Khoom Description

Lub caij nrog atomic naj npawb 14 ib txwm tshwm sim hauv cov khoom siv silicate, suav nrog silica, feldspar, thiab mica, uas yog cov khoom tseem ceeb ntawm cov pob zeb xws li quartz thiab sandstone. Ib lub semi-hlau (los yog metalloid), silicon muaj qee yam khoom ntawm ob qho tib si hlau thiab tsis yog hlau.

Zoo li dej - tab sis tsis zoo li feem ntau cov hlau - silicon cog lus nyob rau hauv nws cov kua hauv lub xeev thiab nthuav raws li nws solidifies. Nws muaj cov ntsiab lus siab melting thiab boiling, thiab thaum crystallized tsim ib pob zeb diamond cubic siv lead ua qauv. Tseem ceeb rau silicon lub luag hauj lwm raws li ib tug semiconductor thiab nws siv nyob rau hauv electronics yog lub ntsiab lub atomic qauv, uas muaj xws li plaub valence electrons uas tso cai rau silicon rau daim ntawv cog lus nrog rau lwm yam khoom.

Silicon muaj nyob rau hauv cov xwm txheej ntawm silicon dioxide (xws li qee hom xuab zeb thiab ntau pob zeb). Kev rho tawm ntawm silicon los ntawm silicon dioxide yog lub zog siv zog heev; nws yuav tsum tau 1000-1500 megajoules ntawm thawj lub zog ib kilogram los ua cov qib high-qib silicon rau lub computer chips los yog solar panels.

Qhov no yog ib qho piv txwv zoo heev (nrog rau txhuas) ntawm cov khoom siv uas txwv ntau npaum li cas lub zog xav tau los ua kom cov khoom siv tau (embodied lub zog) dua li cov nplua nuj nyob hauv ntiaj teb. Hauv lwm lo lus yuav tsis muaj qhov tsis txaus ntawm silicon rau kev siv uas tib neeg tau xeeb los; lub zog los ua nws ib txwm yog qhov txwv.
