yttrium (Y),chemical element, arare-earth metalof Group 3 of theperiodic table. Yttrium is a silvery white, moderately soft, ductilemetal. It is quite stable inair; rapid oxidation begins above approximately 450°C(840 °F), resulting in Y2O3. The metal readily reacts with dilutedacids—exce...
Xenon, Chemical Element XENON Photo by: www.fzd.it Overview Xenon is a noble gas. The term noble gas is used to describe the elements in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. "Noble gas"...
Platinum (Pt) is a chemical element with atomic number 78, located in Group 10, Periodic Table, Period 6. Platinum is a very heavy, precious, silvery-white metal that is soft and ductile, has a high melting point, and has good resistance to corrosion and chemical attack. Platinum has ant...
Mercury is a metal Element Mercury is a naturally occurring metallic chemical element. It is said that long ago, magma erupting from a volcano in Italy flowed down and cooled deep in the rock layers, and the water rose on its way to the surface. As the water rises, it leaves behind ...
Other applications include electrical contact points for car distributors, X-ray targets, windings and heating elements for electrical furnaces, missile and hightemperature applications, as alloying element in high-speed-tool steels (10%), and many other alloys. The two carbides (i.e., WC and ...
The absorption coefficient of an actinometric solution in the wavelength interval of the laser must be sufficiently high to allow full absorption of the light by the system in the layer. The layer thickness is equal to the diameter of the active element of the laser or of the photolytic ...
The wave function, Ψ, which describes the electron distribution around a given nuclear arrangement, not only can be used to compute the energy of the system, but also offers useful interpretation opportunities. III.B.1 Wave Function Analysis in Terms of Basis Functions Each MO ϕi (used to...
Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environm...
Tungsten is the bioelement with the highest atomic number 74, and the only bioelement in the third transition row of the periodic table.Tungsten is widely distributed in biology, however, it is not a universal bioelement, the majority of the tungsten-containing enzymes purified to date, origin...
Scandiumis a lightweight, relatively soft metal. The silver metal develops a yellow or pink tint after exposure to air. The element is used in the production of high intensity lamps. Read More Cool Chemical Element Facts By Anne Marie Helmenstine, Ph.D. Titanium - Element 22 This is a ba...
