Hereof, what elements does scandium bond with?

Scandium is very reactive towards the halogens fluorine, F2, chlorine, Cl2 bromine, Br2, and iodine, I2, and burns to form the trihalides scandium(III) fluoride, ScF3 , scandium(III) chloride, ScCl3, scandium(III) bromide, ScBr3, and scandium(III) iodide, ScI3 respectively.

Secondly, why does scandium only form 3+ ions? "Scandium forms the extremely stable Ar electron configuration when it loses 3 electrons, so the 3+ state is strongly favored."

One may also ask, what family does scandium belong to?

Name Scandium
Boiling Point 2832.0° C
Density 2.989 grams per cubic centimeter
Normal Phase Solid
Family Transition Metals

Why is scandium so expensive?

Scandium Price: Owing to its scarcity and limited production, scandium is one of the most expensive of all the natural elements. Prices for 99.99% pure scandium (RE: 99% min. The more widely commercially used form, scandium oxide (Sc2O3), meanwhile, was being offered at prices of over US$ 7000/kg.

Can scandium rust?

It does improve the engineering properties of the alloy, but there's very little actual scandium involved. The alloy can't rust, because there's no iron. Like other aluminum alloys, any surface oxidation that forums acts as a protective layer and prevents further degradation, so it's virtually maintenance free.

Why does the third period have 8 elements?

According to the Aufbau's Principle (the building up principle) there can be only EIGHT elements that satisfy this. This is because the S orbital of the fourth shell sits at a lower energy level (closer to the nucleus) than the d orbital of the third shell.

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.

What is the 21st element?


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.

What two elements have 10 neutrons?

The number of neutrons corresponding to the most common isotope of the element is in bold type. All beryllium atoms have 5 neutrons in the nucleus and all fluorine atoms have 10 neutrons. Most hydrogen atoms have no neutrons but the deuterium isotope (H-2) has 1 neutron and the tritium isotope (H-3) has 2 neutrons.

Where is scandium most commonly found?

Abundance and Isotopes
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.

Is scandium expensive?

With a cost of $270 per gram ($122,500 per pound), scandium is too expensive for widespread use. Alloys of scandium and aluminum are used in some kinds of athletic equipment, such as aluminum baseball bats, bicycle frames and lacrosse sticks. Scientists have only studied a few compounds of scandium.

What does scandium feel like?


Scandium is a silvery white, moderately soft metal. It is fairly stable in air but will slowly change its colour from silvery white to a yellowish appearance because of formation of Sc2O3 oxide on the surface. Scandium is paramagnetic from 0 K (−273 °C, or −460 °F) to its melting point (1,541 °C, or 2,806 °F).

What is yttrium used for?

The largest use of the element is as its oxide yttria, Y2O3, which is used in making red phosphors for color television picture tubes. Yttrium metal has found some use alloyed in small amounts with other metals and It is used to increase the strength of aluminium and magnesium alloys.

Where is scandium mined?

It is present in minute quantities in many minerals, notably monazite. However, it is only economical to extract it from uranium ore tailings and from the minerals euxenite, gadolinite and thortveitite. Most scandium not extracted from uranium tailings is mined in Scandinavia, Iceland and Madagascar.

How strong is scandium alloy?

The scandium containing aluminum alloys used in the present invention have the following properties: yield strengths of 82 KSI to 100 KSI, tensile strengths of 88 KSI to 106 KSI, 12% to 19% elongation's, and 7% to 10% reduction areas.

How do you say scandium?

Here are 4 tips that should help you perfect your pronunciation of 'scandium': Break 'scandium' down into sounds: [SKAN] + [DEE] + [UHM] - say it out loud and exaggerate the sounds until you can consistently produce them.

What is titanium made of?

Instead, it has to be made from mineral ores called ilmenite (a complex compound of iron, titanium, and oxygen with chemical formula FeTiO3) and rutile (mostly titanium dioxide, a compound of titanium and oxygen with chemical formula TiO2) using a series of chemical reactions that can be difficult and costly.
