Where is scandium from?
Rare minerals from Scandinavia and Madagascar such as thortveitite, euxenite, and gadolinite are the only known concentrated sources of this element. Thortveitite can contain up to 45% of scandium in the form of scandium oxide. The stable form of scandium is created in supernovas via the r-process.
What is the scandium family name?
|Cost||$75 per gram|
When was scandium discovered and by who?

What does the word scandium mean?
: a silvery-white metallic element found widely especially in association with rare earth elements and used especially in alloys and in high-intensity electric lamps — see Chemical Elements Table.
Is scandium harmful to humans?
Health effects of scandium Scandium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Scandium can be a threat to the liver when it accumulates in the human body.
What are 3 uses for scandium?
Scandium is used in aluminum-scandium alloys for aerospace industry components and for sports equipment such as bicycle frames, fishing rods, golf iron shafts and baseball bats. Scandium iodide is used in mercury vapor lamps, which are used to replicate sunlight in studios for the film and television industry.
Is scandium positive or negative?
Scandium is paramagnetic from 0 K (−273 °C, or −460 °F) to its melting point (1,541 °C, or 2,806 °F). It becomes superconducting at −273.1 °C (−459.6 °F) at pressures exceeding 186 kilobars….scandium.
|specific gravity||2.989 (24 °C, or 75 °F)|
Why is scandium so expensive?
Owing to its scarcity and limited production, scandium is one of the most expensive of all the natural elements. During the rare earth shortage of 2010, the price for scandium metal soared from a few thousand US dollars to over US$ 15,000 per kilogram.
Is scandium rare?
Scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. While named rare earths, they are in fact not that rare and are relatively abundant in the Earth’s crust.
Does the human body use scandium?
Scandium has no biological role. Scandium can be a threat to the liver when it accumulates in the human body.
How did the metal scandium get its name?
Origin of name : from the Latin word ” Scandia ” meaning ” Scandinavia “. Scandium was discovered by Lars Frederick Nilson (a Scandinavian) in 1876 in the minerals euxenite and gadolinite, which had not yet been found anywhere except in Scandinavia. He and his coworkers were actually looking for rare earth metals.
How did Lars Fredrik Nilson get the name scandium?
He called it ekaboron (boron like) and suggested some physical and chemical properties in 1869. Lars Fredrik Nilson and his team, in 1879 found this element in the minerals of euxenite and gadolinite. He prepared scandium oxide of high purity. The word scandium has been derived from Latin Scandia meaning Scandinavia .
How is scandium classified as a rare earth element?
talk. edit. | references. Scandium is a chemical element with the symbol Sc and atomic number 21. A silvery-white metallic d-block element, it has historically been classified as a rare-earth element, together with yttrium and the lanthanides.
Who was the first person to discover scandium?
In the same year, the Swedish chemist Per Theodore Cleve proved that scandium was Mendeleev’s predicted “eka-boron”. Scandium was discovered by Lars Fredrik Nilson, a Swedish chemist, in 1879 while attempting to produce a sample of pure ytterbia from 10 kilograms of the mineral euxenite ( (Y, Ca, Er, La, Ce, U, Th) (Nb, Ta, Ti) 2 O 6 ).
