It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3. In addition, ten radioactive isotopes are also known; these isotopes are unstable and break down into other isotopes giving out radiation in the process.
Its discovery can be traced back to the oxide yttria. The percentage of an element produced in the top producing country. Ytterbium is element number 70 with an element symbol Yb. Now next week, we've got an explosive element and I'll give one you guess as to who it's named after. Copyright of and ownership in the Images reside with Murray Robertson. Chemistry in its element is brought to you by the Royal Society of Chemistry and produced by. Ytterbium atoms have 70 electrons and the shell structure is 2.8.18.32.8.2.

The temperature at which the liquid–gas phase change occurs. A percentile rank for the political stability of the top producing country, derived from World Bank governance indicators. When the bomb exploded on November the first, 1952, it produced an explosion with the power of over 10 million tonnes of TNT - five hundred times the destructive power of the Nagasaki explosion. The atomic mass is the mass of an atom. Pornographic, defamatory, libellous, scandalous, fraudulent, immoral, infringing or otherwise unlawful use of the Images is, of course, prohibited. Ytterbium is found in minerals such as yttria, monazite, gadolinite and xenotime. There among the ash and charred remains of coral were found a couple of hundred atoms of element 99, later to be called einsteinium.
When yttria was first identified, nobody realised that it was contaminated with traces of other rare earth metals. Copyright © 1996-2012 Yinon Bentor.

The higher the value, the larger risk there is to supply. Additional Notes: Ytterbium Menu. A measure of how difficult it is to compress a substance. These values were determined using several different methods. (1), (2)In 1907, in Paris, George Urbain separated ytterbia into two constituents. Named after Ytterby, a village in Sweden. Ytterbium can also exist in the +2 valence state; its compounds are powerful reducing agents and it is capable of reducing water to hydrogen gas.
A vertical column in the periodic table. Some elements exist in several different structural forms, called allotropes. Uncombined elements have an oxidation state of 0.
Date of Discovery Additionally, ytterbium compounds are often more potent catalysts than their lanthanide counterparts. All Rights Reserved. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. The isotope Yb-174 has the potential to keep time more accurately than the current gold standard, which is a caesium fountain clock that is accurate to within a second every 100 million years. The ground state electronic configuration of neutral ytterbium is [Xe].4f 14.6s 2 and the term symbol of ytterbium is 1 S 0.. Ytterbium: description Your user agent does not support the HTML5 Audio element. Relative atomic mass
The higher the value, the larger risk there is to supply. Alkaline Earth Metals Annual world wide production is around 50 tons. Isotopes Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. Name The only ytterbium compound of historical commercial use is ytterbium oxide (Yb2O3); this is used to make alloys and special types of glass and ceramics. Atomic Mass The images may not be posted on any website, shared in any disc library, image storage mechanism, network system or similar arrangement. Ytterbium is also used in some laser systems and ytterbium fibre laser amplifiers are found in commercial and industrial applications where they are used in marking and engraving. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. Density is the mass of a substance that would fill 1 cm. Yttrium is a chemical element with atomic number 39 which means there are 39 protons in its nucleus. Ytterbium was isolated in 1878 by Jean Charles Galissard de Marignac who was a Swiss chemist working at the University of Geneva at the time.

The naturally occurring ytterbium is a mixture of seven stable isotopes with mass numbers 168, 170 to 174 and 176. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Isotope abundances of ytterbium. Ytterbium is an element of the periodic table with an atomic number of 70, discovered by Jean de Marignac in the year 1878. Ytterbium was isolated in 1878 by Jean Charles Galissard de Marignac at the University of Geneva. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Ytterbium, which was first obtained in a pure state just some 50 years ago, only two calibrated measurements of its isotopic composition have been ever made.

Ytterbium, 70 Yb Ytterbium; Pronunciation / ɪ ˈ t ɜːr b i ə m / (ih-TUR-bee-əm) Appearance: sillery white: Standard atomic weight A r, std (Yb): 173.045(10) Mass number: Yb: Ytterbium in the periodic cairt Today, ytterbium is primarily obtained through an ion exchange process from monazite sand ((Ce, La, Th, Nd, Y)PO 4), a material rich in rare earth elements. The percentage of a commodity which is recycled. With an atomic number of 70, and an atomic mass of 173.04 g/mol, Ytterbium also has common oxidation states of 2+ and 3+. Where more than one isotope exists, the value given is the abundance weighted average. Seven naturally occurring isotopes of ytterbium are known.
