KnowraArsineArsineArsine (AsH₃) is a colorless, highly toxic, flammable gas in which one arsenic atom is bonded to three hydrogen atoms.BriefConnectArsenic–hydrogen bond: A chemical bond between arsenic and hydrogen atoms in arsenic hydrides. Three such bonds connect arsenic to hydrogen in each arsine molecule.Chemical vapor deposition: A process that forms solid films by chemical reactions of vapor-phase precursors. Arsine can supply arsenic during deposition of semiconductor films.Arsenic: A metalloid chemical element with atomic number 33. Arsenic is the central atom in arsine and determines its characteristic chemistry.Arsine poisoning: A severe toxic illness caused by inhaling arsine, which destroys red blood cells. This is the characteristic human consequence of acute arsine exposure.Molecular geometry: The three-dimensional arrangement of atoms in a molecule. Arsine has a trigonal-pyramidal shape, which follows from its bonding and lone electron pair.Gallium arsenide: A semiconductor compound of gallium and arsenic used in high-speed and optoelectronic devices. Arsine is a gaseous arsenic source used to grow gallium arsenide layers.Hydrogen: A chemical element with atomic number 1 and the lightest atoms. Hydrogen atoms form the three As–H bonds in arsine.Hemolysis: The rupture or destruction of red blood cells, releasing hemoglobin into surrounding fluid. Arsine poisoning causes intravascular hemolysis, which can damage the kidneys.Arsine decomposition: The breakdown of arsine into arsenic and hydrogen, promoted by heat or suitable surfaces. Decomposition can deposit arsenic and contributes to arsine’s behavior in fires and semiconductor processes.Indium arsenide: A semiconductor compound of indium and arsenic used in infrared and electronic devices. Arsine can provide arsenic for the epitaxial growth of indium arsenide.Show all 20Linked from 6 pagesBlood agentBroader topic: Its effects include hemolysis, a different route to impaired oxygen delivery.LewisiteCompared with: Both contain arsenic, but arsine chiefly causes hemolysis rather than Lewisite’s blistering injury.Pnictogen hydrideBroader topic: Its use in semiconductor fabrication illustrates the hazards of heavier hydrides.Arsenous acidCompared with: Arsine is a reduced, volatile arsenic compound, unlike oxygen-rich arsenous acid.DiphosphaneCompared with: Arsine is a heavier group-15 hydride counterpart to phosphine, rather than a P–P-linked hydride.Show all 6
