Terlinguaite
Terlinguaite is the naturally occurring mineral with formula . It is formed by the weathering of other mercury (element), mercury-containing minerals. It was discovered in 1900 in the Terlingua, Texas, Terlingua District of Brewster County, Texas, for which it is named. Its color is yellow, greenish yellow, brown, or olive green.

Mercury Polycations
Mercury polycations are polyatomic cations that contain only mercury (element), mercury atoms. The best known example is the ion, found in mercury(I) (mercurous) compounds. The existence of the metal–metal bond in Hg(I) compounds was established using X-ray spectroscopy, X-ray studies in 1927 and Raman spectroscopy in 1934 making it one of the earliest, if not the first, metal–metal covalent bonds to be characterised. Other mercury polycations are the linear and ions, and the triangular ion and a number of chain and layer polycations. Mercury(I) The best known polycation of mercury is , in which mercury has a formal oxidation state of +1. The ion was perhaps the first metal-metal bonded species confirmed. The presence of the ion in solution was shown by Ogg in 1898. In 1900, Baker showed the presence of HgCl dimers in the vapour phase. The presence of units in the solid state was first determined in 1926 using X-ray diffraction. The presence of the metal-metal bond in ...

Terlingua
Terlingua ( ) is a mining district and census-designated place (CDP) in southwestern Brewster County, Texas, Brewster County, Texas, United States. It is located near the Rio Grande and the villages of Lajitas, Texas, Lajitas and Study Butte, Texas, as well as the Mexico, Mexican state of Chihuahua (state), Chihuahua. The discovery of cinnabar, from which the metal mercury (element), mercury is extracted, in the mid-1880s brought miners to the area, creating a city of 2,000 people. The only remnants of the mining days are a ghost town of the Howard Perry-owned Chisos Mining Company and several nearby capped and abandoned mines: the California Hill, the Rainbow, the 248, and the Study Butte mines. The mineral terlinguaite was first found in the vicinity of California Hill. The population of Terlingua as of 2020 was 78. History According to the historian Kenneth Baxter Ragsdale, "Facts concerning the discovery of cinnabar in the Terlingua area are so shrouded in legend and ...

Brewster County
Brewster County is a county located in the U.S. state of Texas. It is in West Texas and its county seat (and only city) is Alpine. It is one of the nine counties that comprise the Trans-Pecos region, and borders Mexico. Brewster County is the largest county by area in the state - at it is over three times the size of the state of Delaware, and more than bigger than Connecticut. As of the 2020 census, the population was 9,546. The county is named for Colonel Henry Percy Brewster, a Secretary of War for the Republic of Texas. History Native Americans Paleo-Indian hunter-gatherers existed in the region at least 9000 years ago. Mescalaro Apaches emerged later and conducted raids that discouraged settlers. Between 1779 and 1787, Col. Juan de Ugalde drove the Mescalaros back north across the Rio Grande and into the Chisos Mountains. The three leading Mescalero chiefs, Patula Grande, Quemado, and Zapato Tuerto, agreed in March 1789 to submit to Spanish rule. Comanche raidi ...

Monoclinic
In crystallography, the monoclinic crystal system is one of the seven crystal systems. A crystal system is described by three Vector (geometric), vectors. In the monoclinic system, the crystal is described by vectors of unequal lengths, as in the orthorhombic system. They form a parallelogram prism (geometry), prism. Hence two pairs of vectors are perpendicular (meet at right angles), while the third pair makes an angle other than 90°. Bravais lattices Two monoclinic Bravais lattices exist: the primitive monoclinic and the base-centered monoclinic. For the base-centered monoclinic lattice, the primitive cell has the shape of an oblique rhombic prism;See , row mC, column Primitive, where the cell parameters are given as a1 = a2, α = β it can be constructed because the two-dimensional centered rectangular base layer can also be described with primitive rhombic axes. The length a of the primitive cell below equals \frac \sqrt of the conventional cell above. Crystal class ...

Ångström
The angstrom (; ) is a unit of length equal to m; that is, one ten-billionth of a metre, a hundred-millionth of a centimetre, 0.1 nanometre, or 100 picometres. The unit is named after the Swedish physicist Anders Jonas Ã…ngström (1814–1874). It was originally spelled with Swedish letters, as Ã…ngström and later as Ã¥ngström (). The latter spelling is still listed in some dictionaries, but is now rare in English texts. Some popular US dictionaries list only the spelling ''angstrom''. The unit's symbol is Ã…, which is a letter of the Swedish alphabet, regardless of how the unit is spelled. However, "A" or "A.U." may be used in less formal contexts or typographically limited media. The angstrom is often used in the natural sciences and technology to express sizes of atoms, molecules, microscopic biological structures, and lengths of chemical bonds, arrangement of atoms in crystals, wavelengths of electromagnetic radiation, and dimensions of integrated circuit part ...

Mercury (element)
Mercury is a chemical element; it has Symbol (chemistry), symbol Hg and atomic number 80. It is commonly known as quicksilver. A Heavy metal element, heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Exposure to mercury and mercury-containing organic compounds is toxic to the nervous system, immune system and kidneys of humans and other animals; mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury) either directly or through mechanisms of biomagnification.

Chlorine
Chlorine is a chemical element; it has Symbol (chemistry), symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidizing agent, oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity on the revised Electronegativity#Pauling electronegativity, Pauling scale, behind only oxygen and fluorine. Chlorine played an important role in the experiments conducted by medieval Alchemy, alchemists, which commonly involved the heating of chloride Salt (chemistry), salts like ammonium chloride (sal ammoniac) and sodium chloride (common salt), producing various chemical substances containing chlorine such as hydrogen chloride, mercury(II) chloride (corrosive sublimate), and . However, the nature of fre ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
