Qhov no txhais tau hais tias txhua cov pa roj carbon atom muaj 'spare' electron(raws li carbon muaj plaub txheej electrons) uas yog delocalised ntawm cov khaubncaws sab nraud povtseg ntawm carbon atoms. Cov khaubncaws sab nraud povtseg tuaj yeem swb rau ib leeg, yog li graphite yog softer dua pob zeb diamond.
Dab tsi ua rau graphite mos?
Peb tuaj yeem pom meej tias graphite tsawg dua li piv rau pob zeb diamonduas ua rau nws mos thiab nplua. … Cov pa roj carbon atoms nyob rau hauv graphite zoo li kev sib raug zoo nrog cov tsis muaj zog intermolecular rog, cia cov khaubncaws sab nraud povtseg ntawm ib leeg. Cov tsis muaj zog intermolecular rog yog hu ua lub zog Van der Waals tsis muaj zog.
Vim li cas graphite mos thiab nplua?
Graphite yog mos thiab nplua vim nws cov pa roj carbon atoms ua ke los ntawm cov nyiaj tsis muaj zog hu ua Van der Waal rog. Cov ntawv cog lus uas txuas cov carbon atoms hauv graphite yog qhov tsis muaj zog, yog li lawv yooj yim tawg, uas ua rau graphite zoo li mos thiab nplua.
Puas yog graphite Cov tshuaj softest?
Graphite yog mos thiab nplua heev. Pob zeb diamond yog cov khoom nyuaj tshaj plaws rau txiv neej. Yog tias ob qho tib si tsuas yog ua los ntawm carbon, dab tsi ua rau lawv muaj zog sib txawv? Cov lus teb yog nyob rau hauv txoj kev uas cov pa roj carbon atom tsim kev sib raug zoo nrog ib leeg.
Dab tsi yog qhov softest tshaj plaws hauv ntiaj teb?
Raws li Mohs nplai, talc, tseem hu ua soapstone, yog cov ntxhia pob zeb zoo tshaj plaws; Nws yog tsim los ntawm ib pawg ntawm cov nplooj ntawv uas tsis muaj zog sib txuas uas zoo li plam sib nrug hauv qhov siab.
