Examples

“Gold crystallises in the face-centred cubic (fcc) habit, its lattice constant being fractionally smaller than that of silver (Tables 2.1 and 2.2.); in compounds and complexes, Auᴵ is smaller than Agᴵ. This is in consequence of the relativistic contraction of the 6s level, and it is expected that it will be even greater with the 7s level; indeed the size of the next element of Group 11 (röntgenium) has been calculated to be no larger than that of copper.”

“Copper (^(63.546)₂₉Cu), OS: +2, +1, 0; IE: 745.3, 1957.3, 3577.6 kJ mol⁻¹.[…]Röntgenium (^([272])₁₁₁Rg) / No data are available.”

“One example is SHIPTRAP, its name originating from the SHIP velocity filter that was used to discover six new elements: ²⁶⁴₁₀₇Bh (Bohrium, 1981), ²⁶⁹₁₀₈Hs (Hassium, 1984), ²⁶⁸₁₀₉Mt (Meitnerium, 1982), ²⁷¹₁₁₀Ds (Darmstadtium, 1994), ²⁷²₁₁₁Rg (Röntgenium, 1994), and ²⁷⁷₁₁₂Uub (Ununbium, 1996).”

“Possibility of Rg to form simple monovalent compounds and predominance of relativistic effects on its electron shells made this element an attractive object of theoretical investigations.”

“p. 237, “spelling disagreement”: Aside from differences between languages, other spelling discrepancies within a language occur with cesium, which the British tend to spell “caesium,” and sulfur, which many people still spell “sulphur.” You could make a case that element 110 should be spelled mendeleevium, not mendelevium, and that element 111 should be spelled röntgenium, not roentgenium.”

“The reader who has encountered any of the entries for: curium, einsteinium, fermium, mendelevium, nobelium, lawrencium, rutherfordium, seaborgium, bohrium, meitnerium and röntgenium, will have realised that it is a mark of the highest distinction in science to have a chemical element named after one.”

“I research Wilhelm Conrad Röntgen. He discovered X-rays in 1895 and first tested them on his wife’s hand. She exclaimed, “I can see my death.” He received a Nobel Prize in Physics and Röntgenium was named in his honor.”

“After his discovery the University of Würzburg awarded an honorary Doctor of Medicine degree to Röntgen. The element number 111 was named Röntgenium (Rg) in his honor, in November 2004.”

“In tribute to Röntgen’s contributions to modern physics the element with the atomic number 111 was named röntgenium (Rg).”

“TABLE 1.4 People after whom elements have been named. /[…]/ [“Name”] Wilhelm Röntgen (1845–1923) [“Brief biography”] German physicist; discoverer of X-rays; winner of the inaugural Nobel Prize in physics in 1901 [“Element named”] röntgenium, Rg (element 111)”

“Roentgenium (Rg, element 111), after the German physicist Wilhelm Conrad Röntgen (1845–1923). One should note that an etymologically correct eponym would have been röntgenium.”

“The individual names of these elements, are: Rutherfordium (Rf, Z = 104), dubnium (Db, Z = 105), seaborgium (Sg, Z = 106), bohrium (Bh, Z = 107), hassium (Hs, Z = 108), meitnerium (Mt, Z = 109), darmstadtium (Ds, Z = 110), röntgenium (Rg, Z = 111), copernicium (Cn, Z = 112), nihonium (Nh, Z = 113), flerovium (Fl, Z = 114), moscovium (Mc, Z = 115), livermorium (Lv, Z = 116), tennessine (Ts, Z = 117), oganesson (Og, Z = 118).”
