Muaj ntau tshaj peb allotropes ntawm carbon. Cov no suav nrog pob zeb diamond, graphite, graphene, carbon nanotubes, fullerenes, thiab carbon nanobuds. Txhua carbon atom nyob rau hauv lub pob zeb diamond yog covalently bonded rau plaub lwm carbons nyob rau hauv ib peb -dimensional array.
Kuj kom paub yog, dab tsi yog hom sib txawv ntawm allotropes?
Muaj ob peb allotropes ntawm carbon. Allotropes Ntawm CarbonAllotropes ntawm carbon: a) Pob zeb diamond, b) Graphite, c) Lonsdaleite, d) C60 (Buckminsterfullerene los yog buckyball), e) C540, f) C70, g) Amorphous carbon, thiab h) ib leeg-walled carbon nanotube, los yog buckytube.
Kuj Paub, peb cov allotropes ntawm phosphorus yog dab tsi lawv txawv li cas? Muaj ob peb sib txawv allotropes ntawm phosphorus , mas peb cov ntaub ntawv muaj xws li dawb, liab, thiab dub phosphorus . Allotropic daim ntawv ntawm phosphorus muaj cov khoom sib txawv ntawm lub cev, tab sis cov tshuaj lom neeg zoo sib xws.
Ntawm no, muaj pes tsawg tus allotropes muaj?
Yim allotropes ntawm carbon: a) pob zeb diamond, b) graphite, c) lonsdaleite, d) C60 buckminsterfullerene, e) C540, Fullerite f) C70, g) amorphous carbon, h) zig-zag ib leeg-walled carbon nanotube.
Yuav ua li cas yog allotropes tsim?
Allotropes yog cov qauv txheej txheem sib txawv ntawm tib lub caij thiab tuaj yeem nthuav tawm cov khoom sib txawv ntawm lub cev thiab cov cwj pwm tshuaj lom neeg. Kev hloov pauv ntawm cov ntaub ntawv allotropic yog tshwm sim los ntawm tib lub zog uas cuam tshuam rau lwm cov qauv, piv txwv li, siab, lub teeb, thiab kub.

Dab tsi yog qee qhov piv txwv ntawm allotropes?
Piv txwv ntawm Allotropes Txhawm rau txuas ntxiv cov piv txwv ntawm cov pa roj carbon monoxide, indiamond, cov pa roj carbon atoms tau sib koom ua ke los ua ib qho tetrahedrallattice. Hauv graphite, cov atoms daim ntawv cog lus rau daim ntawv ntawm ahexagonal lattice. Lwm cov allotropes ntawm carbon muaj xws ligraphene thiab fullerenes. O2 thiab ozone, O3, yog allotropes ntawm oxygen
Dab tsi yog equidistant los ntawm peb sab ntawm daim duab peb sab?
Lub ntsiab lus uas sib npaug rau txhua sab ntawm daim duab peb sab yog hu ua incenter: Ib qho nruab nrab yog ib qho kab uas muaj ib qho ntawm nws qhov kawg ntawm lub vertex ntawm daim duab peb sab thiab lwm qhov kawg ntawm qhov nruab nrab ntawm sab opposite lub vertex. Peb qhov nruab nrab ntawm ib daim duab peb sab sib ntsib hauv centroid
