'''Unbipentium''', also known as eka-], is the hypothetical chemical element with the atomic number 125 and symbol Ubp. Calculations predict that <sup>332</sup>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 (UbpF<sub>6</sub>) like neptunium. |
|
|
|
|
|
==Electron configuration== |
|
|
|
|
|
Leonard I. Schiff predicted that unbipentium will have the electron configuration 8s<sup>2</sup> 7d<sup>1</sup> 5g<sup>4</sup>. |
