He called this new element ekasilicon, after observing a gap in the periodic table between silicon and tin: Similarly, Mendeleev discovered gallium (ekaaluminum) and scandium (ekaboron) on paper, because he predicted their existence and their properties before their actual discoveries.

Jun 09, 2015· Scandium is considered a rareearth element because it is often found in rareearth ores. It also shares many of the same chemical properties of other rareearths. Scandium is the 35th most abundant element in the Earth’s crust. Scandium is the 23rd most abundant element in the Sun. Scandium is the first of the transition metals.
Scandium is a metal that has many of the characteristics of the rare earth elements, particularly yttrium. It is a light material with a higher melting point than aluminum, giving it uses in aerospace and other manufacturing, such as racing bicycles, baseball bats, and golf clubs.

The primary use for scandium today is in solid oxide fuel cells ("SOFCs"), where both of these attributes dramatically improve performance. Incorporation of scandium in SOFCs delivers higher power outputs and promotes the desired chemical reaction at a lower operating temperature, resulting in dramatically improved unit life cycles.
Scandium is the transition metal with the lowest atomic number. The discovery of scandium filled a spot predicted by Mendeleev's periodic table. Scandium took the place of the placeholder element ekaboron. Most scandium compounds have scandium with the Sc 3+ ion. Scandium has an abundance in the Earth's crust of 22 mg/kg (or parts per million).
Scandium is a silverywhite metal that develops a yellow or pink tint when exposed to air. It is relatively soft and is chemically similar to the rare earth metals. Scandium's light weight and high melting point suggest applications within the aircraft industry. Chemical Name: Scandium. Chemical Formula: Sc

May 16, 2016· In fact, it is found most prominently as a trace in iron ( and niobium) deposits associated with its chemical sister elements, the rare earths and yttrium, which in fact is chemically the nearest to scandium; they are both in, and constitute, a “column” in the Mendeleev version of the periodic table of the chemical elements. The scandium in ...

The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ionadsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's

Scandium Scandium is a soft, silvery transition element which occurs in rare minerals from Scandinavia. It develops a slightly yellowish or pinkish cast when exposed to air. Scandium tarnished in air and burn easily, once it has been ignited. It reacts with water to form hydrogen gas and will dissolve in many acids.
Scandium is the first element in the fourth period of the transition element. It is the 42nd most abundant element found in the Earths crust. Scandium is a soft, lightweight, silverywhite metal with the chemical …
Metallic scandium was first prepared in 1937 by Fischer, Brunger, and Grieneisen, who electrolyzed a eutectic melt of potassium, lithium, and scandium chlorides at 700 to 800 deg C. Tungsten wire and a pool of molten zinc served as the electrodes in a graphite crucible. Pure scandium is now produced by reducing scandium fluoride with calcium metal.
