Scandium Facts - Science Notes and Projects

Jun 09, 2015· Fun Scandium Facts. Scandium is a silvery-white relatively light and soft metal at room temperature. When exposed to air, pure scandium develops a pink-yellow oxidation layer. Scandium is used in alloys much like aluminum. Scandium has a higher melting point than aluminum while having nearly the same density.

Scandium - Wikipedia

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.It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia.. Scandium is present in most of the deposits of rare-earth and uranium ...

An Overview of Scandium (Sc or Element 21)

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 eka-boron. 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).

atomic weight | EVISA's Glossary

The nominal atomic weight of an isotope is given by the sum of the number of neutrons and protons in each nucleus. The exact atomic weight differs fractionally from that whole number, because neutrons are slightly heavier than protons and the mass of the nucleus is also affected by the binding energy.

Periodic Table of Elements and Chemistry - Chemicool

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

Rare Earths Statistics and Information - USGS

The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption 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 …

Chemical Fact Sheet: Scandium | EVISA's Links Database

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.

Scandium - Element information, properties and uses ...

Scandium is very much a late starter compared to many of the other elements, due to its relatively low occurrence and the difficulty in obtaining it from its ores. For example, it wasn't until the 1960s when the first pound, or 450 grams, of high purity scandium was obtained. Compounds of scandium find use in organic chemistry.
