The number written to the right of the element's name is the mass number. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. The number of atoms of the element per 1 million atoms of the Earth’s crust. Isotopes Relative atomic mass Its discovery can be traced back to the oxide yttria. They undergo deformation but depends on pressure and stress at temperature about -13OC and 795OC. In 2015, the standard atomic weight of ytterbium was revised to 173.045(10). This page was created by Yinon Bentor. Ytterbium is element number 70 with an element symbol Yb. 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. Additional Notes: Ytterbium Menu. Uncombined elements have an oxidation state of 0. A percentile rank for the political stability of the top producing country, derived from World Bank governance indicators. Help Alkali Metals Ytterbium is named after Ytterby, Sweden. Data for this section been provided by the. Atoms of the same element with different numbers of neutrons. Terbium compounds are currently used as luminescent probes in biological and biomedical research, but they emit visible light. Student Makes Stunning Discovery These isotopes are ytterbium-168, ytterbium-170, ytterbium-171, ytterbium-172, ytterbium-173, ytterbium-174, and ytterbium-176. It can be found in gadolinite, monazite, and xenotime. A measure of how difficult it is to deform a material. 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. This was achieved by heating erbium nitrate until it decomposed and then extracting the residue with water to obtain two oxides; a red one, which was identified as erbium oxide and a white powder, which was named ytterbium oxide. In 1843, erbium and terbium were extracted from it, and then in 1878, de Marignac separated ytterbium from erbium. Melting point Allotropes Explaining the exceptional chemistry of Ytterbium, here's Louise Natrajan. A higher recycling rate may reduce risk to supply. We welcome your feedback. Primary mining areas are USA, Canada, Greenland and Brazil. We hope that you enjoy your visit to this Site. Ytterbium melting point is 824OC and boiling poin… It has three allotropes forms: alpha, beta and gamma. Transition Metals Murray Robertson is the artist behind the images which make up Visual Elements. Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced. Yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. High = substitution not possible or very difficult. Group Density is the mass of a substance that would fill 1 cm 3 at room temperature. Some elements exist in several different structural forms, called allotropes. A second intriguing possibility is the use of elemental ytterbium is in super accurate atomic clocks. 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. Atomic mass of Ytterbium is 173.04 u.. 70. 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 transition of a substance directly from the solid to the gas phase without passing through a liquid phase. The RSC maintains this Site for your information, education, communication, and personal entertainment. A soft, silvery metal. Named after Ytterby, a village in Sweden. Isotopes Where the element is most commonly found in nature, and how it is sourced commercially. Boiling point Where more than one isotope exists, the value given is the abundance weighted average. It reacts slowly with cold water and it oxidizes slowly in air. It has low toxicity. Copyright of and ownership in the Images reside with Murray Robertson. Density is the mass of a substance that would fill 1 cm. The mass of an atom relative to that of carbon-12. Data for this section been provided by the British Geological Survey. Atomic number Copyright © 1996-2012 Yinon Bentor. In fact, Marignac's ytterbium oxide was not of a pure form either and a few years later in 1907, George Urbain extracted lutetium as its oxide from this ytterbium oxide. Atomic Number of Ytterbium. 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 cm3 at room temperature. Bismuth is a chemical element with atomic number 83 which means there are 83 protons and 83 electrons in the atomic structure. The temperature at which the solid–liquid phase change occurs. (1), (2)In 1907, in Paris, George Urbain separated ytterbia into two constituents. Ytterbium-169 in particular emits gamma rays. A horizontal row in the periodic table. agreement. Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Electronegativity (Pauling scale)The tendency of an atom to attract electrons towards itself, expressed on a relative scale. Values are given for typical oxidation number and coordination. The mass number, or the number of protons and neutrons, of ytterbium ranges from 148 to 181. This is approximately the sum of the number of protons and neutrons in the nucleus. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. Ytterbium has no known biological role. It can be extracted by ion exchange and solvent extraction. And in the moments of that intense explosion it produced a brand new element. Rubidium is a chemical element with atomic number 37 which means there are 37 protons and 37 electrons in the atomic structure. This is not to be confused with the relative percentage isotope abundances which totals 100% for all the naturally occurring isotopes. These values were determined using several different methods. This is approximately the sum of the number of protons and neutrons in the nucleus. Seven naturally occurring isotopes of ytterbium are known. If you are in any doubt, please ask. Ytterbium bromide (YbBr 3) Ytterbium chloride (YbCl 2) Ytterbium trichloride (YbCl 3) Ytterbium oxide (Yb 2 O 3) Interesting facts: It was discovered by separating gadolinite into three different materials: yttria, erbia and terbia. A tiny amount of ytterbium metal was made in 1937 by heating ytterbium chloride and potassium together but was impure. While, the most common oxidation state of the lanthanides is indeed the +3 valence state, ytterbium, the last and smallest of the lanthanides or rare earths in the series is one of the exceptions Pimentel and Sprately were talking about. Ytterbium is named after the town of Ytterby near Stockholm in Sweden, and makes up the fourth element to be named after this town, the others being of course yttrium, terbium and erbium. If you've listened to any of the other podcasts in the lanthanide series, I hope you'll agree that this is far from true. One atomic mass unit is equal to 1.66 x 10 -24 grams. Each allotrope has different physical properties. Ytterbium was discovered by Jean Charles Galinard de Marignac (CH) in 1878. Date of Discovery He heated erbium nitrate until it decomposed and then extracted the residue with water and obtained two oxides: a red one which was erbium oxide, and a white one which he knew must be a new element, and this he named ytterbium. 70 Yb Ytterbium Lanthanoid, mass: 173.04 u, 7 stable isotopes (168, 170, 171, 172, 173, 174, 176), abundance rank (earth/space): 55/67 Click image to magnify. It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system. When yttria was first identified, nobody realised that it was contaminated with traces of other rare earth metals. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all … 173.04 g.mol-1.
