It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature. Cadmium selenide is an inorganic compound with the formula Cd Se.It is a black to red-black solid that is classified as a II-VI semiconductor of the n-type.Much of the current research on this salt is … [109], World lead resources exceed two billion tons. [11], As a sensitive material to the infrared radiation, PbSe has unique and outstanding characteristics: it can detect IR radiation of wavelengths from 1.5 to 5.2 μm (mid-wave infrared window, abbreviated MWIR – in some special conditions it is possible to extend its response beyond 6 μm), it has a high detectivity at room temperature (uncooled performance), and due to its quantum nature, it also presents a very fast response, which makes this material an excellent candidate as detector of low cost high speed infrared imagers.[12]. Hydrogen selenide is a colorless gas that dissolves in water to make an acidic solution. There are many compounds which contains lead(Pb) like : NOTE: Plumbous = Lead(II) and Plumbic = Lead(IV) 1. [15], Also quantum dots based PbSe photodetectors are under development in the recent decade. Rev. Since then, PbSe has been commonly used as an infrared photodetector in multiple applications, from spectrometers for gas and flame detection to infrared fuzes for artillery ammunition or Passive Infrared Cueing systems (PICs). The rate of skin absorption is lower for inorganic lead. [145] Its status in Roman society was low as it was readily available[146] and cheap. [179] The share of the world's lead production by the Eastern Bloc increased from 10% to 30%, from 1950 to 1990, with the Soviet Union being the world's largest producer during the mid-1970s and the 1980s, and China starting major lead production in the late 20th century. Cesium Selenide is generally immediately available in most volumes. Provided below is a list of the chemical formulas of some common chemical compounds (along with their molecular weights). [110], Lead is added to copper alloys, such as brass and bronze, to improve machinability and for its lubricating qualities. A specific ion-selective electrode has been developed based on the ionophore S,S'-methylenebis (N,N-diisobutyldithiocarbamate). [85] For many organic compounds, a lead analog does not exist. N 3 − Azide. [175][176] The impact was significant: while a study conducted by the Centers for Disease Control and Prevention in the United States in 1976–1980 showed that 77.8% of the population had elevated blood lead levels, in 1991–1994, a study by the same institute showed the share of people with such high levels dropped to 2.2%. [124] Beginning circa 2000 BCE, the Phoenicians worked deposits in the Iberian peninsula; by 1600 BCE, lead mining existed in Cyprus, Greece, and Sardinia. [178], From 1960 to 1990, lead output in the Western Bloc grew by about 31%. This section will teach you how to find the correct ratio of ions, so that you can write a correct formula. Ga 3+ Gallium. Carbon (as coke or coal gas[p]) is added to the molten charge along with fluxing agents. The resulting bismuth dross can be skimmed off. [141][142] According to archaeological research, Roman lead pipes increased lead levels in tap water but such an effect was "unlikely to have been truly harmful". Several studies, mostly cross-sectional, found an association between increased lead exposure and decreased heart rate variability. [152][153] The largest production of lead occurred in South and East Asia, especially China and India, where lead mining grew rapidly. [104], Lead is classified as a chalcophile under the Goldschmidt classification, meaning it is generally found combined with sulfur. Further captures result in lead-206, lead-207, and lead-208. Much of the current research on this salt is focused on its nanoparticles. [204] It is used in scuba diving weight belts to counteract the diver's buoyancy. Pb[Fe(CN)6] … [172] Most European countries banned lead paint—commonly used because of its opacity and water resistance[173]—for interiors by 1930. MDL number MFCD00016273. sfn error: no target: CITEREFMeijaCoplenBerglundBrand2016 (, Centers for Disease Control and Prevention, a problem in areas with soft or acidic water, Restriction of Hazardous Substances Directive, University of California Nuclear Forensic Search Project, Committee on Evaluation of EPA Guidelines for Exposure to Naturally Occurring Radioactive Materials et al. Particulate control devices were installed in coal-fired power plants to capture lead emissions. [265], Ingestion of applied lead-based paint is the major source of exposure for children: [128] Lead coffins, cast in flat sand forms, with interchangeable motifs to suit the faith of the deceased were used in ancient Judea. The positive lead(II) ions are attracted to the negative electrode and are discharged to form molten lead. [153], In Europe, lead production began to increase in the 11th and 12th centuries, when it was again used for roofing and piping. [264] Dissolved carbon dioxide in the carried water may result in the formation of soluble lead bicarbonate; oxygenated water may similarly dissolve lead as lead(II) hydroxide. High performance infrared photodetectors up to 2.8 µm wavelength based on lead selenide colloidal quantum dots M.

The half-life found in the experiment was 1.9, Abundances in the source are listed relative to silicon rather than in per-particle notation. By association, lead was considered the father of all metals. Synonym: Lead (su)peroxide, Lead dioxide, Lead peroxide Linear Formula: PbO 2. [273], Lead can accumulate in soils, especially those with a high organic content, where it remains for hundreds to thousands of years. [89][k] With sodium metal, lead readily forms an equimolar alloy that reacts with alkyl halides to form organometallic compounds such as tetraethyllead. (b) The positive anode electrode reaction for the electrolysis of molten lead … [258], Lead exposure is a global issue since lead mining and smelting, and battery manufacturing/disposal/recycling, are common in many countries. Typically they are removed in a series of pyrometallurgical processes. The zinc solution can be separated from the lead, and the silver and gold retrieved. Molecular Formula. Example: The first box is the intersection between the “zinc” cation and the “chloride” anion, so you should write “ZnCl 2”, as shown. 2) Zn(CH3CO2)2. [125], Rome's territorial expansion in Europe and across the Mediterranean, and its development of mining, led to it becoming the greatest producer of lead during the classical era, with an estimated annual output peaking at 80,000 tonnes. Chemical Formula of Binary Ionic Compounds ... 22 lead(II) oxide PbO 47 lithium fluoride LiF 23 barium chloride BaCl 2 48 lithium iodide LiI 24 copper chloride CuCl 2 49 lithium hydride LiH 25 barium phosphide Ba 3 P 2 50 potassium oxide K 2 O “Aluminum” and “cesium” are commonly used alternative spellings for "aluminium" and "caesium that are used in the US. 1 0. The sum of all elements per 10. For example, a firm "...producing quality [lead] garden ornament from our studio in West London for over a century". Gaseous by-product of the coking process, containing. For a low-grade feed, all of the lead can be oxidized to a high-lead slag. High purity, submicron and nanopowder forms may be considered. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. Comments. [184] According to the International Resource Panel's Metal Stocks in Society report of 2010, the total amount of lead in use, stockpiled, discarded, or dissipated into the environment, on a global basis, is 8 kg per capita. Cubic crystal structure, density 8.10g/cm3. Lead; Lithium; Livermorium ☢ Lutetium; Magnesium ... (indium selenide). Formula. [277] Lead was banned for shot and sinkers in the United States in 2017,[278] although that ban was only effective for a month,[279] and a similar ban is being considered in the European Union. What Are U.S. Standards for Lead Levels? Many of them show defective fluorite structures in which some oxygen atoms are replaced by vacancies: PbO can be considered as having such a structure, with every alternate layer of oxygen atoms absent. [218] Molten lead has been used as a coolant for lead-cooled fast reactors. Zinc selenide is a chemical compound with a chemical formula of ZnSe. The lead in batteries undergoes no direct contact with humans, so there are fewer toxicity concerns. A (wet) finger can be dipped into molten lead without risk of a burning injury. [113], There is no consensus on the origin of the Proto-Germanic *lauda-. Its capacity to do so is much less because the Pb–Pb bond energy is over three and a half times lower than that of the C–C bond. Anions. Lead disulfide[72] and lead diselenide[73] are only stable at high pressures. Lead(II) sulfide (also spelled sulphide) is an inorganic compound with the formula Pb S. Galena is the principal ore and the most important compound of lead. It has a greater affinity for lead than calcium, with the result that lead chelate is formed by exchange and excreted in the urine, leaving behind harmless calcium. [102] At this point, the neutrons are arranged in complete shells in the atomic nucleus, and it becomes harder to energetically accommodate more of them. Optical constants of the noble metals, Phys. [286] Lead may still be found in harmful quantities in stoneware,[287] vinyl[288] (such as that used for tubing and the insulation of electrical cords), and Chinese brass. UO 2 2+ Uranyl . The sulfate ion is -2. Hydrometallurgical extraction, in which anodes of impure lead are immersed into an electrolyte and pure lead is deposited onto a cathode, is a technique that may have potential, but is not currently economical except in cases where electricity is very cheap. [116], Metallic lead beads dating back to 7000–6500 BCE have been found in Asia Minor and may represent the first example of metal smelting. [160] Concerns have been raised that lead bullets used for hunting can damage the environment. The top three producers of mined lead concentrate in that year were China, Australia, and the United States. [182], As of 2014, production of lead is increasing worldwide due to its use in lead–acid batteries. Soil can be contaminated through particulate accumulation from lead in pipes, lead paint, and residual emissions from leaded gasoline. [240] A 2009 Canadian–American study concluded that even at levels that are considered to pose little to no risk, lead may cause "adverse mental health outcomes". In the New World, lead production was recorded soon after the arrival of European settlers. [Se-2] InchI Identifier : InChI=1S/2Cs.Se/q2*+1;-2: InchI Key: KUBAIENASCDSDJ … It is a III-VI layered semiconductor. [155] In the European and Arabian traditions of alchemy, lead (symbol in the European tradition)[156] was considered an impure base metal which, by the separation, purification and balancing of its constituent essences, could be transformed to pure and incorruptible gold. Pb3P2 (Plumbous Phosphide) 5. [274] Fish uptake lead from both water and sediment;[275] bioaccumulation in the food chain poses a hazard to fish, birds, and sea mammals. rubidium sulfide and rubidium sulfate Write a formula from the name. The melt is treated in a reverberatory furnace with air, steam, and sulfur, which oxidizes the impurities except for silver, gold, and bismuth. The most well-characterized exceptions are Pb[CH(SiMe3)2]2 and Pb(η5-C5H5)2. [253] In pregnant women, high levels of exposure to lead may cause miscarriage. Use the Common Ion Table to find the formula and charge for the sulfate ion. [263] Hard water forms insoluble layers in the pipes whereas soft and acidic water dissolves the lead pipes. [267], Skin exposure may be significant for people working with organic lead compounds. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. [262], The use of lead for water pipes is a problem in areas with soft or acidic water. [188], Research on a cleaner, less energy-intensive lead extraction process continues; a major drawback is that either too much lead is lost as waste, or the alternatives result in a high sulfur content in the resulting lead metal. Compound Name Formula Search. H 3 O + Hydronium. [76][77][78] The same applies for lead(I), which can be found in such radical species. The white faces of women "came to represent their feminine virtue as Japanese women",[163] with lead commonly used in the whitener.[164]. The peak sensitivity depends on temperature and varies between 3.7–4.7 μm. Soluble in hot concentrated nitric acid and hydrochloric acid, and do not dissolve in water. PbS (Plumbous Sulphide) 6. Provied information about LEAD SELENIDE(Molecular Formula: PbSe, CAS Registry Number:12069-00-0 ) ,Boiling Point,Melting Point,Flash Point,Density,NMR Specturm,Molecular Structure,Risk Codes,Synthesis Route at guidechem The chemical formula for lead(IV) perchlorate is Pb(ClO4)4. N/A: Pubchem CID: 169244: IUPAC Name: dicesium selenium(2-) SMILES [Cs+].[Cs+]. Source(s): formula ionic compound formed calcium selenium: https://shortly.im/RFLx5. [119] Various civilizations of the Fertile Crescent used lead as a writing material, as currency, and as a construction material. For Lead (IV) sulfate we have a transition metal and a polyatomic ion. A similar fashion appeared in Japan in the 18th century with the emergence of the geishas, a practice that continued long into the 20th century. As 3− Arsenide. Wikidata Q56050531. On its own or mixed with cadmium sulfide, it is widely… [159] Despite being more expensive than iron, lead also became the chief material for making bullets for firearms. [193][195] This is a high-cost process and thus mostly reserved for refining bullion containing high percentages of impurities. [118] At that time lead had few (if any) applications due to its softness and dull appearance. [103] When the neutron flux subsides, these nuclei beta decay into stable isotopes of osmium, iridium, and platinum. [143][144] When lead poisoning did occur, victims were called "saturnine", dark and cynical, after the ghoulish father of the gods, Saturn. The chart below shows the calculated isotope pattern for the formula InSe with the most intense ion set to 100%. Ionic Compound Formula K sp. 2) CaSe. As 3− Arsenide. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions. It does so by binding to the sulfhydryl groups found on many enzymes,[249] or mimicking and displacing other metals which act as cofactors in many enzymatic reactions. Mechanisms of harm were better understood, lead blindness was documented, and the element was phased out of public use in the United States and Europe. [16], Except where otherwise noted, data are given for materials in their, Methods to manufacture PbSe infrared detectors, "High-temperature thermoelectric performance of heavily doped PbSe", "Study of the Thermoelectric Properties of Lead Selenide Doped with Boron, Gallium, Indium, or Thallium", National Pollutant Inventory - Lead and Lead Compounds Fact Sheet, https://en.wikipedia.org/w/index.php?title=Lead_selenide&oldid=996499833, Articles containing unverified chemical infoboxes, Articles with unsourced statements from February 2007, Creative Commons Attribution-ShareAlike License, This page was last edited on 26 December 2020, at 23:55. Atmospheric emissions of lead were at their peak during the Industrial Revolution, and the leaded gasoline period in the second half of the twentieth century. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions. It is only performed when metallic lead has undergone significant oxidation. [90] The oxidizing nature of many organolead compounds is usefully exploited: lead tetraacetate is an important laboratory reagent for oxidation in organic synthesis. mol −1: Melting point: 611 °C (1,132 °F; 884 K) [1] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). [266], Inhalation is the second major exposure pathway, affecting smokers and especially workers in lead-related occupations. Almost all inhaled lead is absorbed into the body; for ingestion, the rate is 20–70%, with children absorbing a higher percentage than adults. Copper(I) selenide, 99.95% trace metals basis Lead (II) sulfide has an cubic crystal structure with a unit cells forms by one anion surrounded by 6 cations (it can also be considered one cation surrounded by 6 anions). Lead selenide (PbSe) Hydrogen selenide, also known as hydroselenic acid, selenium hydride, or selane, is a chemical compound. This formula indicates that this compound is made up of twice as many sodium ions as sulfide ions. The lead monoxide is thereby reduced to metallic lead, in the midst of a slag rich in lead monoxide. Lead's toxicity has led to its phasing out for some uses. Alternatively, as the applied dry paint deteriorates, it peels, is pulverized into dust and then enters the body through hand-to-mouth contact or contaminated food, water, or alcohol. The names are found by finding the intersection between the cations and anions. The neutron flux involved may be on the order of 1022 neutrons per square centimeter per second. 1999, Gill & Libraries Board of South Australia 1974, Centers for Disease Control and Prevention 1997, United States Environmental Protection Agency 2010, California Department of Fish and Wildlife, National Council on Radiation Protection and Measurements 2004, United States Food and Drug Administration 2015, National Institute for Occupational Safety and Health, Occupational Safety and Health Administration, Agency for Toxic Substances and Disease Registry, Centers for Disease Control and Prevention 2015, United Nations Environment Programme 2010, Deltares & Netherlands Organisation for Applied Scientific Research 2016, Agency for Toxic Substances and Disease Registry 2017, United States Environmental Protection Agency 2000, United States Environmental Protection Agency 2005, "Lead: properties, history, and applications", "Information for the Community: Lead Toxicity", "Lead Toxicity. CAS : 12069-00-0 melting point : 1065 ° C Chinese name : lead selenide English title : lead selenide; lead selenide Notice:Each item can have many explanations from different angels. [280], Analytical methods for the determination of lead in the environment include spectrophotometry, X-ray fluorescence, atomic spectroscopy and electrochemical methods. a. lead (II): b. selenide: Name each ionic compound. [232] Lead tetraacetate and lead dioxide are used as oxidizing agents in organic chemistry. [115], The name of the chemical element is not related to the verb of the same spelling, which is derived from Proto-Germanic *laidijan- ("to lead"). [199], Of the sources of lead for recycling, lead–acid batteries are the most important; lead pipe, sheet, and cable sheathing are also significant. The Balearic slingers, used as mercenaries in Carthaginian and Roman armies, were famous for their shooting distance and accuracy. Make sure you check your work using the keys posted on www.mrrudolf.weebly.com !!! Diamond cubic structures with lattice parameters around the lattice parameter of silicon exists both in thin lead and tin films, and in massive lead and tin, freshly solidified in vacuum of ~5 x 10. PbSe. [288] White lead paint has been withdrawn from sale in industrialized countries, but specialized uses of other pigments such as yellow lead chromate remain. Properties. [284] A large drop in lead deposition occurred in the Netherlands after the 1993 national ban on use of lead shot for hunting and sport shooting: from 230 tonnes in 1990 to 47.5 tonnes in 1995. Early research works on the material as infrared detector were carried out during the 1930s and the first useful devices were processed by Germans, Americans and British during and just after World War II. Vacuum from lead and selenium direct response, or hydrogen reduction Lead … Titanium selenide is TiSe2. A further sesquioxide, Pb2O3, can be obtained at high pressure, along with several non-stoichiometric phases. [117] Britain was the leading producer, losing this status by the mid-19th century with the depletion of its mines and the development of lead mining in Germany, Spain, and the United States. In addition to being the main application for lead metal, lead-acid batteries are also the main consumer of lead compounds. On capturing another neutron, bismuth-209 becomes bismuth-210, and this beta decays to polonium-210, which alpha decays to lead-206. Chemical formulae provide a way to represent any chemical substance using the symbol of the elements present in it. The formula for zinc acetate is _____. Other articles where Cadmium selenide is discussed: cadmium: Compounds: One other compound of note, cadmium selenide (CdSe), is commonly precipitated by hydrogen selenide or alkaline selenides from solutions of cadmium salts. [82] In such anions, each atom is at a polyhedral vertex and contributes two electrons to each covalent bond along an edge from their sp3 hybrid orbitals, the other two being an external lone pair. [193][194] De-silvered lead is freed of bismuth by the Betterton–Kroll process, treating it with metallic calcium and magnesium. Contamination of soils and plants can allow lead to ascend the food chain affecting microorganisms and animals. PbSe was one of the first materials found to be sensitive to the infrared radiation used for military applications. [117], Lead tablets were commonly used as a material for letters. There are two main ways of doing this: a two-stage process involving roasting followed by blast furnace extraction, carried out in separate vessels; or a direct process in which the extraction of the concentrate occurs in a single vessel. Starting in the 13th century, lead was used to create stained glass. It is a compound that is brown in color and it is a crystalline solid. This article is about the metal. Drinking such water, over time, can cause health problems due to the toxicity of the dissolved lead. To balance we'll need two sulfate ions to give us a total -4. The sulfate ion is -2. [94] The abundance of lead in the Solar System since its formation 4.5 billion years ago has increased by about 0.75%. [180] Unlike the European communist countries, China was largely unindustrialized by the mid-20th century; in 2004, China surpassed Australia as the largest producer of lead. [157] During the period, lead was used increasingly for adulterating wine. They are unusual … [252], Symptoms of lead poisoning include nephropathy, colic-like abdominal pains, and possibly weakness in the fingers, wrists, or ankles. 1065 ° C melting point. It degrades the myelin sheaths of neurons, reduces their numbers, interferes with neurotransmission routes, and decreases neuronal growth.
