Unbipentium (pronounced /ˌʌnbɨˈpɛntiəm/), or eka-neptunium, is the temporary name of an undiscovered chemical element in the periodic table that has the temporary symbol Ubp and has the atomic number 125.
[edit] History
The name unbipentium is used as a placeholder, such as in scientific articles about the search for element 125. Transuranic elements beyond plutonium are always artificially produced, and usually end up being named for a scientist or the location of a laboratory that does work in atomic physics.
Element 125 is of interest because it is within a range that has been predicted [1] to be within a range of experimentally feasible "island of stability" elements based on a mean field theory based on a model of alpha decay.
The article, in the peer-reviewed Physical Review Journal, argued that the self-coupling of the omega meson could be responsible for greater shell stability based earlier work, which suggested that self-coupling meson effects were stronger than originally predicted.
The name Golver has been suggested in scientific circles, but IUPAC have yet to formally recognize the name.
