what does 'Tungsten' mean?
603266
Tungsten (W) is a metal with a wide range of uses, the largest of which is as tungsten carbide in cemented carbides. Cemented carbides (also called hardmetals) are wear-resistant materials used by the metalworking, mining, and construction industries. Tungsten metal wires, electrodes, and/or contacts are used in lighting, electronic, electrical, heating, and welding applications.

Tungsten has at least three times the melting point of copper, and they are both conductors, but when it comes to electricity, Copper is the winner, because Tungsten has more resistance to electricity therefore it is less conductive than Copper.\n\nTungsten due to its resistance is used in Light bulbs,\nand copper, which is more malleble  is used in mostly covering wires.\n\nHope it helps,

I don't think it's a "double meaning". It just means that not all things that look attractive are good or valuable.\n\nFor example, cheap crystal glitters, but you really shouldn't try proposing to your girlfriend with that.

S690/WTP80C:\n\nS690 is a reference to a high-strength steel.\nWTP80C is a chemical composition for a Chinese-produced "equivalent" steel, would be my guess.\n\nComposition of WTP80C (quantities are in percent):\nCarbon < 0.18\nSilicon 0.15-0.35\nManganese 0.6 - 1.20\nPhosphorus < 0.30\nSulfur < 0.030\nCopper 0.15 - 0.50\nChromium 0.70 - 1.3\nMolybdenum < 0.60\nBoron < 0.006\nNickel ... unlisted

Many of our metals are solid and homogeneous.  Homogeneous does not mean pure (only one thing) -- it only means that the composition is the same throughout the object.\n\nSo gold yes, or silver.  Also many wooden objects, glass, some food items like the center of bread...  The list goes on forever once you start thinking.

If you mean metal carbides, they are normally manufactured similar to other metal alloys using tungsten, iron, aluminum, or other metals.

Tungsten carbide is an alloy of (guess what) tungsten and carbon. It's extremely hard so it's used to coat cutting blades and for sandpaper. It's used as a surface coating because it's scratch resistant.\n\nAnd it's much cheaper than gold.

It isn't the only material for light filaments but it is the most used material. \n\nThe lamp industry represents the largest commercial application of tungsten wire. It is used in this application because it displays excellent creep resistance at elevated temperatures. Tungsten is an attractive lamp filament material because it has an extremely high melting temperature (~3,695 K) and a low vapour pressure at high temperatures. Tungsten is also intrinsically brittle and, initially, this prevented the manufacture of tungsten wire.  But advances in metallurgy enabled tungsten wire and coil filaments to be handled without breakage, so tungsten became the backbone of the whole incandescent lamp industry.

Pewter is a metal alloy, traditionally between 85 and 99 % tin, with the remainder consisting of 1-4 % copper, acting as a hardener, with the addition of lead for the lower grades of pewter and a bluish tint. There were three grades: Fine, for eatingware, with 96-99 % tin, and 1-4 % copper; Trifle, also for eating and drinking utensils but duller in appearance, with 92 % tin, 1-4 % copper, and up to 4 % lead; and Lay or Ley metal, not for eating or drinking utensils, which could contain up to 15 % lead. Modern pewter mixes the tin with copper, antimony and/or bismuth, as opposed to lead. Bismuth and zinc can also be added to pewter. Pewter cannot be used to make tools.

see [Xe] means the element xenon . before 4f14 5d10 6s1 the electronic configuration is same as that of xenon.it is just for the sake of conveniance that it is written like this.\nnow if u know the EC of xenon just add 4f14 5d10 6s1(i hope that u understand what that means.)after the EC of xenon and u get the EC of gold.\n4f14 5d10 6s1 maens that in gold,the 4th f orbital has 14 electrons 5th  d orbital has 10 electrons in it and the 6ths orbital has 1 electron.well i tried my best to tell u \nfor further queries e mail me at koolguyrik@yahoo.co.in

It is don't take any wooden nickles and it refers to a period of time just after WWI. Because the metal nickle is used in military applications, United States mint ran out of the metal. I order to satusfy the law for printing nickles wooden 5 cent pieces were produced for a short period of time. \n\nPeople thought it was a joke that the wooden coin was not worth anything hence the saying "Don't take any wooden nickles."

Polonium:\n\npo·lo·ni·um (pə-lō'nē-əm) pronunciation\nn. (Symbol Po)\n\nA naturally radioactive metallic element, occurring in minute quantities as a product of radium disintegration and produced by bombarding bismuth or lead with neutrons. It has 27 isotopes ranging in mass number from 192 to 218, of which Po 210, with a half-life of 138.39 days, is the most readily available. Atomic number 84; melting point 254°C; boiling point 962°C; specific gravity 9.32; valence 2, 4.\n\n[From Medieval Latin Polōnia, Poland (the native country of Pierre and Marie Curie, the element's discoverers).]\nPolonium\n\nA chemical element, Po, atomic number 84. Marie Curie discovered the radioisotope 210Po in pitchblende. This isotope is the penultimate member of the radium decay series. All polonium isotopes are radioactive, and all are shortlived except the three ?-emitters, artificially produced 208Po (2.9 years) and 209Po (100 years), and natural 210Po (138.4 days). See also Periodic table.\n\nPolonium (210Po) is used mainly for the production of neutron sources. It can also be used in static eliminators and, when incorporated in the electrode alloy of spark plugs, is said to improve the cold-starting properties of internal combustion engines.\n\nMost of the chemistry of polonium has been determined using 210Po, 1 curie of which weighs 222.2 micrograms; work with weighable amounts is hazardous, requiring special techniques. Polonium is more metallic than its lower homolog, tellurium. The metal is chemically similar to tellurium, forming the bright red compounds SPoO3 and SePoO3. The metal is soft, and its physical properties resemble those of thallium, lead, and bismuth. Valences of 2 and 4 are well established; there is some evidence of hexavalency. Polonium is positioned between silver and tellurium in the electrochemical series.\n\nTwo forms of the dioxide are known: low-temperature, yellow, face-centered cubic (UO2 type), and high-temperature, red, tetragonal. The halides are covalent, volatile compounds, resembling their tellurium analogs.polonium (pəlō'nēəm) , radioactive chemical element; symbol Po; at. no. 84; mass no. of most stable isotope 209; m.p. 254°C; b.p. 962°C; sp. gr. about 9.4; valence +2 or +4. Polonium is an extremely rare element found in uranium ores (about 0.1 gram per ton). A product of radium decay, it is sometimes called radium F. In its physical and chemical properties it resembles tellurium (the element above it in Group 16 of the periodic table) and bismuth. Polonium has 34 isotopes, more than any other element. All of these isotopes are radioactive. The most stable, polonium-209, has a half-life of about 103 years. Polonium-208 (half-life about 3 years) is the only other polonium isotope with a half-life over one year. Although these two isotopes can be prepared in small quantities in a particle accelerator, they are very expensive to produce. All other polonium isotopes are short-lived except polonium-210 (half-life about 138 days), which is the most commonly used isotope. It is prepared by bombarding bismuth with neutrons in a nuclear reactor. It is a highly radioactive material. A milligram of polonium-210 emits as much alpha radiation as about 5 grams of radium, and enough gamma radiation to cause a blue glow in the air around it. It can be used as a heat source, since most of the energy of the alpha radiation is absorbed as heat within the polonium and its container. Polonium has found use in small portable radiation sources and in the control of static electricity. However, it is an extremely toxic substance and must be handled with great care. Polonium was the first element to be discovered because of its radioactivity; it was discovered in pitchblende in 1898 by Marie Curie and named for her native country, Poland.A naturally radioactive metallic element, occurring in minute quantities in uranium ores; its most readily available isotope is Po 210, with a half-life of 138.39 day
