What is the most common isotope of ytterbium?
Naturally occurring ytterbium (70Yb) is composed of 7 stable isotopes, 168Yb–176Yb, with 174Yb being the most abundant (31.83% natural abundance).
What family is ytterbium in?
lanthanide family
Ytterbium belongs to the lanthanide family. The lanthanides make up Row 6 of the periodic table. The periodic table is a chart that shows how the chemical elements are related to each other. The lanthanides are also known as the rare earth elements.
What is ytterbium in the periodic table?
ytterbium (Yb), chemical element, a rare-earth metal of the lanthanide series of the periodic table.
Is ytterbium paramagnetic or diamagnetic?
In contrast with the other rare-earth metals, which usually have antiferromagnetic and/or ferromagnetic properties at low temperatures, ytterbium is paramagnetic at temperatures above 1.0 kelvin. However, the alpha allotrope is diamagnetic.
What is ytterbium found in?
1878
Ytterbium/Discovered
What is ytterbium important?
Uses of Ytterbium It is used as a doping agent to improve the strength, grain refinement and mechanical properties of stainless steel. It also acts as an industrial catalyst. Few alloys of Ytterbium are used in dentistry.
How common is ytterbium?
Ytterbium is the 44th most abundant element in the Earth’s crust. It is one of the more common rare earths, present at about 2.7 to 8 parts per million in the crust. It is common in the mineral monazite. 7 natural isotopes of ytterbium occur, plus at least 27 radioactive isotopes have been observed.
Where is ytterbium commonly found?
Ytterbium is found with other rare-earth elements in several rare minerals. It is most often recovered commercially from monazite sand (0.03% ytterbium). The element is also found in euxenite and xenotime. The main mining areas are China, the United States, Brazil, India, Sri Lanka, and Australia.
What are the physical properties of the element ytterbium?
Daane, Dennison, and Spedding prepared a much purer from in 1953 from which the chemical and physical properties of the element could be determined. Ytterbium has a bright silvery luster, is soft, malleable, and quite ductile. Even though the element is fairly stable, it should be kept in closed containers to protect it from air and moisture.
What can you do with unstable isotope ytterbium?
Seven other unstable isotopes are known. Ytterbium has few uses. 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. One of ytterbium’s isotopes is being considered as a radiation source for portable X-ray machines.
How is ytterbium extracted from rare earth elements?
It can be extracted by ion exchange and solvent extraction. Ytterbium was isolated in 1878 by Jean Charles Galissard de Marignac at the University of Geneva. The story began with yttrium, discovered in 1794, which was contaminated with other rare-earth elements (aka lanthanoids).
What is the atomic number of the element YB?
Ytterbium is a chemical element with symbol Yb and atomic number 70. Classified as a lanthanide, Ytterbium is a solid at room temperature. NAWDYIZEMPQZHO-UHFFFAOYSA-N
