Thaum muaj cov khoom muaj nyob hauv ntau tshaj ib daim ntawv crystalline, cov ntaub ntawv no hu ua allotropes; Qhov ob feem ntau allotropes ntawm carbon yog pob zeb diamond thiab graphite. … Txhua carbon atom yog covalently bonded ntawm plaub fab ntawm lub tetrahedron rau plaub lwm carbon atoms.
Puas yog allotropes ntawm carbon?
Pob zeb diamond, graphite thiab fullerenes (cov khoom uas suav nrog nanotubes thiab 'buckyballs', xws li buckminsterfullerene) yog peb allotropes ntawm ntshiab carbon.
Puas yog carbon tib lub ntsiab nrog allotropes?
Pob zeb diamond thiab graphite yog ob allotropes ntawm carbon: cov ntaub ntawv ntshiab ntawm tib lub caij uas txawv hauv cov qauv crystalline.
Dab tsi yog cov khoom ntawm allotropes?
Allotropes feem ntau txawv ntawm lub cev muaj zog xws li xim thiab tawv; lawv kuj yuav txawv ntawm cov qauv molecular lossis tshuaj lom neeg, tab sis feem ntau zoo ib yam hauv cov khoom siv tshuaj lom neeg. Pob zeb diamond thiab graphite yog ob allotropes ntawm lub caij carbon.
Yuav ua li cas allotropes ntawm carbon tsim?
Txhua chav tsev tetrahedral muaj cov pa roj carbon sib txuas rau plaub lub atoms uas tau sib koom ua ke rau lwm cov carbons. Qhov no ua rau muaj qhov allotrope ntawm carbon uas muaj a peb-dimensional kev npaj ntawm C-atoms.
