© copyright 2003-2020 Study.com. Ytterbium is a chemical element with the symbol Yb and atomic number 70. study [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. Beyond x-ray machines, ytterbium has a few other commercial uses. The main mining areas are China, the United States, Brazil, India, Sri Lanka, and Australia. [9], Ytterbium was discovered by the Swiss chemist Jean Charles Galissard de Marignac in the year 1878. [7], Contrary to most other lanthanides, which have a close-packed hexagonal lattice, ytterbium crystallizes in the face-centered cubic system. A relatively pure sample of the metal was not obtained until 1953. The clocks would be accurate within a second for a period comparable to the age of the universe. The model with one single ytterbium ion caught in an ion trap is highly accurate. and career path that can help you find the school that's right for you. The metal is a fire and explosion hazard.

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). Ytterbium has few uses. I found some stuff about that but its all like complicated stuff that i can't understand. Ytterbium has the chemical symbol Yb and is found in the lanthanoid group, generally shown at the bottom of the periodic table. Ytterbium. Its atomic mass is 88.906 and is sometimes mistook for ytterbium. In aqueous solution, like compounds of other late lanthanides, soluble ytterbium compounds form complexes with nine water molecules. [49] The optimization of the ytterbium-doped glass itself through host glass modification of various dopants also plays a large part in reducing the background loss of the glass, improvements in slope efficiency of the fiber, and improved photodarkening performance, all of which contribute to increased power levels in 1 µm systems. [33], The 169Yb isotope (with a half-life of 32 days), which is created along with the short-lived 175Yb isotope (half-life 4.2 days) by neutron activation during the irradiation of ytterbium in nuclear reactors, has been used as a radiation source in portable X-ray machines. Some ytterbium isotopes generate gamma rays, which can be used to create a radiographic image of an object without the use of electricity. It is the last of four elements named after the town of Ytterby, Sweden. Ytterbium chloride is used as a filling for teeth and as an x-ray contrast agent. credit-by-exam regardless of age or education level. {{courseNav.course.topics.length}} chapters | Because of its closed-shell electron configurati… Stimulated emission generated in the fiber passes through the inner core, which often is singlemode. [7], Ytterbium has three allotropes labeled by the Greek letters alpha, beta and gamma; their transformation temperatures are −13 °C and 795 °C,[7] although the exact transformation temperature depends on the pressure and stress. [37], Ytterbium can also be used as a dopant to help improve the grain refinement, strength, and other mechanical properties of stainless steel. In 1878, the Swiss chemist Jean Charles Galissard de Marignac separated from the rare earth "erbia" another independent component, which he called "ytterbia", for Ytterby, the village in Sweden near where he found the new component of erbium. F3Yb It is also used as industrial catalyst as the other catalysts are too toxic and polluting. It is used in improving the grain refinement, strength. 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.
