Query: What does the symbol for silver Ag come from?
Silver is a chemical element with symbol Ag (from the Latin "", derived from the Proto-Indo-European "h₂erǵ": "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver or hydrargyrum ( < Greek "" "water" and "" "silver"). A heavy, silvery d-block element, mercury is the only metal that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine, though metals such as caesium, francium, gallium, and rubidium melt just above room temperature. With a freezing point of −38.83 °C and boiling point of 356.73 °C, mercury has one of the narrowest ranges of its liquid state of any metal.
Palladium is a chemical element with the chemical symbol Pd and an atomic number of 46. It is a rare and lustrous silvery-white metal discovered in 1803 by William Hyde Wollaston. He named it after the asteroid Pallas, which was itself named after the epithet of the Greek goddess Athena, acquired by her when she slew Pallas. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them.
The cardinal red university color symbolizes love, the Holy Spirit, martyrdom, loyalty, and victory. The silver chevron comes from the first letter 'ㅅ' of 서강 (Sogang), representing the intellectual spirit of Sogang and an ivory tower. The "IHS" comes from the first letters of the Greek name for Jesus and is also found on the seal of the Society of Jesus, the Catholic religious order that founded the University. The medieval crown stands for the Virgin and Trinity, symbolizing wisdom. Sogang University also has a famous slogan which is: Be as Proud of Sogang as Sogang is Proud of You. (그대 서강의 자랑이듯, 서강 그대의 자랑이어라)
Hg is the chemical symbol of Mercury.
The combination of metals was a basic technique. Essentially, there is no such thing as 24 carat gold jewelry. Massive gold is the most malleable metal. It is almost like wax. In order to have jewelry that can pass the test of time and gravity, the Etruscans had to combine their gold with other metals.
The Coinage Act of 1873 ended production of the standard silver dollar and authorized creation of the Trade dollar, thus concluding the Seated Liberty dollar series. The Trade dollar was slightly heavier than the standard dollar and was intended for use in payments in silver to merchants in China. Although not meant for use in the United States, a last-minute rider gave it legal tender status there up to $5. When silver prices plummeted in the mid-1870s, millions appeared in circulation, at first in the West and then throughout the United States, causing problems in commerce when banks insisted on the $5 legal tender limit. Other abuses followed, such as purchase by companies for bullion value (by then about $0.80) for use in pay packets. Workers had little option but to accept them as dollars. In response to complaints, Congress ended any status as legal tender in 1876, halted production of the Trade dollar (except for collectors) in 1878, and agreed to redeem any which had not been chopmarked in 1887.
The dollar coin is a United States coin worth one United States dollar. It is the second largest U.S. coin currently minted for circulation in terms of physical size, with a diameter of 1.043 inches (26.5 mm) and a thickness of .079 inches (2 mm), coming second to the half dollar. Dollar coins have been minted in the United States in gold, silver, and base metal versions. Dollar coins were first minted in the United States in 1794. The term silver dollar is often used for any large white metal coin issued by the United States with a face value of one dollar, whether or not it contains some of that metal. While true gold dollars are no longer minted, the Sacagawea and Presidential dollars are sometimes referred to as golden dollars due to their color.
The Bronze Age was the period in human cultural development when the most advanced metalworking (at least in systematic and widespread use) included techniques for smelting copper and tin from naturally-occurring outcroppings of copper ores, and then combining those ores to cast bronze. These naturally-occurring ores typically included arsenic as a common impurity. Copper/tin ores are rare, as reflected in the fact that there were no tin bronzes in western Asia before 3000 BC. In some parts of the world, a Copper Age follows the Neolithic and precedes the Bronze Age.
Oganesson is a synthetic chemical element with symbol Og and atomic number 118. It was first synthesized in 2002 at the Joint Institute for Nuclear Research (JINR) in Dubna, near Moscow in Russia, by a joint team of Russian and American scientists. In December 2015, it was recognized as one of four new elements by the Joint Working Party of the international scientific bodies IUPAC and IUPAP. It was formally named on 28 November 2016. The name is in line with the tradition of honoring a scientist, in this case the nuclear physicist Yuri Oganessian, who has played a leading role in the discovery of the heaviest elements in the periodic table. It is one of only two elements named after a person who was alive at the time of naming, the other being seaborgium; it is also the only element whose namesake is alive today.
The six leaves symbolize the merger of the six former communities into the greater community. They are appletree leaves (which is not mentioned in the German blazon), referring to a variety of apple named after the centre of Ausbach, the "Ausbacher Roter", which is often still found growing on orchard meadows. The tinctures silver and red come from the arms borne by the Lords of Mansbach, Electorate of Hesse and the community of Ransbach. The gyronny parting – the pattern of parting lines radiating from the escutcheon’s centre – likewise comes from the von Mansbach family’s arms.Sonnenuhrgebäude (Renaissance castle, fortified.
Platinum is a chemical element with symbol Pt and atomic number 78.
After the retreat of the Kuomintang to Taiwan, the silver yuan remained the de jure legal currency of account of the Republic of China, although only Taiwan dollars issued by the Bank of Taiwan were circulating in areas controlled by the ROC. After a currency reform in 1949 created the New Taiwan dollar, the statutory exchange rate was set at 1 silver yuan = NT$3.
The złoty (golden) is a traditional Polish currency unit dating back to the late Middle Ages. Initially, in the 14th and 15th centuries, the name was used for all kinds of foreign gold coins used in Poland, most notably Venetian and Hungarian ducats, (however, in provinces Volyn & Galych the name for them were the "золотий"(zolotyii) - golden). One złoty at the very beginning of their introduction cost 12–14 groszy; however, grosz had less and less silver as time passed. In 1496 the Sejm approved the creation of a national currency, the złoty, and its value was set at 30 groszy, a coin minted since 1347 and modelled on the Prague groschen, and a "ducat" ("florin"), whose value was złoty. The 1:30 proportion stayed ( of a kopa), but the grosz became cheaper and cheaper, because the proportion of silver in the coin alloy diminished over time. In the beginning of the 16th century, 1 złoty was worth 32 groszy; by the middle of the same century it was 50 groszy; by the reign of Sigismund III Vasa 1 złoty was worth 90 groszy, while a ducat was worth 180 groszy.
Platinum is a chemical element with the chemical symbol Pt and an atomic number of 78.
Lanthanum is a chemical element with the symbol La and atomic number 57. It is the first element in the lanthanide series. It is a soft, ductile, silvery-white metal that tarnishes rapidly when exposed to air and is soft enough to be cut with a knife. It is the eponym of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the periodic table, of which lanthanum is the first and the prototype. It is also sometimes considered the first element of the 6th-period transition metals and is traditionally counted among the rare earth elements. The usual oxidation state is +3. Lanthanum has no biological role in humans but is essential to some bacteria. It is not particularly toxic to humans but does show some antimicrobial activity.
He applied for another patent on an alloy he called stainless steel, now known as martensitic stainless steel. The Patent Office rejected his application saying that it was not a new alloy. Haynes conceded their point, but submitted a second application and supplied a sample showing the stainlessness of his alloy when created using his exact proportions of metals, and it was granted. At the urging of his wife, he created the first set of stainless steel silverware for her personal use. The first piece of stainless steel was forged by Homer Dan Farmer in Haynes laboratory. It was a large meat knife and was donated to the Haynes Museum by the family of Dan Heflin, grandson of Homer Dan Farmer. In later years he claimed to have created stainless steel because she did not enjoy polishing their silver tableware. British metallurgist Harry Brearley independently produced an identical alloy around the same time and applied for an American patent and found that one already existed. Brearley had also created other innovations for the metal, but they were of little value without the stainless steel patent. He sought out Haynes and the two decided to pool their findings in a single company to produce the alloy. Haynes sold his stainless steel patent in 1918 to the American Stainless Steel Company, a company Brearley had created with the assistance of investors in Pennsylvania. In exchange he and his estate received royalties on its production until the patent expired in 1930. The stock he received as payment allowed him to gain a seat among the company's board of directors and he installed his son, March, to represent him. The income from the transaction led Haynes to begin the accumulation of a large fortune.
The złoty (pronounced ; sign: zł; code: PLN), which is the masculine form of the Polish adjective 'golden', is the currency of Poland. The modern złoty is subdivided into 100 groszy (singular: "grosz"; alternative plural form: "grosze"). The recognised English form of the word is "zloty", plural zloty or zlote. The currency sign, zł, is composed of the Polish lower-case letters "z" and "ł" (Unicode: & ).
Hassium is a synthetic chemical element with symbol Hs and atomic number 108. It is named after the German state of Hesse. It is a synthetic element and radioactive; the most stable known isotope, Hs, has a half-life of approximately 10 seconds.
The chalcogens () are the chemical elements in group 16 of the periodic table. This group is also known as the oxygen family. It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive element polonium (Po). The chemically uncharacterized synthetic element livermorium (Lv) is predicted to be a chalcogen as well. Often, oxygen is treated separately from the other chalcogens, sometimes even excluded from the scope of the term "chalcogen" altogether, due to its very different chemical behavior from sulfur, selenium, tellurium, and polonium. The word "chalcogen" is derived from a combination of the Greek word "khalkόs" (χαλκός) principally meaning copper (the term was also used for bronze/brass, any metal in the poetic sense, ore or coin), and the Latinised Greek word "genēs", meaning "born" or "produced".
Compared to other metals, gold is malleable, ductile, rare, and it is the only solid metallic element with a yellow color. It may easily be melted, fused, and cast without the problems of oxides and gas that are problematic with other metals such as bronzes, for example. It is fairly easy to "pressure weld", wherein similarly to clay two small pieces may be pounded together to make one larger piece. Gold is classified as a noble metal—because it does not react with most elements. It usually is found in its native form, lasting indefinitely without oxidization and tarnishing.
Hg is the modern chemical symbol for mercury. It comes from "hydrargyrum", a Latinized form of the Greek word Ύδραργυρος ("hydrargyros"), which is a compound word meaning "water-silver" (hydr- = water, argyros = silver) — since it is liquid like water and shiny like silver. The element was named after the Roman god Mercury, known for speed and mobility. It is associated with the planet Mercury; the astrological symbol for the planet is also one of the alchemical symbols for the metal. Mercury is the only metal for which the alchemical planetary name became the common name.
Silver is a metallic chemical element with the chemical symbol Ag (, from the Indo-European root "*arg-" for "grey" or "shining") and atomic number 47. A soft, white, lustrous transition metal, it has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. The metal occurs naturally in its pure, free form (native silver), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
In addition to its original intended use as a country code, the .ag domain has been marketed for use for agriculture-related sites, and for sites referencing the atomic symbol for silver, Ag. It also has a potential use for other domain hacks for English words that end in -ag. The Heritage Foundation uses .ag for URL shortening (herit.ag).
A code used by some manufacturers is "AG" (alkaline) or "SG" (silver) followed by a number, where 1 equates to standard 621, 2 to 726, 3 to 736, 4 to 626, 5 to 754, 6 to 920 or 921, 7 to 926 or 927, 8 to 1120 or 1121, 9 to 936, 10 to 1130 or 1131, 11 to 721, 12 to 1142, and 13 to 1154. To those familiar with the chemical symbol for silver, Ag, this may suggest incorrectly that AG cells are silver.In addition to disposable (single use) button cells, rechargeable batteries in many of the same sizes are available, with lower capacity than disposable cells. Disposable and rechargeable batteries are manufactured to fit into a holder or with solder tags for permanent connection. In equipment with a battery holder, disposable or rechargeable batteries may be used, if the voltage is compatible.
