Cov pa roj carbon tsis muaj cov khoom siv lub cev ntawm cov hlau. Sab xis yog cov pa roj los yog cov hlau tsis muaj hlau (noble thiab halogengases) thiab ntawm cov rooj zaum feem ntau muaj cov ntaiv ntawm sab xis. Txhua yam ntawm lub staircase, yog cais raws li a metalloid . Hauv qhov no, carbon yog nonmetal.
Ib yam li ntawd, puas yog carbon tsis yog hlau lossis metalloid?
Txawm hais tias tsis muaj qhov tshwj xeeb, lo lus tseem siv tau nyob rau hauv cov ntaub ntawv ntawm chemistry. Rau qhov feem ntau lees paub metalloids yog boron, silicon, germanium, arsenic, antimony, thiab tellurium. Tsib lub ntsiab lus tsis tshua muaj ntau dua li cais: carbon , aluminium, selenium, polonium, andastatine.
Qhov thib ob, yog cov pa roj carbon monoxide puas tau? Malleable . Txhais: Malleable hauv carbon yog ib qho tsis yog = metallic compound, uas nws crystal structureis xws li uas tsis conductive rau kev ua tau zoo . Ductile txhais tau tias "tuaj yeem rub mus rau hauv cov hlau", zoo li tooj liab orgold.
Tom qab ntawd, 8 metalloids yog dab tsi?
Cov metalloids ; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) thiab astatine (At) yog cov ntsiab lus pom raws li cov kab ntawm cov hlau thiab non-metals ntawm lub periodictable.
Vim li cas Silicon yog metalloid?
Vim li no, silicon yog lub npe hu ua chemicalanalogue rau carbon. Tab sis tsis zoo li carbon, silicon ib metalloid -- qhov tseeb, nws yog qhov feem ntau metalloid hauv ntiaj teb." Metalloid " yog ib lo lus siv rau cov ntsiab lus uas yog cov khoom siv hluav taws xob zoo dua - hluav taws xob - dua li cov hlau tsis zoo, tab sis tsis zoo li hlau.

Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Vim li cas lub cube cag ntawm tus lej tsis zoo yog tus lej tsis zoo?
Tus lej tsis zoo lub voos xwmfab hauv paus yuav tsis zoo Txij li qhov ntsuas tus lej txhais tau tias tsa nws mus rau lub zog thib 3 - uas yog khib - lub voos xwmfab ntawm cov lej tsis zoo yuav tsum yog qhov tsis zoo. Thaum lub qhov hluav taws xob tawm (xiav), qhov tshwm sim tsis zoo. Thaum lub qhov hluav taws xob qhib (daj), qhov tshwm sim yog qhov zoo
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Vim li cas carbon tsis yog hlau?
Cov pa roj carbon monoxide yog cov hlau tsis muaj hlau, thiab cov hlau tsis muaj hlau tsis zoo yog cov khoom siv hluav taws xob tsis zoo vim tias cov qauv ntawm cov khoom siv yog ib qho 'kev npaj kaw.' Silicon andgermanium uas tseem nyob rau hauv pab pawg IVA yog semi-conductors thiab raug cais raws li metalloids
