A metalloid yog ib lub caij uas muaj cov khoom uas yog nruab nrab ntawm cov hlau thiab nonmetals. Metalloids tuaj yeem yog hu ua semimetals. Nyob rau lub sij hawm lub sij hawm, cov ntsiab lus xim daj, uas feem ntau ciam teb rau stair-step kab, suav hais tias yog metalloids.
Yog li ntawd, uas yog metalloid?
Cov metalloids ; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) thiab astatine (At) yog cov ntsiab lus pom nyob rau hauv cov kauj ruam zoo li kab ntawm cov hlau. thiab non-metals ntawm lub sij hawm. Metalloids muaj cov khoom ntawm cov hlau thiab tsis yog hlau.
Kuj Paub, vim li cas lawv hu ua metalloids? Tsis zoo li lwm tsev neeg ntawm cov ntsiab lus xws li cov pa roj, alkali hlau, thiab halogens, lub metalloids tsim ib kab kab pheeb ces kaum ntawm lub rooj zaum tsis yog kab ntsug. Antimony thiab tellurium feem ntau yog siv hauv cov hlau alloys. Tellurium tau txais nws lub npe los ntawm lo lus Latin "tellus" uas txhais tau tias "lub ntiaj teb."
Thiab cov lus nug yog, dab tsi yog metalloid thiab piv txwv?
Txhais rau metalloids : cov khoom nrog cov khoom nruab nrab ntawm cov hlau thiab nonmetals. Boron, silicon, germanium, arsenic, antimony, tellurium, thiab polonium yog metalloids . Metalloids zoo li semiconductors; silicon yog qhov zoo tshaj plaws paub piv txwv ntawm ib tug semiconductor.
Lwm lub npe rau metalloid yog dab tsi?
Boron, silicon, germanium, arsenic, antimony, thiab tellurium feem ntau lees paub tias yog metalloids . Nyob ntawm tus kws sau ntawv, ib lossis ntau dua los ntawm selenium, polonium, lossis astatine qee zaum ntxiv rau hauv daim ntawv. Boron qee zaum raug cais tawm, los ntawm nws tus kheej, lossis nrog silicon. Qee zaum tellurium tsis suav tias yog ib qho metalloid.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog metalloid nyob qhov twg lawv pom?
Cov metalloids yog ib pawg ntawm cov ntsiab lus nyob rau hauv lub sij hawm lub rooj. Lawv nyob rau sab xis ntawm cov hlau tom qab hloov pauv thiab sab laug ntawm cov hlau tsis yog hlau.Metalloids muaj qee yam khoom sib xws nrog cov hlau thiab qee qhov sib xws nrog cov hlau tsis muaj hlau
