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.
Puas arsenic yog hlau lossis tsis yog hlau?
1.2.
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.
