In pob zeb diamond, tag nrho plaub sab electrons ntawm txhua carbon atom yog 'localized' ntawm cov atoms hauv covalent bonding. Kev txav ntawm electrons raug txwv thiab pob zeb diamond tsis ua hluav taws xob tam sim no.

4 allotropes ntawm carbon yog dab tsi?

Siv daim ntawv qhia tseeb thiab sib txawv ntawm daim npav ua haujlwm los tshawb txog cov khoom sib txawv thiab siv plaub allotropes ntawm carbon - pob zeb diamond, graphite, graphene thiab buckminsterfullerene.

Puas methane yog ib qho allotrope ntawm carbon?

Methane tsis yog ib qho allotrope ntawm carbon, nws yog hydrocarbon compound nrog cov mis CH4. Ib qho allotrope tsis tuaj yeem yog qhov sib xyaw thiab yog li, methane yog cov lus teb zoo. Lo lus allotrope yog hais txog ib lossis ntau hom tshuaj uas tshwm sim hauv tib lub cev.

Vim li cas pob zeb diamond yog ib qho allotrope ntawm carbon?

Pob zeb diamond yog ua los ntawm ntau 3-dimensional molecules. Tsis yog nyob rau hauv cov khaubncaws sab nraud povtseg ib leeg, cov khaubncaws sab nraud povtseg yog sib koom ua ke thiab tsim kom muaj zog dua tab sis tsis yog cov khoom siv hluav taws xob. Nws tsuas yog tsim tawm ntawm cov pa roj carbon, yog li yog ib qho allotrope ntawm carbon.

Dab tsi yog qhov muaj zog tshaj carbon allotrope?

Cov kws tshawb fawb hauv Vienna tau ua tiav daim ntawv ruaj khov ntawm carbyne, lub ntiaj teb cov khoom muaj zog tshaj plaws. Carbyne yog linear acetylenic carbon - ib tug infinitely ntev carbon saw. Nws tuaj yeem suav hais tias yog ib qho allotropentawm carbon.
