Yttrium, the first rare-earth element In 1792 Gadolin received a sample of black, heavy mineral found in a quarry in a Swedish village Ytterby near Stockholm by Carl Axel Arrhenius.
When did Gadolin discovered yttrium?
1789
Yttrium was discovered by Johan Gadolin, a Finnish chemist, while analyzing the composition of the mineral gadolinite ((Ce, La, Nd, Y)2FeBe2Si2O10) in 1789. Gadolinite, which was named for Johan Gadolin, was discovered several years earlier in a quarry near the town of Ytterby, Sweden.
Who first discovered yttrium?

What is the 39th element?
Yttrium is a chemical element with symbol Y and atomic number 39. Classified as a transition metal, Yttrium is a solid at room temperature. 39. Y.
What yttrium is used for?
Yttrium is often used as an additive in alloys. It increases the strength of aluminium and magnesium alloys. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation.
What is the color of yttrium?
silvery white
Yttrium is a silvery white, moderately soft, ductile metal. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3.
What did Johan Gadolin discover?
Yttrium
Johan Gadolin/Discovered
Finnish chemist Johan Gadolin (1760–1852) often receives credit for the discovery of the element yttrium, a claim based on a paper published in 1794 detailing his recognition of a new earth, later named yttria, found in the chemical analysis of a mineral from a quarry in Ytterby, Sweden.
Who isolated yttrium?
Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element”….

What is yttrium worth?
Yttrium is currently worth $3,400 per pound, europium costs $20,000 per 100 grams and terbium sells for $1,800 per 100 grams.
What is the odor of yttrium?
Appearance and Odor: Yellow powder, rotten egg odor. Extinguishing Media: DO NOT USE WATER. Use CO2, sand, extinguishing powder.
What is yttrium (gadolinite)?
Gadolinite, which was named for Johan Gadolin, was discovered several years earlier in a quarry near the town of Ytterby, Sweden. Today, yttrium 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.
How was yttrium discovered?
Yttrium was discovered by Johan Gadolin, a Finnish chemist, while analyzing the composition of the mineral gadolinite ((Ce, La, Nd, Y) 2 FeBe 2 Si 2 O 10) in 1789. Gadolinite, which was named for Johan Gadolin, was discovered several years earlier in a quarry near the town of Ytterby, Sweden.
What is yttrium made of?
The Element Yttrium. Gadolinite, which was named for Johan Gadolin, was discovered several years earlier in a quarry near the town of Ytterby, Sweden. Today, yttrium 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.
What element did Gadolin originally call ytterbium?
In 1794, the Finnish chemist Johan Gadolin discovered yttrium in the mineral ytterbite, which was later renamed gadolinite for Gadolin. Gadolin originally called the element ytterbium after ytterbite. The name was subsequently shortened to yttrium, and later another element was given the name ytterbium.
