What are 3 uses for lutetium?
Lutetium is used in research. Its compounds are used as hosts for scintillators and X-ray phosphors, and the oxide is used in optical lenses. The element behaves as a typical rare earth, forming a series of compounds in oxidation state +3, such as lutetium sesquioxide, sulfate, and chloride.
Does the human body use lutetium?
Lutetium has no biological role but is said to stimulate the metabolism.
Is lutetium a reactivity?
Lutetium metal is slightly unstable in air at standard conditions, but it burns readily at 150 °C to form lutetium oxide. Lutetium metal is known to react with the four lightest halogens to form trihalides; all of them (except the fluoride) are soluble in water.
Why is lutetium in F block?
Lutetium is part of the lanthanide series, notwithstanding its electron configuration, because its properties and those of its compounds are similar to those of the other lanthanide elements. Lawrencium is assigned to the actinides for basically the same reason.
What are 5 uses for lutetium?
Lutetium oxide is used to make catalysts for cracking hydrocarbons in the petrochemical industry. Lu is used in cancer therapy and because of its long half-life, 176Lu is used to date the age of meteorites. Lutetium oxyorthosilicate (LSO) is currently used in detectors in positron emission tomography (PET).
Why is lutetium so expensive?
Fast Facts: The Most Expensive Natural Elements The most expensive natural element is francium, but it decays so quickly it can’t be collected to be sold. If you could buy it, you’d pay billions of dollars for 100 grams. The most expensive natural element that is stable enough to purchase is lutetium.
Who found lutetium?
Lutetium was actually the last lanthanide to be isolated in 1907; and was simultaneously discovered by three chemists working in different parts of the world. They were the Austrian Carl Auer von Welsbach, the American Charles James, and Georges Urbain from France.
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
Is Lutetium man made?
Discovery of Lutetium. Lutetium was the last natural rare earth element to be discovered. The synthetic rare earth promethium was produced later in the laboratory from uranium fission products. Lutetium was independently discovered by Carl Auer von Welsbach, Charles James, and Georges Urbain.
What is the rarest element in the Earth?
What is the most expensive element on Earth?
The most expensive natural element is francium. Although francium occurs naturally, it decays so quickly that it cannot be collected for use. Only a few atoms of francium have been produced commercially, so if you wanted to produce 100 grams of francium, you could expect to pay a few billion U.S. dollars for it.
