[11], Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. What does nickle mean? [95][96], Nickel released from Siberian Traps volcanic eruptions is suspected of assisting the growth of Methanosarcina, a genus of euryarchaeote archaea that produced methane during the Permian–Triassic extinction event, the biggest extinction event on record.[97]. [62] In the first full year of operation, the Eagle Mine produced 18,000 t.[62]. A hard malleable ductile silvery metallic element that is resistant to corrosion; used in alloys; occurs in pentlandite and smaltite and garnierite and millerite. [45] Coins of nickel-copper alloy were minted by the Bactrian kings Agathocles, Euthydemus II, and Pantaleon in the 2nd century BCE, possibly out of the Chinese cupronickel. Coins of nearly pure nickel were first used in 1881 in Switzerland. Bronzes from what is now Syria have been found to contain as much as 2% nickel. ... nickel backs (English) Nickel-78's half-life was recently measured at 110 milliseconds, and is believed an important isotope in supernova nucleosynthesis of elements heavier than iron. [77], Around 27% of all nickel production is destined for engineering, 10% for building and construction, 14% for tubular products, 20% for metal goods, 14% for transport, 11% for electronic goods, and 5% for other uses. (Amer. Springborn Laboratories Inc., Spencerville. The first large-scale smelting of nickel began in Norway in 1848 from nickel-rich pyrrhotite. پانچ سینٹ کا امریکی سکہ: 3) nickel. Eng.) Nickel is the top confirmed contact allergen worldwide, partly due to its use in jewelry for pierced ears. nickel bag (English) a silver-white alloy containing copper and zinc and nickel Synonyms: German silver, Neighbors. nickel silver (uncountable) [110] In the rodent inhalation studies with various nickel compounds and nickel metal, increased lung inflammations with and without bronchial lymph node hyperplasia or fibrosis were observed. Nickel was also occasionally used in some countries after 1859 as a cheap coinage metal (see above), but in the later years of the 20th century, it was replaced by cheaper stainless steel (i.e. Plural of nickel note. iron) alloys, except in the United States and Canada. Plural of nickel bag. As of September 19, 2013, the melt value of a US nickel (copper and nickel included) is $0.045, which is 90% of the face value. [94] Relatively large amounts of nickel – comparable to the estimated average ingestion above – leach into food cooked in stainless steel. )…, kawa: …鈹: Matte: the molten metal sulfide phases typically formed during smelting of copper, nickel, and other base metals. Nickel(II) chloride is produced by dissolving nickel or its oxide in hydrochloric acid. Don't request for help, don't ask questions or complain. نقلی چاندی : 2) nickel. Many earrings are now made without nickel or with low-release nickel[122] to address this problem. A further 10% is used for nickel-based and copper-based alloys, 7% for alloy steels, 3% in foundries, 9% in plating and 4% in other applications, including the fast-growing battery sector,[8] including those in electric vehicles (EVs). Noun Nickel is an excellent alloying agent for certain precious metals and is used in the fire assay as a collector of platinum group elements (PGE). [29], Identified land-based resources throughout the world averaging 1% nickel or greater comprise at least 130 million tons of nickel (about the double of known reserves). [39] Ni(IV) remains a rare oxidation state of nickel and very few compounds are known to date. There are no user-contributed notes for this entry. A second common refining process is leaching the metal matte into a nickel salt solution, followed by the electro-winning of the nickel from solution by plating it onto a cathode as electrolytic nickel. If you are a general user or webmaster, and want to know how it works? [104][106][110][111] In rat studies, oral ingestion of water-soluble nickel salts can trigger perinatal mortality effects in pregnant animals. Symbol: Ni; atomic weight: 58.71; atomic number: 28; specific gravity: 8.9 at 20°C. Noun. Information and translations of nickle in the most comprehensive dictionary definitions resource on … nickel back (pl. [37] Further, Ni(III) forms simple salts with fluoride[38] or oxide ions. [118][119], Sensitized individuals may show a skin contact allergy to nickel known as a contact dermatitis. Noun Nickel(II) forms compounds with all common anions, including sulfide, sulfate, carbonate, hydroxide, carboxylates, and halides. Translations nickel - to plate with nickel. [citation needed], At least 26 nickel radioisotopes have been characterised, the most stable being 59Ni with a half-life of 76,000 years, 63Ni with 100 years, and 56Ni with 6 days. The average daily exposure does not pose a threat to human health. [10] Nickel is an essential nutrient for some microorganisms and plants that have enzymes with nickel as an active site. For this reason, the research literature on atomic calculations quotes the ground state configuration of nickel as [Ar] 3d9 4s1.[16]. The discovery of the large deposits in the Sudbury Basin, Canada in 1883, in Norilsk-Talnakh, Russia in 1920, and in the Merensky Reef, South Africa in 1924, made large-scale production of nickel possible.[45]. Nickel(I) complexes are uncommon, but one example is the tetrahedral complex NiBr(PPh3)3. Dehydration of NiCl2•6H2O gives the yellow anhydrous NiCl2. [65], The market price of nickel surged throughout 2006 and the early months of 2007; as of April 5, 2007, the metal was trading at US$52,300/tonne or $1.47/oz.
