Ununoctium (Uuo). Diagram of the nuclear composition,electron configuration,chemical data,and valence (outer electron) orbitals of an atom of ununoctium-294 (atomic number: 118),the only known isotope of this radioactive element. The nucleus consists of 118 protons (red) and 176 neutrons (orange). 118 electrons (white) successively occupy available electron shells (rings). Ununoctium is a temporary name (2002 synthesis not yet official). It is a transactinide of unknown properties in group 18,period 7,and the p-block of the periodic table. The ununoctium-294 nucleus (half-life: 0.89 milliseconds) emits an alpha particle to form ununhexium-290 | |
