1.2. Arsenic (atomic tooj, 33; txheeb ze atomic mass, 74.92) muaj tshuaj lom neeg thiab lub cev muaj zog nruab nrab ntawm ib tug hlau thiab a non-metal, thiab feem ntau hu ua metalloid lossis semi-hlau.. Nws belongs rau Pawg VA ntawm Lub Sij Hawm Lub Sij Hawm, thiab tuaj yeem muaj nyob hauv plaub lub xeev oxidation: -3, 0, +3, thiab +5.

Arsenic (atomic tooj, 33; txheeb ze atomic mass, 74.92) muaj tshuaj lom neeg thiab lub cev muaj zog nruab nrab ntawm cov hlau thiab tsis yog hlau, thiab feem ntau hu ua metalloid lossis semi-hlau. Nws belongs rau Pawg VA ntawm Lub Sij Hawm Lub Sij Hawm, thiab tuaj yeem muaj nyob hauv plaub lub xeev oxidation: -3, 0, +3, thiab +5.
Vim li cas arsenic yog metalloid?
Arsenic yog lub ntsiab lus thib peb hauv kab thib kaum tsib ntawm lub sijhawm. Nws raug cais raws li metalloid vim nws muaj qee yam khoom zoo ib yam li cov hlau thiab lwm tus ntawm cov hlau tsis yogArsenic atoms muaj 33 electrons thiab 33 protons nrog 5 valence electrons nyob rau hauv lub plhaub sab nrauv. Arsenic muaj nyob rau hauv ib tug xov tooj ntawm allotropes.
Puas tsis yog hlau arsenic?
Khoom thiab cov tshuaj tiv thaiv. Hauv nws lub xeev ruaj khov tshaj plaws, arsenic yog cov hlau-grey, nkig khoom nrog qis thermal thiab hluav taws xob conductivity. Txawm hais tias qee cov ntaub ntawv ntawm cov arsenic yog cov hlau zoo li, lub caij yog qhov zoo tshaj plaws uas yog cov tsis yog hlau.
Puas arsenic muaj hlau khoom?
Arsenic yog ib qho ci nyiaj-grey metalloid; nws cov hluav taws xob sab nraud tsis muaj kev ywj pheej txav mus rau hauv cov qauv siv lead ua vim lawv tau tsau rau hauv txoj hauj lwm hauv covalent daim ntawv cog lus. Nws muaj cov xim hlau nplaumtab sis nkig tsis muaj cov khoom siv kho tshuab zoo.

Puas yog boron yog hlau nonmetal lossis metalloid?
Boron yog ib yam tsis yog xim hlau thiab tsuas yog tsis yog hlau ntawm pab pawg 13 ntawm lub sijhawm cov ntsiab lus. Boron yog tsis muaj electron, muaj qhov tsis muaj p-orbital. Nws muaj ntau hom, feem ntau yog amorphous boron, hmoov tsaus, tsis muaj zog rau oxygen, dej, acids thiab alkalis .
Cov hlau nplaum puas lo rau txhuas lossis hlau?
Metals uas tsis nyiam Magnets Hauv lawv lub xeev ntuj, cov hlau xws li txhuas, tooj dag, tooj liab, kub, txhuas thiab nyiaj tsis nyiam cov hlau nplaum vim tias lawv yog cov hlau tsis muaj zog. Txawm li cas los xij, koj tuaj yeem ntxiv cov khoom xws li hlau lossis hlau rau cov hlau tsis muaj zog kom ua rau lawv muaj zog .
Vim li cas ib yam khoom hlau tsis muaj hlau nplaum nyiam rau cov hlau nplaum?
Thaum cov hlau nplaum raug coj los ze rau cov khoom siv ferromagnetic yav dhau los uas tsis muaj hlau nplaum, nws ua rau cov hlau nplaum hauv zos ntawm cov khoom uas tsis zoo li cov ncej ze tshaj, ib yam li hauv. unmagnetized khoom rau cov hlau nplaum raws li daim duab hauv .
Puas yog protactinium yog hlau nonmetal lossis metalloid?
Protactinium (yav tas los protoactinium) yog cov khoom siv tshuaj nrog lub cim Pa thiab tus lej atomic 91. Nws yog tuab, silvery-grey actinide hlauuas nkag tau nrog oxygen, dej. vapor thiab inorganic acids . YPuas yog protactinium tsis yog hlau?
Dab tsi yog hlau lossis hlau?
Steel muaj zog dua hlau (yield thiab qhov kawg tensile zog) thiab tawv dua ntau hom hlau ib yam nkaus (feem ntau ntsuas raws li tawg toughness). Cov hom hlau feem ntau muaj qhov sib ntxiv ntawm tsawg dua. 5% carbon los ntawm qhov hnyav. … Lwm cov ntsiab lus uas feem ntau pom hauv cov hlau yog manganese, silicon, phosphorus, thiab sulfur .
