Qhov sib txawv tseem ceeb ntawm carbon thiab graphite yog cov pa roj carbon monoxide yog cov tshuaj lom neeg thaum lub graphite yog ib qho allotrope ntawm carbon.
Carbon thiab graphite yog ob qho tib si carbon cov ntaub ntawv uas graphite yog ib qho allotrope ntawm cov pa roj carbon thiab cov ntawv ruaj khov tshaj plaws ntawm carbon. Cov pa roj carbon monoxide yog nonmetal uas tib neeg paub txij thaum ub. Tib neeg siv ntau hom carbon, uas peb hu ua carbon allotropes, xws li charcoal, graphite soot thiab pob zeb diamond. Yav dhau los, tib neeg tsis paub tias cov tebchaw no yog cov qauv sib txawv ntawm cov pa roj carbon ntau thiab tom qab ntawd tsuas yog thaum cov kws tshawb fawb pom txog cov allotropes ntawm carbon. Lo lus carbon derived los ntawm Latin lo lus carbo, uas txhais tau tias charcoal. Cov pa roj carbon monoxide yog ib yam tshwm sim tshwm sim, thiab nws yog qhov thib plaub tshaj plaws nyob rau hauv qhov xwm txheej. Nws ua lub luag haujlwm tseem ceeb hauv tib neeg thiab cog lub neej los ntawm nws lub voj voog carbon.
carbon yog dab tsi?
Carbon yog cov khoom siv tshuaj lom neeg muaj tus lej atomic 6 thiab cov cim tshuaj C. Peb tuaj yeem categorize nws li nonmetal thiab nws kuj yog p block element nyob rau hauv lub sij hawm ntawm lub ntsiab lus. Cov khoom no yog tetravalent, txhais tau tias nws muaj plaub valence electrons thiab yog li, nws tuaj yeem tsim plaub covalent tshuaj bonds. Muaj peb lub isotopes loj ntawm lub caij no uas ib txwm tshwm sim; C-12 thiab C-13 ruaj khov thaum C-14 yog cov xov tooj cua.
Daim duab 01: Graphite thiab Pob zeb diamond yog cov paub zoo tshaj plaws Allotropes ntawm Carbon
Qee cov lus tseeb txog carbon muaj raws li hauv qab no:
- Atomic tus lej yog 6.
- qauv atomic hnyav yog 12.
- Electron configuration is [He] 2s2 2p2
- Lub xeev ntawm tus qauv ntsuas kub thiab siab yog lub xeev ruaj khov.
- Undergo sublimation ntawm 3642 °C
- Cov khoom ruaj khov feem ntau yog graphite thiab pob zeb diamond.
- Oxidation xeev - feem ntau ruaj khov oxidation xeev yog +4, thiab +2 kuj muaj.
Ntxiv mus, cov tshuaj no tuaj yeem ua rau sublimation ntawm qhov kub thiab txias (siab tshaj qhov siab tshaj plaws melting point hlau xws li tungsten). Qhov tseem ceeb tshaj plaws, cov khoom no tiv taus oxidation dua li cov hlau thiab tooj liab. Cov pa roj carbon monoxide yog cov tshuaj tseem ceeb uas ua rau cov qauv ntawm cov organic sib txuas, thiab nws kuj tshwm sim hauv cov tshuaj inorganic.
Graphite yog dab tsi?
Graphite yog ib qho ruaj khov allotrope ntawm carbon. Ib qho allotrope yog ib yam khoom uas txhua yam ntawm ob lossis ntau qhov sib txawv ntawm lub cev uas muaj peev xwm muaj nyob. Qhov no allotrope ib txwm tshwm sim, thiab nws yog ib daim ntawv crystalline. Peb tuaj yeem pom cov khoom sib xyaw no ua ib qho tseem ceeb hauv metamorphic thiab igneous pob zeb. Qhov no yog cov ntxhia uas muaj qee tus yam ntxwv tshwj xeeb uas muaj txiaj ntsig zoo hauv kev xav tau kev lag luam. Piv txwv li, nws yog mos heev, thiab yog li, nws muaj peev xwm cleave nrog me ntsis siab thov rau nws. Tsis tas li ntawd, nws muaj qhov tshwj xeeb qis heev. Nyob rau hauv sib piv, cov tshuaj no yog heev resistant rau tshav kub. Nws yog ze li inert rau kev sib cuag nrog lwm yam khoom siv.
Daim duab 02: Cov Qauv Tshuaj ntawm Graphite
Thaum xav txog cov qauv ntawm graphite, muaj cov txheej txheem ntawm cov pa roj carbon atoms nyob rau hauv uas ib txheej muaj lub network ntawm carbon atoms. Nyob ntawd, ib qho carbon atom txuas nrog peb lwm cov pa roj carbon atom ntawm covalent bonds. Yog li ntawd, cov pa roj carbon txheej yog planar. Cov hluav taws xob ntxiv ntawm txhua cov pa roj carbon atom nyiam tsim cov huab cua electron ua ke. Cov huab hluav taws xob no tseem ceeb hauv hluav taws xob conductivity.
Qhov txawv ntawm Carbon thiab Graphite yog dab tsi?
Carbon yog cov khoom siv tshuaj muaj tus lej atomic 6 thiab cov cim tshuaj C thaum graphite yog ib qho ruaj khov allotrope ntawm carbon. Qhov no yog qhov sib txawv tseem ceeb ntawm carbon thiab graphite. Ntxiv mus, carbon yog ib tug nonmetal uas yuav tshwm sim nyob rau hauv sib txawv qauv uas peb lub npe raws li allotropes xws li graphite, pob zeb diamond, charcoal, thiab lwm yam. Raws li, cov tshuaj qauv ntawm graphite yog tshwj xeeb los ntawm lwm cov allotropes uas muaj ib tug network ntawm carbon atoms nyob rau hauv uas txhua carbon. atom muaj peb daim ntawv cog lus nyob ib puag ncig lawv (nrog rau lwm cov pa roj carbon atoms) thiab huab cua hluav taws xob uas tuaj yeem ua hluav taws xob. Lwm cov allotropes ntawm carbon tsis tuaj yeem ua hluav taws xob. Li no, qhov no yog qhov sib txawv loj ntawm carbon thiab graphite.
Cov hauv qab no infographic muab cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm carbon thiab graphite.
Summary – Carbon vs Graphite
Carbon yog cov tshuaj tseem ceeb uas tsim cov khoom muaj sia. Graphite yog ib hom kab mob uas tshwm sim los ntawm carbon. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm cov pa roj carbon thiab graphite yog cov pa roj carbon monoxide yog cov khoom siv tshuaj lom neeg thaum lub graphite yog ib qho allotrope ntawm carbon.
