Cov pa roj carbon yog tsis yog- hlau , thiab tsis- hlau yog cov conductors tsis zoo ntawm hluav taws xob vim hais tias cov qauv ntawm cov khoom yog "kaw-packed kev npaj." Silicon andgermanium uas tseem nyob rau hauv pab pawg IVA yog semi-conductors thiab raug cais raws li metalloids.
Tsuas yog li ntawd, puas yog carbon hlau lossis tsis yog hlau?
Cov pa roj carbon yog ib qho ruaj khov tsis yog - hlau keeb. Ntshiab carbon tuaj yeem muaj nyob hauv ntau hom ntawv. Feem ntau ob yog pob zeb diamond thiab graphite.
Tsis tas li ntawd, vim li cas graphite tsis yog hlau? Yog vim li cas graphite ib tsis hlau txawm hais tias nws muaj ntau yam khoom ntawm hlau ? Cov pa roj carbon feem ntau tsim muaj zog, covalent bonds nrog nws tus kheej thiab yog li feem ntau xav txog asa non-metallic keeb. Txawm li cas los xij, graphite muaj lub delocalisedbonding network nyob rau hauv dav hlau nrog tsis muaj zog van der Waals kev sib cuam tshuam ntawm cov dav hlau.
Tom qab, lo lus nug yog, hom hlau twg yog carbon?
Cov pa roj carbon steel, los yog dawb- carbon steel, yog a hlau hlau alloy. Nws yog kev sib xyaw ntawm ob lub ntsiab lus, hlau thiab carbon.
Puas yog Pob Zeb Diamond yog hlau?
Pob zeb diamond yog ib qho ntawm cov allotropes ntawm carbon. Nws yog categorized li Non- hlau vim yog cov ntsiab lus hauv qab no. Nws yog ib qho khoom siv hluav taws xob tsis zoo ntawm cov cua sov thiab hluav taws xob. Tsis nyob rau hauv tag nrho cov reactive thiab tsis tsim oxides. Tab sis nws muaj deviations los ntawm cov khoom uas tsis yog- hlau.

Puas yog Phosphorus yog hlau lossis tsis yog hlau?
Phosphorus yog cov hlau tsis muaj hlau uas nyob hauv qab nitrogen hauv pawg 15 ntawm lub sijhawm. Cov khoom no muaj nyob rau hauv ntau hom, uas yog dawb thiab liab yog qhov zoo tshaj plaws paub. Dawb phosphorus yog twv yuav raug hu ntau exciting ntawm ob
Qhov laj thawj twg zoo tshaj plaws piav qhia vim li cas cov hlau tsis muaj ductile es tsis nkig?
Cov hlau yog ductile es tsis txhob nkig vim tias lawv muaj cov ntawv cog lus hloov tau. Ductility txhais tau hais tias muaj peev xwm ntawm cov hlau los kos rau hauv cov xov hlau. Cov hlau muaj cov khoom sib txuas yooj yim. Qhov kev hloov pauv no tso cai rau lawv ua cov khoom siv
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Vim li cas tus choj ntsev siv tsis yog hlau?
Ntsev choj Saib yog vim li cas ib daim hlau tsis tuaj yeem siv los ntawm kev siv ntsev? Tus choj ntsev tso cai ntws ntawm ions (them nqi) los tiv thaiv tus nqi tsim tawm hauv cov kev daws teeb meem ionic. Ib txoj hlua yuav tsis ua li ntawd
Vim li cas nitrogen tsis yog hlau?
Nws yog ib qho roj, raws li nws muaj nyob rau hauv cov txheej txheem cov khoom siv roj, nws muaj noshine, tsis tuaj yeem ua hluav taws xob lossis. Ua tsis zoo, tib yam nrog cua sov. Chemically nws tuaj yeem oxidize thiab txo qis thaum hlau tsuas yog oxidize, thiab nitrogen oxides hnov mob nrog dej los ua acids, thaum hlau ua hauv paus
