Unbipentum, also known as element 125 or eka-neptunium, is the hypothetical chemical element in the periodic table with the placeholder symbol of Ubt and atomic number 125^[2]. Unbipentium and Ubp are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon. In the periodic table of the elements, it is expected to follow unbiquadium as the second element of the superactinides and the fifth element of the 8th period. Similarly to unbibium and unbiunium, it is expected to fall within the range of the island of stability.

Since there are no natural isotopes of this element, it would have to be generated (synthesized) in an artificial way through nuclear reactions. The name is provisional and is derived from the ordinal number. As of 2022, the synthesis of unbipentium has only been attempted once, and no naturally occurring isotopes have been found to exist. There are currently no plans to attempt to synthesize unbipentium.

Unbipentium is expected to be in a new group of elements called superactinides^[3]. These should behave differently from other groups of elements.

Chemically, unbipentium is expected to show some resemblance to promethium and neptunium. However, due to relativistic effects, some of these properties may differ from expected. Unbipentium is possibly the fifth element to have a G orbital, which would fill the 5th shell with three additional electrons.
