Fullerenes yog cov ntawv carbon, thiab suav nrog nanotubes thiab buckyballs. Lub nanotube zoo li ib txheej ntawm graphene, dov rau hauv lub raj zoo. Zoo li graphene, nanotubes muaj zog, thiab lawv ua hluav taws xob vim lawv muaj delocalised electrons. …
Pob fullerenes muaj dawb electrons?
Ib tug kheej kheej fullerene ntawm n carbon atoms muaj n pi-bonding electrons, free to delocalize.
Puas C60 puas muaj delocalised electrons?
C60 fullerene tsis tuaj yeem ua hluav taws xob. Txawm hais tias nyob rau hauv txhua lub molecule txhua carbon tsuas yog covalently bonded rau 3 lwm tus thiab lwm cov electrons yog delocalised, cov electrons no tsis tuaj yeem dhia ntawm cov molecules sib txawv.
Puas muaj delocalised electrons hauv graphene?
Graphene muaj qhov taw tes melting siab heev thiab muaj zog heev vim nws qhov loj heev tsis tu ncua ntawm carbon atoms koom nrog covalent bonds. … Zoo li graphite nws ua hluav taws xob zoo vim nws muaj delocalised electronsuas muaj kev ywj pheej txav mus thoob nws qhov chaw.
Ntau npaum li cas delocalised electrons puas muaj graphene?
Qhov no ib qho dawb electron muaj nyob rau hauv p-orbital uas zaum saum cov khoom siv dav hlau. Nyob rau hauv daim ntawv graphene, txhua hexagon muaj ob pi-electrons, uas yog delocalized thiab ua kom muaj hluav taws xob zoo.
