What are 3 uses of 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.
What are 3 interesting facts about scandium?
Fun Scandium Facts
- Scandium is a silvery-white relatively light and soft metal at room temperature.
- Scandium is used in alloys much like aluminum.
- Scandium is considered a rare-earth element because it is often found in rare-earth ores.
- Scandium is the 35th most abundant element in the Earth’s crust.
Where do we find scandium?
However, scandium is distributed sparsely and occurs in trace amounts in many minerals. 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.
What is the importance of scandium?
Scandium is mainly used for research purposes. It has, however, great potential because it has almost as low a density as aluminium and a much higher melting point. An aluminium-scandium alloy has been used in Russian MIG fighter planes, high-end bicycle frames and baseball bats.
Why is scandium a paramagnetic?
Hence, there is an unpaired electron in the 3d orbital of scandium. Hence, scandium is paramagnetic.
What are the physical and chemical properties of scandium?
These physical and chemical properties of scandium are mentioned below:
- It appears to be a silvery-white metal.
- It has a moderately soft texture.
- Scandium tarnishes in the air.
- It also burns easily.
- Scandium reacts with water.
- The electronic configuration of Scandium is Ar3d14s2.
- The melting point of the metal is 1541oC.
What is an interesting fact about yttrium?
Interesting Yttrium Facts: This mineral was found in Ytterby, Sweden, giving it its name. In 1828, Friedrich Wohler extracted an impure sample of yttrium by reducing anhydrous chloride and potassium. Yttrium is a transition metal that is often called a rare earth element.
What is scandium reactivity?
Named after Scandinavia, scandium is a soft, silvery-white metal. It is reactive and will tarnish to a yellowish or pinkish color in air. If water is run over it, a reaction that releases hydrogen gas will result. Scandium is also very reactive with acids.
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.
How does scandium react with water?
Reaction of scandium with water When finely divided, or heated, scandium metal dissolves in water to form solutions containing the aquated Sc(III) ion together with hydrogen gas, H2.
How many ions does scandium have?
Scandium’s electron config is [Ar] 3p6 4s2 3d1 . It can’t lose 2 electrons to form a positive ion because it can cause destabilization. It can form a +3 ion to achieve a noble gas configuration.
What are some physical properties of scandium?
Scandium Basic Facts. Sc-45 is the only stable isotope. Properties: Scandium has a melting point of 1541 °C, boiling point of 2830 °C, specific gravity of 2.989 (25 °C), and valence of 3. It is a silvery-white metal which develops a yellowish or pinkish cast when exposed to air. Scandium is a very light, relatively soft metal.
What are the physical characteristics of scandium?
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.
What are facts about scandium?
Interesting Facts about Scandium. Scandium is the transition metal having the lowest atomic number. Scandium was called after Scandinavia . Chemist Lars Nilson was trying to isolate the component ytterbium from the minerals euxenite and gadolinite when he found scandium. These minerals were mostly found in the Scandinavia area.
How is scandium used in everyday life?
Uses of Scandium in Everyday Life – Properties – General Uses. Those lamps give an effect of high intensity white light that is quite similar to a natural sunlight. Scandium oxide: Scandium oxide is used to make high intensity stadium lights. The radioactive isotope Scandium-46: The radioactive isotope is used as a tracing agent in oil refineries.
