Teb: Cov hlau yog qhov zoo tshaj plaws ntawm hluav taws xob thiab hluav taws xob vim cov atoms hauv cov hlau tsim cov matrix los ntawm cov hluav taws xob sab nraud tuaj yeem txav tau yooj yim. Es tsis txhob orbiting lawv cov atoms, lawv tsim ib lub hiav txwv ntawm electrons uas nyob ib ncig ntawm lub zoo nuclei ntawm interacting hlau ions.
Vim li cas cov hlau zoo conductors ntawm tshav kub thiab hluav taws xob?
Metals yog cov conductors zoo (ob qho tib si ntawm tshav kub thiab hluav taws xob) vim tsawg kawg ib lub tshuab hluav taws xob ib lub atom yog dawb: piv txwv li, nws tsis khi rau ib qho atom tshwj xeeb, tab sis yog, Hloov chaw, muaj peev xwm txav tau yooj yim thoob plaws hauv cov hlau.
Vim li cas cov hlau zoo conductors ntawm hluav taws xob thiab iav tsis yog?
Cov hlau yog cov hluav taws xob zoo ntawm cov hluav taws xob vim lawv muaj tsis muaj zog thiab lawv muaj cov hluav taws xob dawb. iav yog ib tug phem conductor ntawm hluav taws xob vim nws muaj siab resistivity thiab tsis muaj dawb electrons.
Vim li cas cov hlau ua hluav taws xob ntau dua?
Hlau ua hluav taws xob vim lawv muaj "dawb electrons." Tsis zoo li feem ntau lwm yam teeb meem, metallic bonding yog tshwj xeeb vim hais tias cov electrons tsis khi rau ib qho atom. Qhov no tso cai rau cov delocalized electrons ntws los teb rau qhov sib txawv.
Txhua cov hlau puas muaj hluav taws xob?
Thaum txhua cov hlau tuaj yeem ua hluav taws xob, qee cov hlau feem ntau siv vim yog cov khoom siv hluav taws xob ntau. Qhov piv txwv tshaj plawsyog tooj liab. Lwm qhov kev xav tsis zoo yog qhov ntshiab Kub yog qhov zoo tshaj plaws tus neeg xyuas pib ntawm hluav taws xob. …
