                                    Bohrium: the essentials

                                    Bohrium atoms have 107 electrons and the shell structure is 2.8.18.32.32.13.2. The ground state electronic configuration of neutral bohrium is [Rn].5f14.6d5.7s2 (a guess based upon that of rhenium) and the term symbol of bohrium is 6S5/2 (a guess based upon guessed electronic structure).

                                    Bohrium: description  

                                    Bohrium is a synthetic element that is not present in the environment at all. The German discoverers at GSI proposed the name Nielsbohrium (symbol Ns) after Niels Bohr. IUPAC are happy to name an element after Bohr but suggest bohrium (Bh) on the grounds that the first name of a person does not appear in the names of any other element named after a person. This seems to have been accepted by all concerned.

                                    网络斗地主下载The interested reader should consult the on-line version of for a fascinating insight into research on "super-heavy" atoms.

                                    Bohrium: isolation

                                    Isolation: only a few atoms of element 107, bohrium, have ever been made. The first atoms were made through a nuclear reaction involving fusion of an isotope of lead, 209Pb, with one of chromium, 54Cr.

                                    209Pb + 54Cr → 262Bh + 1n

                                    网络斗地主下载Isolation of an observable quantity of bohrium has never been achieved, and may well never be. This is because bohrium decays very rapidly through the emission of α-particles.

                                    More recently, other isotopes have been made at the Paul Scherrer Institute (PSI) in Switzerland.

                                    249Bk + 22Ne → 266Bh + 51n

                                    249Bk + 22Ne → 267Bh + 41n

                                    In this work, it appears the scientists concerned feel bohrium forms the oxychloride BhClO3.
