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. Compounds of ytterbium are rare and have not yet been well characterized. [52], Currently, ytterbium is being investigated as a possible replacement for magnesium in high density pyrotechnic payloads for kinematic infrared decoy flares. Yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. 6s2 and the term symbol of ytterbium is 1S0. Melting Point: 1936 K (1663°C or 3025°F) Boiling Point: 3675 K (3402°C or 6156°F) Density: 9.84 grams per cubic centimeter. What's in a name? This property is used in stress gauges to monitor ground deformations from earthquakes and explosions. At high concentrations, the ytterbium-doped materials show photodarkening[45] Ytterbium is a soft, malleable and rather ductile element that exhibits a bright silvery luster.A rare earth, the element is easily attacked and dissolved by mineral acids, slowly reacts with water, and oxidizes in air.The oxide forms a protective layer on the surface. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. 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. [16], Ytterbium is often the most common substitute in yttrium minerals. A report of native ytterbium from the Moon's regolith is known. Yttrium is a silvery white, moderately soft, ductile metal. Phase at Room Temperature: Solid. 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). Atomic Number. The mineral gadolinite ((Ce, La, Nd, Y)2FeBe2Si2O10), discovered in a quarry near the town of Ytterby, Sweden, has been the source of a great number of rare earth elements. 4f14. Name. Visible light waves oscillate faster than microwaves, and therefore optical clocks can be more precise than caesium atomic clocks. Due to his original belief of the composition of ytterbia, Marignac is credited with the discovery of ytterbium. Ytterbium: 7440-64-4: Hangzhou Dayangchem Co., Ltd. Inquiry: YTTERBIUM: 7440-64-4: Hebei yanxi chemical co.,LTD. Ytterbium metal behaves similarly to europium metal and the alkaline earth metals, dissolving in ammonia to form blue electride salts. [14][15], The isotopes of ytterbium range in atomic weight from 147.9674 atomic mass unit (u) for 148Yb to 180.9562 u for 181Yb. The world production of ytterbium is only about 50 tonnes per year, reflecting that it has few commercial applications. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. [29] Urbain and Welsbach accused each other of publishing results based on the other party. [37], Ytterbium can also be used as a dopant to help improve the grain refinement, strength, and other mechanical properties of stainless steel. The charged ion 171Yb+ is used in trapped-ion qubits in quantum computing. We publish and operate an extensive portfolio of digital and print products featuring comprehensive in-depth content from the… Neoytterbia later became known as the element ytterbium, and lutecia became known as the element lutetium. As a result, the process is somewhat long. Group Name: Lanthanide. Like X-rays, the gamma rays emitted by the source pass through soft tissues of the body, but are blocked by bones and other dense materials. Technical data for Ytterbium. The model with one single ytterbium ion caught in an ion trap is highly accurate. Ytterbium abundance in earth crust is about 3 mg/kg. The ytterbium concentration is low because it is found only among many other rare earth elements; moreover, it is among the least abundant. Other chemists produced and experimented with ytterbium in an attempt to determine some of it's properties. [11] However, the alpha allotrope is diamagnetic. The melting point of ytterbium is 1,097 degrees Kelvin … The main deposits of ytterbium are found in China, United States, Brazil, India, Sri Lanka and Australia. The metal is extracted from the solution as oxalate and converted to oxide by heating. After some discussion, Marignac's name "ytterbium" was retained. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3. All of the remaining radioactive isotopes have half-lives that are less than two hours, and most of these have half-lives under 20 minutes. Atomic weight of Ytterbium is 173.045 u or g/mol. This behavior is unusual for lanthanides, which almost exclusively form compounds with an oxidation state of +3. Ytterbium (symbol Yb, atomic number 70) is a naturally formed chemical element known to science since the 1840s. Melting Point: 1092 K (819°C or 1506°F) Boiling Point: 1469 K (1196°C or 2185°F) Density: 6.90 grams per cubic centimeter. It is the fourteenth and penultimate element in the lanthanide series, which is the basis of the relative stability of its +2 oxidation state. Fabrication of Low NA, Large Mode Area fibers enable achievement of near perfect beam qualities (M2<1.1) at power levels of 1.5 kW to greater than 2 kW at ~1064 nm in a broadband configuration. [18][19], Ytterbium is separated from other rare earths either by ion exchange or by reduction with sodium amalgam. While examining samples of gadolinite, Marignac found a new component in the earth then known as erbia, and he named it ytterbia, for Ytterby, the Swedish village near where he found the new component of erbium. [9], Ytterbium is quite electropositive, and it reacts slowly with cold water and quite quickly with hot water to form ytterbium(III) hydroxide:[13], Ytterbium reacts with all the halogens:[13], The ytterbium(III) ion absorbs light in the near infrared range of wavelengths, but not in visible light, so ytterbia, Yb2O3, is white in color and the salts of ytterbium are also colorless. Ytterbium is pronounced as i-TUR-bee-em.

While some scientists believed that these inconsistent results were caused by poor procedures or faulty equipment, Georges Urbain, a French chemist, believed that ytterbium wasn't an element at all, but a mixture of two elements. It is common substitute to yttrium minerals. In the latter method, a buffered acidic solution of trivalent rare earths is treated with molten sodium-mercury alloy, which reduces and dissolves Yb3+. Its electrical resistivity increases ten times upon compression to 39,000 atmospheres (3.9 GPa), but then drops to about 10% of its room-temperature resistivity at about 40,000 atm (4.0 GPa). Unfortunately, different scientists obtained different results from the same experiments. A pair of experimental atomic clocks based on ytterbium atoms at the National Institute of Standards and Technology has set a record for stability. Group Number: 3. Ytterbium Ytterbium is a chemical element with symbol Yb and atomic number 70. 8773427775 Monday - Friday 8:30 AM - 4:30 PM . One of ytterbium's isotopes is being considered as a radiation source for portable X-ray machines. This effect may be related with not only overheating, but also with conditions of charge compensation at high concentrations of ytterbium ions.[47]. By Tribune News Service (glass fibers) or even a switch to broadband emission[46] (crystals and ceramics) instead of efficient laser action. Ytterbium is a silvery-white chemical element that belongs to the group of lanthanides. In 1878 Jean Charles Galissard de Marignac, a Swiss chemist, discovered that erbia was itself consisted of two components. Name: Ytterbium Symbol: Yb Atomic Number: 70 Atomic Mass: 173.04 amu Melting Point: 824.0 °C (1097.15 K, 1515.2 °F) Boiling Point: 1466.0 °C (1739.15 K, 2670.8 °F) Number of Protons/Electrons: 70 Number of Neutrons: 103 Classification: Rare Earth Crystal Structure: Cubic Density @ 293 K: 6.98 g/cm 3 Color: Silvery Atomic Structure The metal readily reacts with diluted The metal is purified by sublimation and collected over a condensed plate. Symbol. First, minerals such as monazite or xenotime are dissolved into various acids, such as sulfuric acid. [9] The +2 oxidation state occurs only in solid compounds and reacts in some ways similarly to the alkaline earth metal compounds; for example, ytterbium(II) oxide (YbO) shows the same structure as calcium oxide (CaO). Equitable Benefit Payment Services Group, … Marignac suspected that ytterbia was a compound of a new element that he called "ytterbium".[10][24][26][27][28]. Here you will find forms, contact information, answers to common questions and more. Ytterbium lasers are highly efficient, have long lifetimes and can generate short pulses; ytterbium can also easily be incorporated into the material used to make the laser. 9h ago. Atomic Number: 71. [30][31][32] 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.
