Se numero vaikuttaa niin isolta, että uskosin, että sillä on semmonen väliaikasen kuulonen nimi, yksiyksiviisium tai vastaavaa.
Unununium.

- Tue 29.03.2011 10:34:38 (UTC+0300)Ununpentium (/uːnuːnˈpɛntiəm/ oon-oon-PEN-tee-əm) is the temporary name of a synthetic superheavy element in the periodic table that has the temporary symbol Uup and has the atomic number 115.
It is placed as the heaviest member of group 15 (VA) although a sufficiently stable isotope is not known at this time that would allow chemical experiments to confirm its position. It was first observed in 2003 and only about 30 atoms of ununpentium have been synthesized to date, with just 4 direct decays of the parent element having been detected. Four consecutive isotopes are currently known, 287-290Uup, with 289Uup having the longest measured half-life of ~220 ms, although the isotope 290Uup may well have an even longer half-life (only a single decay has been measured leading to poor accuracy).
Ununpentium is historically known as eka-bismuth. Ununpentium is a temporary IUPAC systematic element name. Research scientists usually refer to the element simply as element 115.
