Qhov sib txawv tseem ceeb ntawm arsenic thiab arsine yog tias arsenic yog cov tshuaj lom neeg, whereas arsine yog cov tshuaj lom neeg.
Arsine yog cov tshuaj lom neeg muaj roj uas tshwm sim los ntawm kev sib xyaw ntawm arsenic thiab hydrogen atoms. Arsenic feem ntau tshwm sim raws li cov metalloid nyob rau hauv chav tsev kub, thaum arsine yog ib tug roj uas yog flammable thiab lom.
Arsenic yog dab tsi?
Arsenic yog cov khoom siv tshuaj muaj atomic tooj 33 thiab cov cim tshuaj As. Feem ntau, nws tshwm sim raws li grey xim metalloid. Tsis tas li ntawd, cov hlau no ib txwm muaj nyob rau hauv cov ntxhia sib txawv ua ke nrog lwm cov ntsiab lus xws li sulfur thiab hlau. Txawm li cas los xij, peb tuaj yeem pom nws ua cov khoom siv lead ua ntshiab thiab. Tsis tas li ntawd, muaj ntau ntau yam sib txawv ntawm arsenic, tab sis cov isotope nrog cov xim hlau zoo li feem ntau yog siv rau hauv kev lag luam. Ntxiv mus, arsenic tshwm sim nyob rau hauv cov xwm li monoisotopic metalloid. Qhov ntawd txhais tau tias; Nws muaj ib qho isotope ruaj khov.
Arsenic yog p-block keeb. Nws nyob hauv pawg 15 thiab lub sijhawm 4 ntawm lub sijhawm teem sijhawm. Cov txheej txheem electron ntawm no metalloid yog [Ar]3d104s24p3 Tsis tas li ntawd, qhov no metalloid yog nyob rau hauv ib tug solid-state ntawm chav tsev kub. Thaum cua sov, nws tuaj yeem raug sublimation.
Feem ntau, arsenic yog siv los ua ib feem ntawm cov hlau lead. Tsis tas li ntawd, nws muaj txiaj ntsig zoo li dopant hauv semiconductors. Tsis tas li ntawd, oxide compounds ntawm arsenic muaj txiaj ntsig zoo hauv kev tsim cov tshuaj tua kab, tshuaj tua kab, tshuaj tua kab, thiab lwm yam. Txawm li cas los xij, nws tsis yog siv ntau tam sim no vim nws cov tshuaj lom.
Muaj peb hom allotropic ntawm arsenic: grey, daj thiab dub arsenic. Daim ntawv tshaj plaws thiab muaj txiaj ntsig yog grey arsenic. Cov qauv siv lead ua ntawm arsenic yog rhombohedral. Thaum xav txog nws cov khoom sib nqus, arsenic yog diamagnetic. Grey arsenic yog cov khoom nkig vim yog cov tshuaj tsis muaj zog ntawm cov txheej txheem ntawm allotrope. Nws kuj muaj qhov hardness tsawg.
Arsine yog dab tsi?
Arsine yog ib qho roj av uas muaj cov tshuaj formula AsH 3 Nws yog ib qho inorganic compound thiab yog flammable thiab lom thiab. Xav txog nws lwm yam khoom, cov molar loj ntawm nws yog 77 g / mol. Nws zoo nkaus li tsis muaj xim tsis muaj roj thiab muaj ntxhiab tsw tsw. Tsis tas li ntawd, lub arsine molecule muaj trigonal pyramidal geometry. Tsis tas li ntawd, cov roj no yog denser dua huab cua thiab yog me ntsis dej-soluble.
Ntxiv mus, lub conjugate acid ntawm cov roj no yog arsonium. Feem ntau, peb xav txog qhov sib xyaw ua ke no ua ib qho chaw ruaj khov, vim tias nyob rau hauv chav tsev kub, nws decomposes qeeb heev. Thaum kub siab dua, qhov decomposition yog sai, thiab nws tsim arsenic thiab hydrogen gas. Qee lwm yam xws li av noo, lub teeb, catalysts, thiab lwm yam tuaj yeem pab txhawb tus nqi ntawm arsine decomposition.
Qhov txawv ntawm Arsenic thiab Arsine yog dab tsi?
Arsine yog cov tshuaj lom neeg uas tau los ntawm kev sib xyaw ntawm arsenic thiab hydrogen atoms. Yog li, qhov sib txawv tseem ceeb ntawm arsenic thiab arsine yog tias arsenic yog cov khoom siv tshuaj, thaum arsine yog cov tshuaj lom neeg. Arsenic yog cov khoom siv tshuaj muaj atomic tooj 33 thiab cov cim tshuaj As. Meanwhile, arsine yog ib tug gaseous compound uas muaj cov tshuaj formula AsH3 Dhau li ntawd, arsenic feem ntau tshwm sim raws li ib tug metalloid nyob rau hauv chav tsev kub, thaum arsine yog ib tug roj uas yog flammable thiab lom.
Ntxiv mus, arsenic zoo li cov xim grey xim hlau, tab sis arsine zoo li cov roj tsis muaj xim uas muaj ntxhiab tsw tsw. Yog li, qhov no yog lwm qhov sib txawv ntawm arsenic thiab arsine. Tsis tas li ntawd, arsenic yog dej-insoluble thaum arsine yog me ntsis dej-soluble. Thiab, cov qauv siv lead ua ntawm arsenic yog rhombohedral thaum lub geometry ntawm arsine yog trigonal pyramidal.
Summary – Arsenic vs Arsine
Arsine yog cov tshuaj lom neeg uas tau txais los ntawm kev sib xyaw ntawm arsenic thiab hydrogen atoms. Qhov sib txawv tseem ceeb ntawm arsenic thiab arsine yog tias arsenic yog ib qho tshuaj lom neeg, thaum arsine yog cov tshuaj lom neeg.
