Johan Gadolin war ein finnischer Chemiker. Gadolin entdeckte im Jahre 1794 das erste chemische Element aus der Gruppe der Seltenen-Erd-Metalle, das Yttrium im Mineral Ytterbit, und war einer der ersten Verfechter von Lavoisiers Verbrennungstheorie in Skandinavien.
Where is yttrium found in the world?
Sources. Yttrium is present in nearly all rare-earth minerals. It is obtained by mining the minerals bastnasite, fergusonite, monazite, samarskite and xenotime, which are mined in the USA, China, Australia, India and Brazil.
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 did yttrium get discovered?
Elemental yttrium, in an impure form, was first isolated in 1828 by Friedrich Wöhler by passing chlorine gas over the gadolinite mineral to form anhydrous yttrium chloride (YCl3), which was in turn reduced to yttrium using potassium3.
When was discovered nitrogen?
Nitrogen was officially discovered in 1772 by Scottish scientist Daniel Rutherford [6]. At the same time however, Carl Scheele, Henry Cavendish, Joseph Priestley and others were investigating 'burnt or dephlogisticated air', as air without oxygen was then called.

What is the 70th element?
Ytterbium is a chemical element with symbol Yb and atomic number 70.
Where is scandium found?
Source: Scandium is not found free in nature but is found combined in minute amounts in over 800 minerals. Rare minerals from Scandinavia and Madagascar (thortveitite, euxenite, and gadolinite) are the only known concentrated sources of the element.
What is the history of yttrium?
Yttrium was named for Ytterby. In 1843, a Swedish chemist named Carl Gustaf Mosander studied yttrium samples and discovered they contained three oxides. At the time they were called yttria, erbia and terbia. They are now known as white yttrium oxide, yellow terbium oxide, and rose-colored erbium oxide, respectively.
Which country produces the most yttrium?
World Mine Production and Reserves:10 World mine production of yttrium contained in rare-earth mineral concentrates was estimated to be 10,000 to 14,000 tons. Most of this production took place in China and Burma. Global reserves of yttrium oxide were estimated to be more than 500,000 tons.
What color is yttrium?
Yttrium is a silvery white, moderately soft, ductile metal.
Where does Molybdenum come from?
The main molybdenum ore is molybdenite (molybdenum disulfide), but can also be found in wulfenite (lead molybdate) and powellite (calcium molybdate). It is recovered as a by-product of copper or tungsten mining. Molybdenum is mined primarily in the United States, China, Chile and Peru.
What is 89 on the periodic table?
Actinium gives its name to a block of fifteen elements that lie between actinium and lawrencium in the periodic table with atomic numbers 89 through 103.
What country discovered nitrogen?
Nitrogen was discovered by the Scottish physician Daniel Rutherford in 1772. It is the fifth most abundant element in the universe and makes up about 78% of the earth's atmosphere, which contains an estimated 4,000 trillion tons of the gas.
Why is yttrium called yttrium?
Yttrium has no known biological role. Exposure to yttrium compounds can cause lung disease in humans. The element is named after ytterbite, a mineral first identified in 1787 by the chemist Arrhenius. He named the mineral after the village of Ytterby, in Sweden, where it had been discovered.
Who named yttrium?
He found it contained 31% silica, 19% alumina, 12% iron oxide and 38% of an unknown earth. Gadolin's results were confirmed in 1797 by Swedish chemist Anders Ekeberg. Ekeberg suggested the name yttria for the oxide of the new earth metal and hence the new metal was named yttrium.
