) like neptunium.

Electron configuration

Leonard I. Schiff predicted that unbipentium will have the electron configuration 8s 7d 5g.
