A metalloid yog ib keeb uas muaj cov khoom ntawm cov hlau thiab cov hlau tsis yog hlau, thiab yog li ntawd nyuaj rau kev faib ua cov hlau los yog nonmetal. Boron, silicon, germanium, arsenic, antimony, thiab tellurium feem ntau lees paub tias yog metalloids.
Ib yam li ntawd ib tug yuav nug, puas yog lub hauv paus ntawm metalloid?
Cov metalloids ; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) thiab astatine (At) yog cov cov ntsiab lus pom nyob rau hauv cov kauj ruam zoo li kab ntawm cov hlau thiab cov hlau tsis muaj hlau ntawm lub rooj zaum. Metalloids muaj cov khoom ntawm cov hlau thiab tsis yog hlau.
Ib sab saum toj, dab tsi yog 8 metalloids? Cov yim cov ntsiab lus cais raws li metalloids yog boron, silicon, germanium, arsenic, antimony, tellurium, astatine, thiab polonium. Metalloids tshwm sim raws kab pheeb ces kaum-kauj ruam ntawm cov hlau thiab tsis yog hlau.
Tom qab ntawd, ib tug kuj yuav nug, ua li cas koj txheeb xyuas lub metalloid?
Cov metalloids yog ib pawg ntawm cov ntsiab lus nyob rau hauv lub sij hawm. 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.
Lub ntsiab lus twg yog qhov piv txwv ntawm metalloid?
Arsenic

Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Dab tsi yog peb lub hauv paus ntsiab lus uas tso cai rau lub tshuab hluav taws xob ua haujlwm?
Lub tshuab hluav taws xob ua haujlwm ntawm peb lub cev sib txawv: hlau nplaum, electrostatics thiab piezoelectricity. Txog tam sim no, feem ntau yog cov hlau nplaum. Hauv kev sib nqus motors, magnetic teb yog tsim nyob rau hauv ob lub rotor thiab stator
Dab tsi yog rau lub ntsiab lus tseem ceeb ntawm thaj chaw raws li tau hais los ntawm National Council rau Geographic Education?
Txheeb xyuas thiab siv rau qhov tseem ceeb ntawm thaj chaw (piv txwv li, lub ntiaj teb nyob rau hauv cov ntsiab lus spatial, qhov chaw thiab cheeb tsam, lub cev, tib neeg lub cev, ib puag ncig thiab tib neeg, thiab siv thaj chaw), suav nrog cov ntsiab lus tshwj xeeb rau txhua lub ntsiab lus
Cov organic tebchaw tau txais lawv lub npe Li cas lo lus muaj feem xyuam rau nws lub ntsiab lus li cas?
Lo lus hais txog nws lub ntsiab lus li cas? Organic Compounds tau txais nws lub npe los ntawm tus lej ntawm cov ntawv cog lus carbon. Lo lus muaj feem xyuam rau lub ntsiab lus vim hais tias nws yuav tsum tau ua nrog bonds nyob rau hauv carbon atoms nyob rau hauv cov organic tebchaw
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
