	Element 107 Bohrium Chemistry
		Crucial to the research was the use of an isotope of bohrium with a relatively long half-life of about 15 seconds, detected earlier this year by researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley.
		Bohrium 267 was unambiguously identified by the pattern of its alpha decay, first to dubnium 263, then to lawrencium 259, and subsequently to mendelevium 255.
		The oxychloride of bohrium was shown to be volatile at 180 C, similar to its lighter homologues in group VII of the periodic table, such as rhenium and technetium.

	Chemistry : Periodic Table : bohrium : key information
		Bohrium is a synthetic element that is not present in the environment at all.
		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 is because bohrium decays very rapidly through the emission of α-particles.

	bohrium - Encyclopedia.com
		The Germans suggested the name nielsbohrium, which the Soviets had suggested be given to element 105 (dubnium), to honor the Danish physicist Niels Bohr.
		While this conforms to the names of other elements honoring individuals, where only the surname is taken, it was opposed by many who were concerned that it could be confused with boron, the name for element 5.
		In 1997, however, the name bohrium for element 107 was recognized internationally.

	Bohrium Information
		Bohrium (Eka-Rhenium) is a chemical element in the periodic table that has the symbol Bh and atomic number 107.
		There was an element naming controversy as to what the elements from 101 to 109 were to be called; thus IUPAC adopted unnilseptium (symbol Uns) as a temporary, systematic element name for this element.
		Despite this, the name bohrium for element 107 was recognized internationally in 1997.

	It's Elemental - The Element Bohrium
		First produced in 1976 by scientists working at the Joint Institute for Nuclear Research in Dubna, Russia, and later confirmed in 1981 by Peter Armbruster, Gottfried Münzenber and their team working at the Gesellschaft für Schwerionenforschung in Darmstadt, Germany, bohrium was produced by bombarding a target of bismuth-209 with ions of chromium-54.
		Bohrium's most stable isotope, bohrium-272, has a half-life of about 9.8 seconds.
		Since only a few atoms of bohrium have ever been made, there are currently no uses for bohrium outside of basic scientific research.

		Bohrium is expected to have chemical properties similar to rhenium.
		This element was synthesized and unambiguously identified in 1981 using the Universal Linear Accelerator (UNILAC) at the Gesellschaft für Schwerionenforschung (G.S.I.) in Darmstadt, Germany.
		One isotope of bohrium appears to have a relatively long life of 15 seconds.

		Bohrium is a synthetic, metallic element that is not present in our natural environment.
		Scientists in Russia had reported producing bohrium in 1976, and this work was verified by workers later in Darmstadt, Germany, when it was discovered by Peter Armbruster, Gottfried Munzenberg and their coworkers at GSI.
		The first bohrium atoms were made when a lead isotope was fused with a chromium isotope in a nuclear reaction.

	CERN Courier - Bohrium finds a place in the - IOP Publishing - article
		The bohrium experiment aimed to close the information gap, and investigate whether the element belongs to Group VII (which includes the elements rhenium and technetium).
		Confirmation of the presence of bohrium, with single-atom sensitivity, was achieved using a rotating wheel multidetector analyser (ROMA).
		Using a total of just six detected atoms, it was shown that bohrium indeed forms volatile oxychlorides at a temperature of 180 ºC, within the expected range of 200 ºC for Group VII elements.

	The Element Bohrium
		Bohrium was discovered by Peter Armbruster and Gottfried Munzenberg at Darmstadt, Germany in 1981.
		It was synthesized in 1976 by a Soviet team led by Y. Oganessian at the Institute for Nuclear Research at Dubna in Russia.

	Bohrium
		Subsequently an international collaboration produced Bohrium and determined its volatility using a cyclotron at the Paul Scherrer Institute (PSI) in Bern, Switzerland.
		Four molecules of a compound containing Bohrium 267 were volatile at 180°C, passed through the chromatography column, deposited on a rotating carrier, and then were identified by their radiation.
		The Bohrium 267 was unambiguously identified by alpha decay (with a half life of 15 seconds) to Dubnium 263, next to Lawrencium 259, and then to Mendelevium 255.

		Name: Bohrium is named after Danish physicist Niels Bohr, who proposed the modern concept of the atom; hassium comes from the Latin Hassia, Germany.
		All bohrium isotopes were identified by time correlations to known isotopes of lighter elements using single-event detection.
		At the Paul Scherrer Institute in Switzerland, it was shown that bohrium is a group 7 element, the big brother of rhenium, technetium, and manganese.

	* Dusted Features [ Strength in (Atomic) Numbers - A preview of Table of the Elements Festival No. 4 — Bohrium ] *
		Bohrium, element 107 in the periodic table, is one of a largely speculative nature.
		Created by German scientists in 1981, Bohrium exists in a highly unstable state; very few atoms of the synthesized element have ever been created, and, therefore, concrete observations of the nature of Bohrium are extremely limited.
		Perhaps label head Jeff Hunt was inspired by the mysterious nature of Bohrium, or maybe the choice was made on more phonetically aesthetic terms, but, whatever its genesis, the elemental name of this year’s festival is one that’s rather contradictory, as Labor Day weekend at the Eyedrum in Atlanta figures to be anything but Bohr-ing.
