| nonmetals | ib qho tseem ceeb uas yuav yog a neeg pluag ntawm tshav kub thiab hluav taws xob tam sim no ; nonmetals feem ntau muaj cov khoom opposite rau cov hlau , |
| metalloid | ib lub caij uas nyiam muaj cov khoom uas zoo ib yam li cov hlau thiab nonmetals , |
Hais txog qhov no, puas muaj hlau tsis muaj hluav taws xob?
Nyob ntawd yog tsis muaj hlau uas tsis ua hluav taws xob nkaus, tab sis nyob ntawd yog ib co hlau uas tsis zoo conductors dua lwm tus. Qhov zoo tshaj plaws conductor ntawm hluav taws xob yog cov kub dawb huv, ua raws li cov tooj liab ntshiab thiab cov nyiaj ntshiab uas yog vim li cas lawv siv rau hluav taws xob cov xov hlau.
Tom qab ntawd, lo lus nug yog, yog ci ntsa iab hlau lossis nonmetal? Lub sij hawm nyob rau sab laug cais cov ntsiab lus rau hauv peb pawg: lub hlau (ntsuab nyob rau hauv lub rooj), nonmetals (txiv kab ntxwv), thiab metalloids (xiav). Cov ntsiab lus feem ntau yog hlau . Lawv feem ntau yog ci iab , tuab heev, thiab tsuas yog yaj ntawm qhov kub thiab txias. Lawv cov duab tuaj yeem hloov tau yooj yim rau hauv cov xov hlau nyias lossis cov ntawv tsis muaj kev tawg.
Ib sab saum toj no, uas tsis yog hlau tsis zoo conductor ntawm hluav taws xob?
Tsis yog - hlau yog tsis zoo conductors ntawm tshav kub thiab hluav taws xob tsuas yog Graphite. Ib co piv txwv ntawm tsis yog – hlau yog carbon, oxygen, sulfur, phosphorous, thiab ntau ntxiv.
Cov hlau twg tuaj yeem ua hluav taws xob?
Electric Conductivity Feem ntau cov hlau ua hluav taws xob mus rau ib qho twg. Qee cov hlau yog cov khoom siv hluav taws xob ntau dua li lwm tus. Tooj, Nyiaj , Aluminium, Kub, Hlau thiab tooj dag yog cov khoom siv hluav taws xob ntau. Cov hlau uas muaj conductive tshaj plaws yog nyiaj , tooj, thiab kub.

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 yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog qhov txawv ntawm tus kws tshaj lij hluav taws xob thiab tus kws tshaj lij hluav taws xob?
Qhov sib txawv tseem ceeb ntawm cov kws tshaj lij hluav taws xob thiab cov kws tshaj lij xov tooj cua yog lawv cov qib kev kawm.Lawv yuav tau dhau ob qho kev xeem ntawv pov thawj RN thiab theradiology cov kws saib xyuas neeg mob daim ntawv pov thawj xws li ib tus tswj hwm los ntawm Lub Koom Haum rau Radiologic & ImagingNursing
Puas yog hluav taws xob tam sim no ntws los ntawm qhov tsis zoo mus rau qhov zoo?
Cov kws tshaj lij hluav taws xob hais tias, hauv hluav taws xob hluav taws xob, hluav taws xob ntws mus rau ib qho kev taw qhia: tawm ntawm qhov zoo ntawm lub roj teeb thiab rov qab mus rau qhov tsis zoo. Cov kws tshaj lij hauv hluav taws xob hais tias hluav taws xob ntws mus rau lwm qhov kev taw qhia: tawm ntawm qhov tsis zoo ntawm lub roj teeb thiab rov qab mus rau qhov zoo davhlau ya nyob twg
