Pob zeb diamond yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws paub, yog pob tshab rau lub teeb, thiab tsis ua hluav taws xob kiag li. Graphite yog mos, grey, thiab tuaj yeem ua hluav taws xob zoo. Xws li cov khoom sib txawv, los ntawm ob yam khoom uas tsim los ntawm tib hom atoms!
Peb qhov txawv ntawm pob zeb diamond thiab graphite yog dab tsi?
Pob zeb diamond yog ib qho hluav taws xob insulator thaum graphite yog ib qho hluav taws xob zoo. Pob zeb diamond feem ntau yog pob tshab, tab sis graphite yog opaque. Pob zeb diamond yog pom tseeb tias muaj nuj nqis ntau dua li graphite. Graphite yog pheej yig heev uas nws yog siv los ua xaum xaum.
Dab tsi yog qhov txawv ntawm cov qauv ntawm pob zeb diamond thiab graphite?
Pob zeb diamond: txhua carbon atom bonds rau 4 lwm carbon atoms, WHILST, Graphite: txhua carbon atom bonds rau 3 lwm carbon atoms. Yog li, pob zeb diamond bears ntau dua ntawm cov qauv tetrahedral, whereas graphite siv cov txheej txheem. Lub xub ntiag ntawm cov khaubncaws sab nraud povtseg txhais tau hais tias cov atoms tuaj yeem swb ib leeg yooj yim.
Dab tsi yog qhov sib txawv thiab zoo sib xws ntawm graphite thiab pob zeb diamond?
Pob zeb diamond muaj cov qauv tetrahedral thiab yog cov khoom siv nyuaj tshaj plaws rau txiv neej. Muaj muaj zog covalent bonds ntawm carbon atoms thiab txhua carbon atom yog bonded rau 4 lwm carbon atomsGraphite muaj ib tug hexagonal txheej txheej thiab txhua cov pa roj carbon yog bonded los ntawm muaj zog covalent bonds rau 3 lwm carbon atoms.
Dab tsi yog pob zeb diamond thiab graphite?
Graphite yog ib qho zoo ntawm hluav taws xob tab sis lub pob zeb diamond tsis yog. Yog li, tsuas yog tus yam ntxwv ntawm ob qho tib si yog tsim los ntawm carbon atomsuas muaj qhov tseeb atomic loj uas tsis hloov nrog daim ntawv.
