Some ytterbium alloys have been used in dentistry. It is also the 70th element on the periodic table. Atomic Mass Average: 173.04 It is attacked by the strong acids and reacts slowly with cold water and air. Ytterbium has a bright silvery luster, is soft, malleable, and quite ductile. Ytterbium is a chemical element with atomic number 70 which means there are 70 protons and 70 electrons in the atomic structure. Its metal could be used to help improve the grain refinement, strength, and other mechanical properties of stainless steel. It reacts … One ytterbium isotope has been used as a radiation source substitute for a portable X-ray machine when electricity was not available. Ytterbium has no biological role, but it has been noted that its salts stimulate metabolism. Ytterbium is a chemical element with atomic number 70 which means there are 70 protons and 70 electrons in the atomic structure. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. Ytterbium poses no threat to plants and animals and its salts are being introduced into the chemical industry as catalysts in place of ones that are regarded as toxic and polluting. Chemical reactions for ytterbium. It is used in metallurgical and chemical experiments. Ytterbium is a soft, malleable and rather ductile element that exhibits a bright silvery luster. It is a white silvery, soft, ductile and rare earth metal. The element was first prepared by Klemm and bonner in 1937 by reducing ytterbium trichloride with potassium. It is a rare earth element, and it is readily dissolved by the strong mineral acids. Home. Ytterbium has been used in lasers and as a portable x-ray source. Chemical Properties. Even though the element is fairly stable, it should be kept in closed containers to protect it from air and moisture. Reaction of ytterbium with air. Ytterbium burns in powder mixture with hexachloroethane and produce luminous emerald green flame. Ytterbium, a silvery white metal is electropositive which reacts with water to form ytterbium hydroxide. Usually, elements will have ferromagnetic and antiferromagnetic properties at low temperatures but it is paramagnetic at a temperature of 0.1 Kelvin. It reacts slowly with cold water and it oxidizes slowly in air. Heatscape representing the molar volume of the periodic table elements. It reacts with all halogens and form dihalides and trihalides. Credit for discovering ytterbium is shared between Jean-Charles Gallisard de Marignac, Lars Fredrik Nilson, and Georges Urbain, who identified the element over a period of several years, starting in 1787. Ytterbium is sometimes associated with yttrium or other related elements and is used in certain steels. Characteristics Physical properties. It has the atomic symbol Yb, atomic number 70, and atomic weight 173. Usually, elements will have ferromagnetic and antiferromagnetic properties at low temperatures but it is paramagnetic at a temperature of 0.1 Kelvin. Few alloys of Ytterbium are used in dentistry. Ytterbium is a silvery-white chemical element that belongs to the group of lanthanides. Nowadays, this is element is used in the making of memory devices and tunable lasers. ... 1.8 Other Chemical Properties. The chemical properties of ytterbium nanoparticles are outlined in the following table. It is a soft, malleable silvery metal that will tarnish slightly when stored in air and therefore should be stored in vacuum or in an inert Phone: +971 4 429 5853 e-mail: info@lenntech.com, Copyright © 1998-2020 Lenntech B.V. All rights reserved, Plant Inspection & Process Optimalisation, Separation and Concentration Purification Request. Ytterbium is a soft, malleable and ductile chemical element that displays a bright silvery luster when pure. The price of 99.9 % pure ytterbium ingot is 188.50 € for 25 g. Ytterbium nanoparticles have interesting magnetic and optical properties, with applications in imaging and biomedical science. An element of the rare earth family of metals. Ytterbium is found in monazite sand as well as the ores euxenite and xenotime. The chemical symbol for ytterbium is Yb. Ytterbium is a silver metal with an atomic number of 70, meaning there are 70 protons in its nucleus. Physical properties of Ytterbium differ widely when compared to other elements. Yttrium and Ytterbium chemical properties are one of the most important characteristics.
