You're listening to Chemistry in its element brought to you by. The blue color of beryl (aquamarine variety) is said to be due to scandium. The temperature at which the solid–liquid phase change occurs. DOT Number:  3089, Pronunciation:  Skan-dee-am Scandium is added in small amounts to aluminium, to produce an alloy which is very light, yet very strong. PLEASE, if you like an article we published simply link to it on our website do not republish it. It occurs as a principal component in the rare mineral thortveitite, found in Scandinavia and Malagasy. Atomic Mass Number – Does it conserve in a nuclear reaction? These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Element category:  Transition metal Values are given for typical oxidation number and coordination. al. CAS number Gadolinium may prove useful to the fridges of the future due to a process known as magnetic refridgeration or adiabatic demagnetisation. Covalent radius:  170±7 pm Fusion heat:  14.1 kJ/mol Pure scandium is now produced by reducing scandium fluoride with calcium metal.

It is extracted as a by-product from uranium mill tailings (the residue of something). A low resistivity indicates a material that readily allows the flow of electric current. Where more than one isotope exists, the value given is the abundance weighted average. These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. 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. m. Electrical resistivity and its converse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current. On the basis of the Periodic System, Mendeleev predicted the existence of ekaboron, which would have an atomic weight between 40 of calcium and 48 of titanium. The arrangements of electrons above the last (closed shell) noble gas.
