Yttrium is a highly crystalline irongray, rareearth metal. Yttrium is fairly stable in air, because it is proteced by the formation by the formation of a stable oxide film on its surface, but oxidizes readily when heated. It reacts with water decomposing it to release hydrogen gas, and it reacts with mineral acids.

Yttrium: Yttrium (Y), chemical element, a rareearth metal of Group 3 of the periodic table. Yttrium is a silvery white, moderately soft, ductile metal. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3. The metal readily reacts with diluted
Scandium was discovered by Lars F. Nilson in 1879, in Uppsala, Sweden. Nilson was studying the rare earth elements, attempting to isolate ytterbium from the minerals euxenite and gadolinite.. Part of Nilson's method required the preparation of erbia (erbium oxide) from the minerals, which was then reacted to form erbium nitrate.

Except as a raw material for the Tungsten Plating (see Usage, Beryllium has only a few use. But it can be used in the Chemical Fusion Chamber and Chemical Fission Chamber...
The rare earth metals or the rare earth elements have many similar properties that often cause them to be found together in geologic deposits. The rare earth elements (REEs) are comprised of the lanthanide elements plus scandium and yttrium, which have similar physical properties and are often found in the same ores and deposits.

Beryllium is a Group 2 leadgray colored metal with a very high melting point of 1287 °C (2349 °F). Interesting Beryllium Facts: It is a hard metal, but is brittle at room temperature. Beryllium salts have a sweet taste, and the element was once called glucine with a symbol of Gl due to its flavor.
Aug 30, 2018· Therefore electronic configuration of scandium(Sc) is: 1s2 2s2 2p6 3s2 3p6 3d1 4s2. Here, two electrons are in 4s orbital instead of being in 3d orbital because 4s orbital is having lesser energy than 3d orbital and 4s orbital also gives fullfilled stability which 3d can not give.
Scandium is a chemical element with symbol Sc and atomic number 21. A silverywhite metallic dblock element. Scandium is present in most of the deposits of rareearth and uranium compounds, but it is extracted from these ores in only a few mines worldwide.
This is a process for extracting scandium from zircon ore. It utilizes feeding zircon sand to a fluidized bed chlorinator at about 1000° C. to produce a vaporous (principally zirconium and silicon chlorides) phase and a solid residue and recovering scandium from the solid residue. Surprisingly, despite the relatively low sublimation temperature of scandium chloride the very low level of ...
