[123], Because silver was extensively used as a decorative material and an exchange medium, lead deposits came to be worked in Asia Minor from 3000 BCE; later, lead deposits were developed in the Aegean and Laurion. [110], Lead is added to copper alloys, such as brass and bronze, to improve machinability and for its lubricating qualities. [124] Beginning circa 2000 BCE, the Phoenicians worked deposits in the Iberian peninsula; by 1600 BCE, lead mining existed in Cyprus, Greece, and Sardinia. [106] Many lead minerals are relatively light and, over the course of the Earth's history, have remained in the crust instead of sinking deeper into the Earth's interior. [261] Fruit and vegetables can be contaminated by high levels of lead in the soils they were grown in. Arsenic, tin, antimony, silver, gold, copper, and bismuth are common impurities in lead minerals. N 3 − Azide. [92] The amount of lead in the universe is slowly increasing[93] as most heavier atoms (all of which are unstable) gradually decay to lead. [295], Research has been conducted on how to remove lead from biosystems by biological means: Fish bones are being researched for their ability to bioremediate lead in contaminated soil. Make sure you check your work using the keys posted on !!! [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. 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). In the New World, lead production was recorded soon after the arrival of European settlers.

(Note that incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) The resulting concentrate, which has a lead content of 30–80% by mass (regularly 50–60%),[187] is then turned into (impure) lead metal. Formulas and Nomenclature of Ionic and Covalent Compounds. 0 0. [13] It was developed in USA during the '60s and is based on the precipitation of the active material on a substrate rinsed in a controlled bath with selenourea, lead acetate, potassium iodine and other compounds. Pb(NO3)2 (Plumbous Nitrate) 4. [118] At that time lead had few (if any) applications due to its softness and dull appearance. It remains the main material for bullets, alloyed with other metals as hardeners. [83], Lead can form multiply-bonded chains, a property it shares with its lighter homologs in the carbon group. Room temperature. In low concentrations, as well as acting as a lubricant, the globules hinder the formation of swarf as the alloy is worked, thereby improving machinability. What is the correct chemical formula of calcium selenide? 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. N/A: Pubchem CID: 169244: IUPAC Name: dicesium selenium(2-) SMILES [Cs+].[Cs+]. [202], Lead has been used for bullets since their invention in the Middle Ages. [248] The primary cause of its toxicity is its predilection for interfering with the proper functioning of enzymes. [110] The top three producers of refined lead were China, the United States, and India.

This formula indicates that this compound is made up of twice as many sodium ions as sulfide ions. 1) Ti(CN)4 2) TiC4N4 3) Sn(CN)4 4) SnC4N4 5) Sn(CN)2. [268], Treatment for lead poisoning normally involves the administration of dimercaprol and succimer. We have step-by-step solutions for your textbooks written by Bartleby experts! [238], Lead has no confirmed biological role, and there is no confirmed safe level of lead exposure. [255] Early childhood exposure has been linked with an increased risk of sleep disturbances and excessive daytime drowsiness in later childhood. Oxidized contaminants float to the top of the melt and are skimmed off. [112] The Old English word is derived from the hypothetical reconstructed Proto-Germanic *lauda- ("lead"). Some primary production plants now supplement their operations with scrap lead, and this trend is likely to increase in the future. A further sesquioxide, Pb2O3, can be obtained at high pressure, along with several non-stoichiometric phases. [citation needed], Single crystal nanorods and polycrystalline nanotubes of lead selenide have been synthesized via controlled organism membranes. Copper(i)selenide. [74], Some lead compounds exist in formal oxidation states other than +4 or +2. [94] The abundance of lead in the Solar System since its formation 4.5 billion years ago has increased by about 0.75%. [128] Lead coffins, cast in flat sand forms, with interchangeable motifs to suit the faith of the deceased were used in ancient Judea. It may be formed by direct reaction between its constituent elements, lead and selenium. By mimicking calcium, lead can cross the blood–brain barrier. [145] Its status in Roman society was low as it was readily available[146] and cheap. [92][l] This figure is two and a half times higher than that of platinum, eight times more than mercury, and seventeen times more than gold. It is yellow to red in appearance with a melting point of >1,100°C, a density of 5.42 g/cc, and a vapor pressure of 10-4 Torr at 660°C. References. [265], Ingestion of applied lead-based paint is the major source of exposure for children: [138][139][n] Other researchers have criticized such claims, pointing out, for instance, that not all abdominal pain is caused by lead poisoning. 0 0. [199], Of the sources of lead for recycling, lead–acid batteries are the most important; lead pipe, sheet, and cable sheathing are also significant. UNII-44P3QN57K9. Formula: PbSe2.

[244] A small amount of lead (1%) is stored in bones; the rest is excreted in urine and feces within a few weeks of exposure. [198] The Isasmelt process is a more recent smelting method that may act as an extension to primary production; battery paste from spent lead–acid batteries (containing lead sulfate and lead oxides) has its sulfate removed by treating it with alkali, and is then treated in a coal-fueled furnace in the presence of oxygen, which yields impure lead, with antimony the most common impurity. Name. Molecular formula : CAS : nature : gray or dark gray crystalline powder. The formula for magnesium selenide is MgSe. The word *ɸloud-io- is thought to be the origin of Proto-Germanic *bliwa- (which also means "lead"), from which stemmed the German Blei. [293] Lead is released to the wildlife in shooting places and a number of lead management practices, such as stewardship of the environment and reduced public scrutiny, have been developed to counter the lead contamination. N 3− Nitride. Molecular Formula. Name. The ratio of Pb^(4+) and O^(2-) ios is 1:2 and hence the formula is PbO_2. [181] As was the case during European industrialization, lead has had a negative effect on health in China. Lead; Lithium; Livermorium ☢ Lutetium; Magnesium ... (indium selenide). For a low-grade feed, all of the lead can be oxidized to a high-lead slag. Lead sulfide is a semiconductor, a photoconductor, and an extremely sensitive infrared radiation detector. [183] There are two major categories of production: primary from mined ores, and secondary from scrap. 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. The white faces of women "came to represent their feminine virtue as Japanese women",[163] with lead commonly used in the whitener.[164].

Other names Cadmium(2+) selenide Cadmium(II) selenide, cadmoselite. This metal was by far the most used material in classical antiquity, and it is appropriate to refer to the (Roman) Lead Age. It degrades the myelin sheaths of neurons, reduces their numbers, interferes with neurotransmission routes, and decreases neuronal growth. [270], The extraction, production, use, and disposal of lead and its products have caused significant contamination of the Earth's soils and waters. 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). The latter has become the most common route, though the former is still significant. [119] Various civilizations of the Fertile Crescent used lead as a writing material, as currency, and as a construction material. [171], In the 1970s, the United States and Western European countries introduced legislation to reduce lead air pollution. Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. [262], The use of lead for water pipes is a problem in areas with soft or acidic water. Zn 2+ Zinc. [266], Inhalation is the second major exposure pathway, affecting smokers and especially workers in lead-related occupations. 1314-87-0 3D model . [148] To add to the confusion, lead bore a close relation to antimony: both elements commonly occur as sulfides (galena and stibnite), often together. (Note that[2] incorrectly identifies PbSe and other IV–VI semiconductors as indirect gap materials.) In Roman times, lead sling bullets were amply used, and were effective at a distance of between 100 and 150 meters. Global reserves—resources that are economically feasible to extract—totaled 88 million tons in 2016, of which Australia had 35 million, China 17 million, and Russia 6.4 million. [244], Lead can cause severe damage to the brain and kidneys and, ultimately, death. Its chemical formula is H 2 Se. This method has an intrinsic advantage compared with the CBD method, which is the compatibility with preprocessed substrates, like silicon CMOS-technology wafers, and the possibility of processing complex detectors, such as the focal plane arrays for imagers. White tin effectively has a structure intermediate between the regular tetrahedral structure of gray tin, and the regular face centered cubic structure of lead, consistent with the general trend of increasing metallic character going down any representative group. [95] The solar system abundances table shows that lead, despite its relatively high atomic number, is more prevalent than most other elements with atomic numbers greater than 40. Most lead ores contain a low percentage of lead (rich ores have a typical content of 3–8%) which must be concentrated for extraction. One hypothesis suggests it is derived from Proto-Indo-European *lAudh- ("lead"; capitalization of the vowel is equivalent to the macron). 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. [233][234] It can be used to treat candle wicks to ensure a longer, more even burn. Formula. [188], First, the sulfide concentrate is roasted in air to oxidize the lead sulfide:[189], As the original concentrate was not pure lead sulfide, roasting yields not only the desired lead(II) oxide, but a mixture of oxides, sulfates, and silicates of lead and of the other metals contained in the ore.[190] This impure lead oxide is reduced in a coke-fired blast furnace to the (again, impure) metal:[191], Impurities are mostly arsenic, antimony, bismuth, zinc, copper, silver, and gold. PbSe was one of the first materials found to be sensitive to the infrared radiation used for military applications. [177] The main product made of lead by the end of the 20th century was the lead–acid battery. H + Hydrogen . [225] Its use in solder for electronics is also being phased out by some countries to reduce the amount of environmentally hazardous waste. [104], Lead is classified as a chalcophile under the Goldschmidt classification, meaning it is generally found combined with sulfur. [256] High blood levels are associated with delayed puberty in girls. [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". [197], Smelting, which is an essential part of the primary production, is often skipped during secondary production. [166] In Africa, lead mining and smelting were known in the Benue Trough[167] and the lower Congo Basin, where lead was used for trade with Europeans, and as a currency by the 17th century,[168] well before the scramble for Africa. [84] With carbon, lead forms organolead compounds similar to, but generally less stable than, typical organic compounds[85] (due to the Pb–C bond being rather weak). [281] An important biomarker assay for lead poisoning is δ-aminolevulinic acid levels in plasma, serum, and urine. [193][195] This is a high-cost process and thus mostly reserved for refining bullion containing high percentages of impurities. Chemical Formula Writing Worksheet Solutions Write chemical formulas for the compounds in each box. [99] This occurs in environments with a high neutron density, such as a supernova or the merger of two neutron stars. [113] According to linguistic theory, this word bore descendants in multiple Germanic languages of exactly the same meaning. [152][153] The largest production of lead occurred in South and East Asia, especially China and India, where lead mining grew rapidly. [215][216] Lead is an established shielding material from radiation in nuclear science and in X-ray rooms[217] due to its denseness and high attenuation coefficient. No elements with odd atomic numbers have more than two stable isotopes; even-numbered elements have multiple stable isotopes, with tin (element 50) having the highest number of isotopes of all elements, ten. [85] For many organic compounds, a lead analog does not exist. [111], The modern English word "lead" is of Germanic origin; it comes from the Middle English leed and Old English lēad (with the macron above the "e" signifying that the vowel sound of that letter is long). Small blood pressure increases, particularly in middle-aged and older people, may be apparent and can cause anemia. CBD method has been extensively used during last decades and is still used for processing PbSe infrared detectors. [185], The primary and secondary lead production processes are similar. [237] Lead-based semiconductors such as lead telluride and lead selenide are used in photovoltaic cells and infrared detectors. Name.

The neutron flux involved may be on the order of 1022 neutrons per square centimeter per second. [208][209] Lead is still used in statues and sculptures,[r] including for armatures. [186] The process is similar to that of primary production in either a blast furnace or a rotary furnace, with the essential difference being the greater variability of yields: blast furnaces produce hard lead (10% antimony) while reverberatory and rotary kiln furnaces produced semisoft lead (3–4% antimony). [260] Seawater products can contain lead if affected by nearby industrial waters. [109], World lead resources exceed two billion tons. [89][k] With sodium metal, lead readily forms an equimolar alloy that reacts with alkyl halides to form organometallic compounds such as tetraethyllead. Lead-based coloring agents are used in ceramic glazes and glass, especially for red and yellow shades.

It does not require cooling, but performs better at lower temperatures. Further captures result in lead-206, lead-207, and lead-208. To balance we'll need two sulfate ions to give us a total -4. This is a reduction reaction because the lead ions gain electrons. [173] Stripping old paint by sanding produces dust which can be inhaled. Textbook solution for Chemistry: An Atoms First Approach 2nd Edition Steven S. Zumdahl Chapter 3 Problem 119E. If you want grasp the item comprehensively,please see below "more details data". Formula. [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. rubidium sulfide and rubidium sulfate Write a formula from the name. Once electrical potential is applied, impure lead at the anode dissolves and plates onto the cathode, leaving the majority of the impurities in solution. Lead selenide is a thermoelectric material. [171], Further evidence of the threat that lead posed to humans was discovered in the late 19th and early 20th centuries. What Are U.S. Standards for Lead Levels? Like their predecessors, the Romans obtained lead mostly as a by-product of silver smelting. Lead's toxicity has led to its phasing out for some uses. Goose. Scrap lead from the building trade is usually fairly clean and is re-melted without the need for smelting, though refining is sometimes needed. Compound Name Formula Search. [182], As of 2014, production of lead is increasing worldwide due to its use in lead–acid batteries. 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. [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.
