Yim allotropes ntawm carbon: a) pob zeb diamond, b) graphite, c) lonsdaleite, d) C₆₀ buckminsterfullerene, e) C₅₄₀, Fullerite f) C₇₀, g) amorphouscarbon, h) zig-zag ib leeg-walled carbon nanotube.

Ib yam li ntawd, nws yog nug, dab tsi lwm yam ntawm allotropes muaj?

Nyob ntawd muaj ntau tshaj peb allotropes ntawm carbon. Cov no suav nrog pob zeb diamond, graphite, graphene, carbonnanotubes, fullerenes, thiab carbon nanobuds. Txhua carbon atom hauv lub pob zeb diamond yog covalently bonded rau plaub lwm yam carbons hauv peb-dimensional array. Lub pob zeb diamond tseem ceeb yog ib qho loj heev molecule.

Tsis tas li ntawd, Allotropic txhais li cas? λλος (allos), lub ntsiab lus 'lwm', thiab τρόπος (tropos), lub ntsiab lus 'zoo, form') yog cov cuab yeej ntawm qee yam tshuaj muaj nyob rau hauv ob lossis ntau hom sib txawv, hauv tib lub cev lub cev, hu ua allotropes ntawm cov ntsiab lus.

Dhau li ntawm qhov no, puas yog tag nrho cov ntsiab lus muaj allotropes?

Ib qho tshuaj element yog hais kom nthuav tawm allotropy thaum nws tshwm sim hauv ob lossis ntau daim ntawv hauv tib lub cev; cov qauv yog hu ua allotropes . Pob zeb diamond thiab graphite yog ob allotropes ntawm keeb carbon. Ozone yog chemically active triatomic allotrope ntawm keeb oxygen.

Dab tsi yog qhov txawv ntawm pob zeb diamond thiab graphite?

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 txhua. Graphite yog mos, grey, thiab tuaj yeem ua hluav taws xob zoo. Xws li txawv cov khoom, los ntawm ob yam khoom uas muaj xws li tib yam ntawm atoms!
