Beispiele für die Verwendung von ROENTGENIUM in einem Satz

• The European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and the European Space Agency's European Space Operations Centre (ESA ESOC) are located in Darmstadt, as well as GSI Centre for Heavy Ion Research, where several chemical elements such as bohrium (1981), meitnerium (1982), hassium (1984), darmstadtium (1994), roentgenium (1994), and copernicium (1996) were discovered.
• Roentgenium was first created in 1994 by the GSI Helmholtz Centre for Heavy Ion Research near Darmstadt, Germany.
• In chemistry, Group 11 of the Periodic Table of the Elements (IUPAC numbering) consists of the three coinage metals copper, silver, and gold known from antiquity, and roentgenium, a recently synthesized superheavy element.
• Peter Armbruster (25 July 1931 – 26 June 2024) was a German physicist at the Gesellschaft für Schwerionenforschung (GSI) facility in Darmstadt, Germany, and is credited with co-discovering elements 107 (bohrium), 108 (hassium), 109 (meitnerium), 110 (darmstadtium), 111 (roentgenium), and 112 (copernicium) with research partner Gottfried Münzenberg.
• He was the driving force in the discovery of the cold heavy ion fusion and the discovery of the elements bohrium (Z = 107), hassium (Z = 108), meitnerium (Z = 109), darmstadtium (Z = 110), roentgenium (Z = 111), and copernicium (Z = 112).
• He is known for the co-discoveries of elements 110, 111, and 112 (darmstadtium, roentgenium and copernicium, respectively).
• Sigurd Hofmann, physicist and discoverer of the chemical elements darmstadtium (Ds, atomic number 110), roentgenium (Rg, 111) and copernicium (Cn, 112).
• Parent roentgenium nuclei can be themselves decay products of nihonium, flerovium, moscovium, livermorium, or tennessine.
• Darmstadtium may also have been produced in the electron capture decay of roentgenium nuclei which are themselves daughters of nihonium and moscovium.
• From the mid-1970s to the mid-1990s, the partnership of JINR, directed by Oganessian, and the GSI Helmholtz Centre for Heavy Ion Research in Germany, resulted in the discovery of six chemical elements (107 to 112): bohrium, meitnerium, hassium, darmstadtium, roentgenium, and copernicium.
• Named in his honor (in addition to the official name of x-ray radiation, "Roentgen rays"; the "roentgenogram" image, commonly called "an x-ray"; and the roentgen as the unit of measure of exposure to radiation) is the element Roentgenium, atomic number 111.
• A later attempt at characterization of the progenitor in 1975 by Edward Anders, a professor of chemistry at the University of Chicago, and colleague John Larimer suggested a heat of vaporization of 54 kJ/mol and a boiling point of 2500K for the element and, based on estimated accretion temperatures, they also proposed elements 111 and 115 (today named roentgenium and moscovium) as the most likely candidates assuming the element condensed in pure form.
