· This also adds confusion as the common scandium ion is ce{Sc^3+} which has no d electrons, so wouldn't be a transition element, yet it's my understanding scandium can display a +2 oxidation state also (albeit less commonly). What's the correct definition? Is scandium considered a transition metal or not? inorganicchemistry terminology transitionmetals. Share. Improve this .

Scandium Sc 21 About Scandium; Products; Properties; Safety; Isotopes ; About Scandium. On Dmitri Mendeleev's 1869 periodic table, element 21 appeared as "ekaboron". No such element had yet been discovered, but Mendeleev's predictions regarding its existence and properties were largely confirmed ten years later when Lars Fredrik Nilson detected it in the minerals euxenite ...
Scandium (Sc) is a silverywhite metal that has the atomic number 21 in the periodic table. It is a Transition metal and loed in Group 3 of the periodic table. It has the symbol Sc. Scandium is a transition metal part of the d electron block of the periodic table and is egorised as a rare earth metal that is only found in ores and not ...
· Facts about scandium element are mentioned below. Scandium is a silvery white colored moderately soft metal. When it is kept open in the air, it reacts very slowly with oxygen to form Sc 2 O 3 and its color changes from silvery white to yellowish color. Density of .
· The more widely used form in commercial appliions, scandium oxide (Sc 2 O 3), was recently offered at prices of around US7000/kg, which is in the range of 20year average. Depending on the percentage of the scandium alloying element, the price of the AlSc alloys are expected to cost between 30% more than nonscandium alloy (at scandium levels of between up to wt% as .
Scandium (atomic number 21, symbol Sc) is a rare transition metal with a silvery white color. Other rare elements are lutetium, ytterbium, thulium, erbium, and holmium. It is considered a rare element because it occurs in the same ores as other rare earth elements and has the same properties. The metal was discovered by the Swedish chemist Lars Fredrik Nilson in 1879. He was the first to ...

Scandium (IPA: /ˈskandiəm/) is a chemical element in the periodic table that has the symbol Sc and atomic number 21. A soft, silvery, white metal, scandium ore occurs in rare minerals from Scandinavia and elsewhere, and it is sometimes considered along with yttrium, and the lanthanides and actinides, to be a rare earth. Scandium is a rare, soft, silvery, very light metallic element that ...
Scandium Sc (Element 21) of Periodic Table. Scandium is a soft, silver transition metal, which develops a slightly yellowish or pinkish cast upon exposure to air. It tarnish in air, where it reacts and readily forms a white coating of nitride, and when once ignite it burn easily with a yellowred flame. It reacts with water to form hydrogen gas ...
· Characteristics of scandium. Its atomic number is 21 . Its atomic mass is (g / mol). Its density is Its boiling point happens at 2730 ° C and its melting point at 1539 ° C. The symbol that represents it in the periodic table is Sc and its atomic weight is 44,956. The main mineral that forms scandium is thortveitite, which can be found in granite formations and in some tin ...
Scandium can be obtained from the minerals thortveitite ((Sc, Y) 2 Si 2 O 7), bazzite (Be 3 (Sc, Al) 2 Si 6 O 18) and wiikite, but is usually obtained as a byproduct of refining uranium. Metallic scandium was first produced in 1937 and the first pound ( kilograms) of pure scandium was produced in 1960. Scandium is a soft, light metal that might have appliions in the aerospace industry ...
For example, Mendeleev predicted the element's molecular weight would be 44 and that it would form one oxide with formula Eb 2 O 3; scandium has molecular weight 45, and forms scandium oxide, Sc 2 O 3. Some of Mendeleev's predictions were even more detailed. He predicted that the carbonate of ekaboron would not be soluble in water, which scandium carbonate is not. He even made a prediction ...
· Scandium precipitates from water as the insoluble hydroxide, Sc(OH) 3, even at pH 7. Thus, there have been no geological processes to concentrate this element and its presence has been detected in more than 800 minerals. Pure scandium specimens are rare and highly sought after by collectors. Crystals of the greenishblack thortveitite, Sc 2 Si 2 O 7, are particularly expensive. Traces .

A relatively soft element, scandium resembles yttrium and the rareearth metals more than it resembles aluminum or titanium. It is a very light metal and has a much higher melting point than aluminum, making it of interest to designers of spacecraft. Scandium is not attacked by a 1:1 mixture of HNO 3 and 48% HF. Costs. Scandium oxide costs about 75/g. Uses. About 20 kg of scandium (as Sc 2 O ...
