Source: Scandium does not occur freely in nature, but in minute amounts in over 800 minerals. Rare minerals from Scandinavia and Madagascar (Thorveitite, euxenite, and gadolinite) are the only known concentrated sources of the element.
Similarly, where was the element scandium discovered?

Where does the name Thulium come from?
By Theodore Cleve of Sweden discovered holmium in 1879 while working on erbium earth (erbium oxide). Thulium oxide (Holmia) was present as an impurity in the Erbia. The element is named after Thule, the ancient name for Scandinavia.
What are some interesting facts about scandium?
This member of the transitional group is a silvery white historically classified as rare Earth Element. Interesting Facts About Scandium: Scandium was discovered in 1879 by Lars Fredrik Nilson, who named it after Scandinavia. Its existence was originally predicted by Dmitri Mendeleev ten years earlier.
Where does scandium come from?
It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite Scandinavia. Scandium is rarer in most depositsEarth and uranium compounds, but it is extracted from these ores in only a few mines worldwide.
Where was scandium discovered?
Scandium was discovered by Lars Frederick Nilson (a Scandinavian) in 1876 in the minerals euxenite and gadolinite, which had previously not been found anywhere except in Scandinavia. He and his colleagues were actually looking Rare earth metals.
Is scandium rare?
A bit of background: scandium is a chemical element with symbol Sc and atomic number 21. A silvery-white metallic element historically sometimes classified as a Rarely Earth element, along with yttrium and the lanthanides. Regarding the earth’s crust, scandium is not special Rarely.
How much is scandium worth?
Metallic scandium was first produced in 1937 and the first pound (0.45 kilograms) of pure scandium was produced in 1960. Scandium is a soft, light metal that could find application in the aerospace industry. With a cost of $270 per gram ($122,500 per pound) scandium is too expensive for widespread use.
What metal is scandium?
Scandium is a relatively soft, silver-white metal. Scandium is a silvery Metal, which is soft and has a density about three times that of water.
What is the use of niobium?
Niobium is used with iron and others elements in stainless steel alloys and also in alloys with a variety of non-ferrous metals, such as zirconium, niobium alloys are strong and commonly used in pipeline construction. The metal is used in super alloys for jet engines and heat-resistant devices.
Is scandium radioactive?
There is none radioactive isotopes of scandium usually found in nature. Like all elements synthetic radioactive isotopes of scandium exist. It occurs in thortveitite and in small amounts in other minerals.
Which family does scandium belong to?
Is scandium a solid?
Elements can be classified based on their physical states (States of Matter), e.g. gas, fixed or liquid. This item is a fixed. scandium is classified as a “transition metal” residing in groups 3 – 12 of the periodic table.
How do you get scandium?
It is present in minute amounts in many minerals, most notably monazite. However, it is only economical extract it from uranium ore residues and from the minerals euxenite, gadolinite and thortveitite. Most scandium not extracted from uranium residues is mined in Scandinavia, Iceland and Madagascar.
Where is yttrium commonly found on earth?
Yttrium never occurs naturally as a free element. Yttrium occurs in the ores of monazite sand [(Ce, La, etc.)PO4] and bastn°site [(Ce, La, etc.)(CO3)F], ores containing small amounts of all rares Earth metals as well as in some other ores. Difficult to distinguish from other rare specimens Earth Elements.
Where was iodine discovered?
discovery of iodine. Iodine was discovered by Bernard Courtois in 1811 France. Courtois tried to extract potassium chloride from seaweed. After crystallizing the potassium chloride, he added sulfuric acid to the remaining liquid.
Where was titanium discovered?
Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the titans of Greek mythology.
Where was niobium discovered?
Niobium was discovered in 1801 by Charles Hatchett in an ore called columbite England in the 1750s by John Winthrop the Younger, the first governor of Connecticut, UNITED STATES OF AMERICA. Hatchett named the new element columbium. He could not isolate the free element.
How many valence electrons does a scandium atom have?
scandium Z=21 has an electronic configuration [Ar] 4s 3d . Both the 4s and 3d electrons are easily mobilized for bonding, so we can conclude that Scandim did this three valence electrons.
What are the values of manganese?
manganese is a transition metal, meaning it can have more than one valence state. Its electron configuration is [Ar] 3W5 4S2. The two electrons in the 4s orbital are obviously valence electrons, so a valence state of 2+ is possible. manganese is a chemical element with a symbol Mn and atomic number 25.
Where was manganese discovered?
Proposed as an element by Carl Wilhelm Scheele in 1774, manganese was discovered by Johan Gottlieb Gahn, a Swedish chemist, by heating the mineral pyrolusite (MnO2) in the presence of charcoal later this year.
What is element 23?
Vanadium is a chemical element with symbol V and atomic number 23. It is a hard, silvery-grey, ductile, and malleable transition metal.
