Crystal Qauv . Lub Crystal qauv ntawm pob zeb diamond yog lub ntsej muag-centered cubic lossis FCC lattice. Txhua cov pa roj carbon atom koom nrog plaub lwm cov pa roj carbon atom hauv tetrahedrons tsis tu ncua (triangular prisms).
Raws li txoj cai, cov qauv ntawm pob zeb diamond thiab graphite yog dab tsi?
Qauv thiab kev sib raug zoo Graphite muaj covalent loj heev qauv nyob rau hauv uas: txhua cov pa roj carbon atom koom nrog peb lwm cov pa roj carbon atom los ntawm covalent bonds. cov pa roj carbon atoms tsim cov khaubncaws sab nraud povtseg nrog hexagonal kev npaj ntawm atoms.
Tsis tas li ntawd, lub pob zeb diamond molecule yog dab tsi? Ob leeg pob zeb diamond thiab graphite yog ua tag nrho tawm ntawm cov pa roj carbon monoxide, zoo li yog qhov tsis ntev los no pom buckminsterfullerene (ib qho kev ncaws pob-pob-zoo li molecule muaj carbon 60 atoms). Txoj kev uas cov pa roj carbon atoms tau teem rau hauv qhov chaw, txawm li cas los xij, txawv rau peb cov ntaub ntawv, ua rau lawv allotropes ntawm carbon.
Xav txog qhov no, dab tsi yog cov khoom ntawm pob zeb diamond?
Lub cev muaj zog ntawm pob zeb diamond
- Nws muaj qhov kub thiab txias heev (yuav luag 4000 ° C). Muaj zog heev carbon-carbon covalent bonds yuav tsum tau tawg thoob plaws hauv cov qauv ua ntej melting tshwm sim.
- nyuaj heev.
- tsis ua hluav taws xob.
- yog insoluble nyob rau hauv dej thiab organic solvents.
Dab tsi yog pawg pob zeb diamond nyob hauv?
| Lub cev muaj zog ntawm pob zeb diamond | |
|---|---|
| Kev faib tshuaj | Native keeb - Carbon |
| Mohs Hardness | 10. Pob zeb diamond yog cov ntxhia nyuaj tshaj plaws. Txawm li cas los xij, lub hardness ntawm pob zeb diamond yog kev taw qhia. Nws yog qhov nyuaj tshaj plaws rau nws cov dav hlau octahedral thiab softest parallel rau nws cov dav hlau cubic. |
| Specific Gravity | 3.4 rau 3.6 |

Koj puas tuaj yeem muab cov pob zeb tso rau hauv pob zeb tumbler?
Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
Lub npe ntawm lub raj los ntawm cov pob zeb molten ntws yog dab tsi?
Lub raj lava tsim thaum lub npoo ntawm lava txias thiab tawv, thaum lub molten sab hauv ntws los ntawm thiab ntws tawm. 21. Tshauv yog qhov thib ob tsawg tshaj plaws pyroclast
Lub npe rau lub pob zeb nruab nrab ntawm cov pob zeb uas txias heev yog dab tsi?
Extrusive igneous pob zeb
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Dab tsi ntawm pob zeb ua rau ib qho chaw pob zeb?
Sedimentary pob zeb
