6 Μαρ 2017 · Bohrium is a transition metal with atomic number 107 and element symbol Bh. This man-made element is radioactive and toxic. Here is a collection of interesting bohrium element facts, including its properties, sources, history, and uses.
Bohrium does not occur naturally in the Earth’s crust. Bohrium was first synthesized by German scientists at the GSI Center for Heavy Ion Research in Darmstadt, Germany in 1981 using the nuclear reaction 209Bi (54Cr, n) 262Bh. The element is named for Niels Bohr (Figure 4.107.1), the Nobel Prize winning physicist [646, 647].
Discover everything you need to know about Bohrium (Element 107), a synthetic, superheavy element. Learn about its discovery, physical and chemical properties, sources, and why it's important in the realm of nuclear physics.
Bohrium is a synthetically made radioactive element. Only a few atoms have ever been produced. Bohrium decays very rapidly through the emission of α-particles. Uses of Bohrium. Bohrium’s only use is in research. Abundance and Isotopes. Abundance earth’s crust: nil. Abundance solar system: parts per billion by weight, parts per trillion by moles.
Bohrium is a synthetic element so its existence was discovered by two groups. First time in 1976 a team led by Yuri Oganessian (Russia), bombarded bismuth-209 and with chromium-54 and produced an isotope of a novel element that has an atomic mass of 261 and a half-life of around 2 millisecond.
BOHRIUM 107 NAME COLD FUSION SHORT-LIVED The first element made by colliding two nuclei in a low excitation energy cold fusion reaction was bohrium. Bohrium’s longest-lived isotope has a half-life of about a minute. It has no uses outside research. #107 [270] Ci © 2019 Andy Brunning/Royal Society of Chemistry #IYPT2019 Bohrium was created
