Ytterbium was discovered in what year?
Gefragt von: Barbara Giese-Bayer | Letzte Aktualisierung: 16. April 2022sternezahl: 4.1/5 (2 sternebewertungen)
Ytterbium ist ein chemisches Element mit dem Elementsymbol Yb und der Ordnungszahl 70. Im Periodensystem steht es in der Gruppe der Lanthanoide und zählt damit auch zu den Metallen der Seltenen Erden. Wie die anderen Lanthanoide ist Ytterbium ein silberglänzendes Schwermetall.
Where is ytterbium discovered?
The first concentrate of ytterbium was obtained in 1878 by Swiss chemist Jean-Charles Galissard de Marignac and named by him for the town of Ytterby, Sweden, where it (and the first discovered rare-earth element, yttrium) was found.
How was discovered ytterbium?
Ytterbium was discovered by Jean Charles Galissard de Marignac in 1878, in Geneva, Switzerland. He heated erbium nitrate until it decomposed and then extracted the residue, which contained an unknown white powder that he named ytterbium oxide (ytterbia).
Who discovered ytterbium on the periodic table?
Background. A French chemist Jean-Charles-Galissard de Marignac discovered the element named ytterbium. Erbium nitrate was heated by de Marignac until it totally decomposed, followed by extraction of the residue from which two oxides were obtained. One oxide was called erbium oxide and the other was named ytterbium.
Where is ytterbium used?
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.

Where is ytterbium on the periodic table?
Ytterbium is a chemical element with symbol Yb and atomic number 70. Classified as a lanthanide, Ytterbium is a solid at room temperature.
How is ytterbium used in everyday life?
Uses of ytterbium include use as a radiation source for x-ray machines. It is added to stainless steel to improve its mechanical properties. It may be added as a doping agent to fiber optic cable. It is used to make certain lasers.
Is ytterbium rare or common?
Ytterbium occurs along with other rare earths in a number of rare minerals. It is commercially recovered principally from monazite sand, which contains about 0.03 percent. Ion-exchange and solvent extraction techniques have simplified the separation of the rare earths from one another.
How much is ytterbium worth?
It is expected that the price of ytterbium oxide will reach some 69 U.S. dollars per kilogram in 2017.
Is ytterbium a rare earth metal?
Ytterbium is a soft, malleable and rather ductile element that exhibits a bright silvery luster. A rare earth, the element is easily attacked and dissolved by mineral acids, slowly reacts with water, and oxidizes in air.
What is made from ytterbium?
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.
Is ytterbium natural or synthetic?
It is a rare earth metal, which despite its name, does not mean that it is hard to find. Rare earth metals are really hard to separate from each other. That's why it took over 70 years to obtain a pure sample! Ytterbium has seven natural isotopes and twenty seven artificial isotopes.
What is the difference between yttrium and ytterbium?
Yttrium is a chemical element having the symbol Y and atomic number 39, while Ytterbium is a chemical element having the symbol Yb and atomic number 70. The key difference between Yttrium and Ytterbium is that natural yttrium is non-radioactive, whereas ytterbium is usually radioactive.
What's the cost of dysprosium?
In 2020 the price of dysprosium oxide was 260 U.S. dollars per kilogram. There are 17 rare earth elements and although they are fairly abundant in the Earth's crust, often they occur at sparse intervals are are less economically exploitable.
What is dysprosium used for?
Dysprosium is used in control rods for nuclear reactors because of its relatively high neutron-absorption cross section; its compounds have been used for making laser materials and phosphor activators, and in metal halide lamps.
How was dysprosium discovered?
Dysprosium was discovered in 1886 by Paul-Émile Lecoq de Boisbaudran in Paris. Its discovery came as a result of research into yttrium oxide, first made in 1794, and from which other rare earths (aka lanthanoids) were subsequently to be extracted, namely erbium in 1843, then holmium in 1878, and finally dysprosium.
Where did the name dysprosium originate from?
Word origin: From dysprositos, which means “difficult to get at” in Greek. Discovery: Dysprosium was discovered in 1886 by French chemist Paul-Émile Lecoq de Boisbaudran, but he was not able to isolate it.
Where was dysprosium found?
Sources. Dysprosium is chiefly obtained from bastnasite and monazite, where it occurs as an impurity. Other dysprosium-bearing minerals include euxenite, fergusonite, gadolinite and polycrase. It is mined in the USA, China Russia, Australia, and India.
What is the oldest element?
The oldest chemical element is Phosphorus and the newest element is Hassium.
How is cerium purified?
Probably the best known and most widely used techniques for cerium purification are those based on the oxidation of cerium in solution to the tetravalent state. Persulfates , permanganates, and hypochlorites are frequently used for this oxidation reaction.
Where is cerium found in the world?
Cerium is one of the most abundant of the rare-earth metals. It is found in several minerals, including allanite or orthrite, monazite, bastnasite, cerite and samarskite. Large deposits of cerium have been found in India, Brazil and in Southern California.
What are some fun facts about dysprosium?
- Paul Lecoq de Boisbaudran identified dysprosium in 1886, but it wasn't isolated as a pure metal until the 1950s by Frank Spedding. ...
- At room temperature, dysprosium is a bright silver metal that slowly oxidizes in air and readily burns.
How much is indium worth?
The present cost of indium is about $1 to $5/g, depending on quantity and purity.
