Carbon qhia allotropy vim nws muaj nyob rau hauv ntau hom carbon. Txawm hais tias cov allotropes ntawm cov pa roj carbon monoxide muaj cov qauv siv lead ua sib txawv thiab cov khoom sib txawv ntawm lub cev, lawv cov khoom siv tshuaj yog tib yam thiab qhia cov khoom siv tshuaj zoo sib xws. Pob zeb diamond thiab graphite muaj cim C.
Vim li cas allotropes tsim?
Enantiotropic allotropes muaj ntau daim ntawv, txhua tus yog ruaj khov nyob rau hauv cov txheej txheem sib txawv. Nws muaj peev xwm hloov tau ib daim ntawv mus rau lwm daim ntawv los ntawm kev hloov cov xwm txheej no (xws li kub thiab siab). Cov ntsiab lus carbon, oxygen, sulfur, tin thiab phosphorus tag nrho muaj cov ntaub ntawv allotropic.
Cov ntawv allotropic ntawm carbon yog dab tsi?
Pob zeb diamond, graphite thiab fullerenes (cov khoom uas suav nrog nanotubes thiab 'buckyballs', xws li buckminsterfullerene) yog peb allotropes ntawm ntshiab carbon.
Yuav ua li cas allotropes ntawm carbon tsim?
