Rau qhov feem ntau lees paub metalloids yog boron, silicon, germanium, arsenic, antimony, thiab tellurium. Tsib Cov ntsiab lus tsis tshua muaj kev faib tawm: carbon, aluminium, selenium, polonium, thiab astatin.
Dhau li ntawm no, dab tsi yog cov yam ntxwv ntawm metalloids?
Metalloids feem ntau zoo li hlau tab sis coj zoo li nonmetals. Lub cev, lawv yog ci iab, nkig solids nrog nruab nrab mus rau kuj zoo hluav taws xob conductivity thiab hluav taws xob band qauv ntawm ib tug semimetal los yog semiconductor.
Ib yam li ntawd, plaub yam ntxwv ntawm metalloids yog dab tsi? Lub cev muaj zog ntawm metalloids yog raws li nram no:
- Metalloids muaj lub cev muaj zog.
- Feem ntau, metalloids muaj ib tug hlau luster. Metalloids muaj elasticity tsawg, lawv yog nkig heev.
- Middleweights yog cov ntsiab lus semi-coj, thiab lawv tso cai rau qhov nruab nrab kis ntawm tshav kub.
Dhau li ntawm no, dab tsi yog 3 yam ntxwv ntawm metalloids?
Cov metalloids yog boron, silicon, germanium, arsenic, antimony, thiab tellurium. Cov ntsiab lus no zoo li yog xim hlau; Txawm li cas los xij, lawv tsis ua hluav taws xob zoo li hlau yog li lawv yog semiconductors.
Cov yam ntxwv ntawm metalloids zoo li cov hlau li cas?
Metalloids nyiam ci zoo li hlau tab sis nkig nyiam nonmetals. Vim tias lawv nkig, lawv tuaj yeem tawg nyiam iav los yog crumble mus rau ib tug hmoov yog ntaus. Lwm yam khoom siv lub cev ntawm metalloids ntau dua sib txawv, suav nrog lawv cov ntsiab lus kub thiab melting, txawm tias tag nrho metalloids muaj nyob rau hauv cov khib nyiab ntawm chav tsev kub.

Plaub yam ntxwv ntawm metalloids yog dab tsi?
Lub cev lub cev ntawm metalloids yog raws li nram no: Metalloids muaj ib tug khoom lub xeev ntawm teeb meem. Feem ntau, metalloids muaj ib tug hlau luster. Metalloids muaj elasticity tsawg, lawv yog nkig heev. Middleweights yog cov ntsiab lus semi-coj, thiab lawv tso cai rau qhov nruab nrab kis ntawm tshav kub
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Qhov twg ntawm cov no yog tus yam ntxwv ntawm txhua yam muaj sia?
Cov yam ntxwv no yog lub koom haum ntawm tes, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution. Qee yam, xws li tus kab mob, pom tsuas yog qee yam ntawm cov yam ntxwv no thiab yog li ntawd, tsis muaj sia nyob
Dab tsi ntawm lub cev nta yog cov yam ntxwv ntawm cov ntug dej hiav txwv ntawm Texas?
Texas 'Gulf Coastal Plains yog sab hnub poob txuas ntxiv ntawm ntug hiav txwv tiaj tiaj txuas los ntawm Dej Hiav Txwv Atlantic mus dhau Rio Grande. Nws cov yam ntxwv dov mus rau toj roob hauv pes npog nrog kev loj hlob hnyav ntawm ntoo thuv thiab tawv ntoo txuas mus rau East Texas
Dab tsi yog 6 tus yam ntxwv ntawm txhua yam muaj sia?
Tshawb xyuas nrog cov tub ntxhais kawm no rau qhov yooj yim pom cov yam ntxwv ntawm cov khoom muaj sia: kev txav mus los (uas yuav tshwm sim sab hauv, lossis txawm tias nyob hauv qib cellular) kev loj hlob thiab kev loj hlob. teb rau stimuli. kev yug me nyuam. siv zog. cellular qauv
