Precious metals
Precious metals are attractive metals of high monetary value that usually occur. Synthetically, precious metals tend to be less active than most compounds. Usually, they bend and have a lot of heat. Precious metals are generally important as money, but now they are considered as speculative and modern tools. There are ISO 4217 currency codes for gold, silver, platinum and palladium.
The most popular precious metals are gold and silver coins. Although both have modern goals, in art, beauty, and money, they are best known for their goals. Other important metals include the platinum group of metals: ruthenium, rhodium, palladium, osmium, iridium and platinum, the most commonly sold is platinum.
Rhodium plated
Rhodium is a synthetic material that has an image of Rh and an image of 45. The metal continues to be attractive, silvery white, strong, harmless to erosion, and synthetically inactive. It is a precious metal in the platinum group. It has only one common isotope, ¹⁰³ Rh.
Normally, rhodium is found in minerals, for example bowieite and rhodplumsite as free metals, which are combined with similar metals and rarely as synthetic compounds. It can be the most interesting and important jewelry.
Platinum
Platinum is a composite material with a PT frame and a 78 frame. It is a progressive metal that is incredibly strong, malleable, indestructible, precious, silver-white. Its name comes from the Spanish word for platinum, it means “little money”.
Platinum is one of the 10 timeless platinum compounds of the Time-Stopping Materials Chart. It has six common isotopes. It is one of the unique elements of the world with an economic value of around 5 μg/kg.
Gold
Gold is an element with the symbol Au (Latin: aurum) and nuclear number 79, making it one of the most common high nuclear number elements. It is an attractive yellow metal, with a slight red color, hard, strong, harmful and inefficient in its best composition. Synthetically, gold is the metal of change and part of the 11 selection.
Palladium
Palladium is a synthetic compound with nuclear number 46 in the Pd image. It is a rare and brilliant silver metal that was discovered by William Hyde Wollaston in 1803. He named it after the celestial Pallas, named after the moniker of the Greek goddess Athena, which she received when she killed Pallas. Palladium, platinum, rhodium, ruthenium, iridium and osmium make up elements called PGMs. Their properties are comparable, but palladium has the lowest melting point and is the most important of them.
Iridium
Iridium is an element with an element of Ir and an element of 77. Iridium is the second most dense metal (after osmium) with a density of 22.56 g/cm3 according to X-beam crystallography analysis, a hard, weak and shiny white metal in the platinum group .
Osmium
Osmium is an element with an Os image and a nuclear number of 76. In the platinum group, it is a continuous hard, brittle, blue-white metal found in compounds, mainly platinum minerals, such as small parts. Osmium is the hardest element of all time with a mass density of 22.59 g/cm3 (using X-beam crystallography). Manufacturers use their amalgams to create water-filled key tips, electrical contacts and other applications that require high strength in platinum, iridium and other platinum metals. The disposal of outgoing equipment is one of the most unusual.
Rhenium
Rhenium is a synthetic compound with nuclear number 75 and the symbol Re. In group 7 of the periodic table, it is a bright, dark, heavy metal, moving forward to the third. Rhenium is most likely a rare element outside of Earth with an expected abundance in the region of 1 part per billion (ppb). Rhenium has the third highest melting point of all elements at 5903 K and the second highest boiling point. Rhenium is similar to manganese and technetium and is often obtained as a side effect of the mining and refining of molybdenum and copper. Rhenium has different oxidation states in its compounds from -1 to +7.
Ruthenium
Ruthenium is a synthetic element with an element of Ru and an element of 44. An interesting continuous element has its place in the platinum group of the unchanging table. Like other metals in the platinum group, ruthenium does not react with many other synthetic compounds.
Most of the extracted ruthenium is used in electrical contacts and solid-film resistors that are resistant to corrosion. In platinum composites and as inspiration for science, there is a small application of ruthenium. Another use of ruthenium for bright photomasks is masking. Ruthenium is found mainly in minerals from the Ural Mountains in North and South America along with other metals of platinum. Similarly, pentlandite mined in Sudbury, Ontario and pyroxenite deposits in South Africa are small, but economically valuable.
Germanium
Germanium is an element with atomic number 32 and the symbol Ge. It belongs to a group of shiny, hard, gray carbon metalloids, similar to silicon and tin and its neighbors. Pure germanium is a semiconductor like silicon. Like silicone, germanium is very receptive to oxygen in nature and forms a structure.
Beryllium
Beryllium is a part of the element representing Be and nuclear number 4. It is a rare phenomenon in space that usually occurs due to the release of a large nuclear weapon that crashes into a large tree. Beryllium is ejected into the core of a star as it fuses and creates larger particles. A divalent component usually occurs only in combination with other mineral components. Gemstones containing beryllium are beryl (blue, emerald) and chrysoberyl. This is rust, the area is resistant to weakness and is soft on the bottom of the metal as a loose material.
Silver
Silver is an element with Ag image and atomic number 47. A soft transition, white, bright, it exhibits the highest electrical conductivity, light intensity and reflection of any metal. Outside the world, the metal is found in pure, free form (“local silver”), as a combination of gold and various metals, and minerals such as argentite and chlorargyrite. Most silver is made by refining copper, gold, lead, and zinc.
Indium
Indium is a synthetic metal with atomic number 49. Indium is the softest metal and is not considered an iron salt. Silver metals such as Tin (Sn). The universe continues to contain 0.21 particles from outer Earth per million.
The melting point of indium is higher than that of sodium and gallium, but lower than that of lithium and tin. Indium is similar to gallium and thallium and, in terms of its properties, often falls between the two.
Indium was discovered by spectroscopic methods by Ferdinand Reich and Hieronymous Theodor Richter in 1863. They named it in their line for the indigo blue line. The following year, Indium was separated.
Gallium
Gallium is a synthetic element with the atomic number Ga and nuclear number 31. Gallium is slightly blue in its solid state; However, it becomes bright white in its wet state. Gallium is soft enough to cut, but if too much force is applied, gallium can break in an instant.
It appears on the periodic table of 13 elements and has similarities with various metals such as lead, aluminum, indium and thallium. Gallium does not occur in nature as a free element, but follows a combination with zinc minerals and bauxite as gallium(III) compounds.
Essential gallium is liquid at temperatures above 29.76 °C (85.57 °F) (above room temperature, but below room temperature of 37 °C (99 °F), so that iron the body dissolves into a person).
Tellurium
Tellurium is an element with the atomic number Te and nuclear number 52. It is a rare, less harmful, small, silvery-white metalloid. Tellurium combines with selenium and sulfur, three of which are chalcogen. It is found in some places such as foundation stones and landscaping.
Tellurium is more common in the global atmosphere than on Earth. Its extreme extraterrestrial samples, similar to those of platinum, are due to some extent to the development of unstable hydrides that caused tellurium to be lost as a gas during the hot nebular formation of the Earth. , and part of the low tellurium pathway. The energy for oxygen is mainly associated with other chalcophiles and minerals that sink in between.
Bismuth
Bismuth is a compound that has the image of Bi and nuclear number 83. It is a pentavalent metal that continues to have products such as its hot plant arsenic and antimony and one of the pnictogens. Bismuth is the most common primary mineral, although the sulfide and oxide are used to produce important commercial metals.
This free application is as high as 86% lead. When fresh, it is a malleable metal with a bright white tone, but surface oxidation can give it a pinkish hue. Bismuth is a commonly used diamagnetic material, having among metals one of the best conductivity values.
Mercury
Mercury is an element that contains Hg in Figure 80. It is commonly called mercury and was formerly called hydrargyrum. The heavy, shiny d-block component, mercury is the main liquid substance under high temperature and pressure conditions; Another element that is liquid under these conditions is the halogen bromine, although metals such as cesium, gallium and rubidium are softer at higher temperatures.
Mercury is found primarily in the form of cinnabar (mercury sulfide) in stores around the world. By crushing common cinnabar or artificial mercury sulfide, a red tint of vermilion is obtained.
