One of ytterbium's isotopes is being considered as a radiation source for portable X-ray machines. Group Pension. NIST physicists reported in the August 22, 2013 issue of Science Express that the ytterbium clocks' ticks are stable to within less than two parts in 1 quintillion (1 followed by 18 zeros), roughly 10 times better than the previous best published results for other atomic clocks. The charged ion 171Yb+ is used in trapped-ion qubits in quantum computing. The main deposits of ytterbium are found in China, United States, Brazil, India, Sri Lanka and Australia.  After Urbain's names were recognized, neoytterbium was reverted to ytterbium. Reserves of ytterbium are estimated as one million tonnes. It can be alloyed with stainless steel to improve some of its mechanical properties and used as a doping agent in fiber optic cable where it can be used as an amplifier. Ytterbium is present along with several rare minerals. At present, ytterbium is mainly used as a dopant of stainless steel or active laser media, and less often as a gamma ray source. For example, ytterbium(III) chloride (YbCl3) is a Lewis acid and can be used as a catalyst in the Aldol and Diels–Alder reactions. Group Number: 3. Atomic Number 70 is belong to element of Ytterbium.. Chemical symbol for Ytterbium is Yb. Atomic number: 70: Group numbers: 3: Period: 6: Electronic configuration: [Xe] 4f 14 6s 2: Formal oxidation number: +2 +3: Electronegativities:-Atomic radius / pm: 194: Relative atomic mass: 173.054(5) The solution is then applied to a resin, which different lanthanides bind in different matters. Ytterbium dissolves slowly in water, but quickly in acids, liberating hydrogen gas. Ytterbium is normally difficult to separate from other rare earths, but ion-exchange and solvent extraction techniques developed in the mid- to late 20th century have simplified separation. Ytterbium is soft, malleable and quite ductile element with an appearance of bright silvery luster.  The Commission on Atomic Mass, consisting of Frank Wigglesworth Clarke, Wilhelm Ostwald, and Georges Urbain, which was then responsible for the attribution of new element names, settled the dispute in 1909 by granting priority to Urbain and adopting his names as official ones, based on the fact that the separation of lutetium from Marignac's ytterbium was first described by Urbain. Welcome to customer support. However, like the other lanthanides, its most common oxidation state is +3, as in its oxide, halides, and other compounds. In 1907, the French chemist Georges Urbain separated Marignac's ytterbia into two components: neoytterbia and lutecia. Technical data for Ytterbium. Yttrium is a chemical element with the symbol Y and atomic number 39. 89Y is the only stable isotope, and the only isotope found in … Ytterbium is a silvery-white chemical element that belongs to the group of lanthanides. He suspected that ytterbia was a compound of a new element that he called "ytterbium" (in total, four elements were named after the village, the others being yttrium, terbium, and erbium). Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals, and is never found in nature as a free element. Atomic Weight: 174.9668. Power levels have increased from the 1 kW regimes due to the advancements in components as well as the Yb-doped fibers. all factors of the fiber must be considered. Experiments show that radiographs taken with a 169Yb source are roughly equivalent to those taken with X-rays having energies between 250 and 350 keV. , Ytterbium metal tarnishes slowly in air, taking on a golden or brown hue. Much progress has been made in the power scaling lasers and amplifiers produced with ytterbium (Yb) doped optical fibers. Its melting and boiling points are also significantly lower than those of thulium and lutetium. This is then dissolved using complexing agents, and due to the different types of bonding exhibited by the different lanthanides, it is possible to isolate the compounds. The metal is purified by sublimation and collected over a condensed plate. Ytterbium has a density of 6.973 g/cm3, which is significantly lower than those of the neighboring lanthanides, thulium (9.32 g/cm3) and lutetium (9.841 g/cm3). In 1907, the new earth "lutecia" was separated from ytterbia, from which the element "lutecium" (now lutetium) was extracted by Georges Urbain, Carl Auer von Welsbach, and Charles James. The primary decay products of ytterbium isotopes lighter than 174Yb are thulium isotopes, and the primary decay products of ytterbium isotopes with heavier than 174Yb are lutetium isotopes. Like europium, samarium, and thulium, the trihalides of ytterbium can be reduced to the dihalides by hydrogen, zinc dust, or by the addition of metallic ytterbium.
