Ununtrium (Uut). Diagram of the nuclear composition,electron configuration,chemical data,and valence (outer electron) orbitals of an atom of ununtrium-284 (atomic number: 113),an isotope of this radioactive element. The nucleus consists of 113 protons (red) and 171 neutrons (orange). 113 electrons (white) successively occupy available electron shells (rings). Ununtrium is a temporary name (2003 synthesis not yet official). It is a transactinide of unknown properties in group 13,period 7,and the p-block of the periodic table. Ununtrium-284 has a half-life of 0.48 seconds | |
