Ib qho tshuaj uas tsis yog xim hlau uas yog cov khoom siv hauv tsev neeg carbon.
Silicon, qhia los ntawm lub cim atomic Si, yog qhov thib ob ntau tshaj plaws nyob rau hauv lub ntiaj teb lub pob zeb, thiab cov khoom uas muaj ntau tshaj plaws yog oxygen. Silicon tsis tshwm sim nyob rau hauv qhov nyob rau hauv nws cov elemental daim ntawv. Silicon muaj nyob rau hauv yuav luag tag nrho cov pob zeb ua ke nrog oxygen los tsim silica. Thaum silicon ua ke nrog lwm cov khoom xws li hlau, txhuas lossis potassium, silicate yog tsim. Tsis tas li ntawd, cov tshuaj silicon muaj nyob rau hauv cov huab cua, dej ntuj, ntau cov nroj tsuag, thiab lub cev ntawm qee cov tsiaj. Silicon yog cov khoom siv tseem ceeb hauv kev tsim cov chips hauv computer, transistors, silicon diodes, thiab lwm yam khoom siv hluav taws xob thiab hloov khoom siv vim nws cov qauv atomic, uas ua rau lub caij no yog qhov zoo tshaj plaws semiconductor. Silicon feem ntau doped, los yog sib tov, nrog rau lwm cov ntsiab lus, xws li boron, phosphorus, thiab arsenic, los hloov nws cov khoom conductive.
