Cov kws qhia Khoom siv: hlau, tooj liab, tooj liab, txhuas, nichrome, graphite, mercury, manganin. INSULATORS : sulfur , paj rwb, cua, ntawv, porcelain, mica, bakelite, polythene.
Yog li ntawd, yog sulfur yog ib tug zoo conductor?
Sulfur yog tus yam ntxwv uas tsis yog-hlau vim itis zoo ib yam nrog 3 lub cev khoom uas teev rau nonmetals. Nws yog ib tug neeg pluag. tus thawj coj ntawm tshav kub thiab hluav taws xob vim tias theelectrons tsis muaj kev txav mus los. Nws muaj highelectronegativity vim nws muaj peev xwm nce electronseasily.
Tsis tas li ntawd, puas yog manganese conductor lossis insulator? Manganese yog qhov zoo tus thawj coj ntawm hluav taws xob, muaj kev tiv thaiv ntawm 1.44 microohms / m. Txawm li cas los xij, nws tsis yog siv los ua tus thawj coj vim tus nqi thiab muaj, thiab txij li tooj liab thiab txhuas yog pheej yig tshaj muaj tus thawj coj.
Ib sab saum toj no, puas yog Polythene tus neeg xyuas pib lossis insulator?
Yas insulator Lawv tsis pub hluav taws xob ntws los ntawm lawv. A yas npog yog qhwv ib ncig ntawm cov xov hluav taws xob, tiv thaiv peb ntawm hluav taws xob shocks.
Puas yog Mercury yog tus neeg xyuas pib lossis cov insulator?
Mercury yog ib tug hnyav, silvery-dawb kua hlau. Piv rau lwm yam hlau, nws yog ib tug neeg pluag tus thawj coj ntawm tshav kub, tab sis ib tug ncaj ncees tus thawj coj ntawm hluav taws xob.

Puas yog tus neeg xyuas pib tsis zoo ntawm cov hluav taws xob tam sim no yog hlau lossis nonmetal?
Tshooj 6 - Lub Sij Hawm Lub Sij Hawm A B nonmetals yog ib qho khoom siv uas zoo li cov neeg ua haujlwm tsis zoo ntawm cov cua sov thiab hluav taws xob tam sim no; nonmetals feem ntau muaj cov khoom sib txawv rau cov hlau, metalloid ib lub caij uas nyiam muaj cov khoom zoo ib yam li cov hlau thiab nonmetals
Koj yuav ua pov thawj li cas tias tam sim no tus neeg xyuas pib tsim cov hlau nplaum?
Txhua tus neeg nqa khoom nqa tam sim no ua rau muaj qhov sib txawv ntawm qhov chaw nyob ib puag ncig nws tus kheej raws li kev tuav ntawm txoj cai sab xis (yog tias cov paib ua raws li tus ntiv tes xoo, cov ntiv tes curlin cov kev taw qhia ntawm cov hlau nplaum)
Dab tsi yog qhov tsim nyog rau electrons ntws los ntawm tus neeg xyuas pib?
Qhov hluav taws xob tam sim no yog dab tsi? Txhawm rau tsim hluav taws xob tam sim no, peb yam xav tau: ib qho khoom siv hluav taws xob (electrons) uas tsis muaj dej ntws, qee hom kev thawb kom txav cov nqi hluav taws xob los ntawm lub voj voog thiab ib txoj hauv kev los nqa cov nqi. Txoj hauv kev los nqa cov nqi feem ntau yog tooj liab
Tus neeg xyuas pib puas yog hlau lossis nonmetal?
Cov ntsiab lus tau muab faib ua cov hlau, tsis yog hlau, thiab metalloids. 2.11: Hlau, Nonmetals, thiab Metalloids. Metallic Elements Nonmetallic cov ntsiab lus Malleable thiab ductile (hloov tau) raws li cov khib nyiab brittle, tawv los yog mos Ua kom sov thiab hluav taws xob tsis zoo conductors
Dab tsi yog cov cuab yeej lossis cov ntaub ntawv uas tus Kws Tshawb Fawb xav tau los txheeb xyuas cov ntaub ntawv nug?
Cov ntaub ntawv raug nug hauv chav kuaj ua txhaum cai yog nruab nrog lub tshuab ntsuas ntsuas, ntsuas cov duab digital, infrared thiab ultraviolet lub teeb ci, cov cuab yeej tshuaj ntsuam video thiab cov cuab yeej tshwj xeeb suav nrog cov khoom siv hluav taws xob tshawb pom electrostatic (EDD) thiab cov khoom siv los ua chemistry
