Khoom siv: Germanium; Silicon; Tellurium; Boron
Yog li ntawd, koj tuaj yeem txheeb xyuas lub ntsiab lus uas yog metalloid li cas?
Txoj kev zoo tshaj plaws ntawm kev txiav txim yog tsis paub keeb yog a Metalloid yog los ntawm kev tshuaj xyuas yog tias muaj cov yam ntxwv ntawm cov hlau thiab cov hlau tsis muaj hlau tuaj yeem pom, yog tias ob qho tib si ces koj feem ntau yuav muaj qhov Metalloid element.
Tsuas muaj xya lub ntsiab lus cais:
- Boron.
- Silicon.
- Germanium.
- Arsenic.
- Antimony.
- Tellurium.
- Polonium.
Ib sab saum toj no, koj yuav ua li cas thiaj paub tias qee yam yog hlau lossis nonmetal? Raws li piv rau hlau , lawv muaj tsawg ntom thiab yuav yaj ntawm qhov kub thiab txias. Cov duab ntawm nonmetals hloov tsis tau yooj yim vim lawv yog brittle thiab yuav tawg. Cov ntsiab lus uas muaj cov khoom ntawm ob qho tib si hlau thiab nonmetals hu ua metalloids. Lawv tuaj yeem ci los yog dullland lawv cov duab yog hloov tau yooj yim.
Ib tug kuj yuav nug, dab tsi ua rau ib yam dab tsi metalloid?
Rau qhov feem ntau lees paub metalloids yog boron, silicon, germanium, arsenic, antimony, thiab tellurium. Tsib lub ntsiab lus tsis tshua muaj cais: carbon, aluminium, selenium, polonium, thiab astatin. Hom metalloids muaj metallicappearance, tab sis lawv yog nkig thiab tsuas yog ncaj ncees conductors ntawm hluav taws xob.
Dab tsi yog 8 metalloids?
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.

Yuav ua li cas koj txheeb xyuas lub kaum ntse ntse?
Qhov kev sib tshuam ntawm ob kab tau tsim lub kaum sab xis. Lub kaum sab xis yog ob lub kaum sab xis uas muaj kev sib raug zoo tshwj xeeb. Lub kaum sab xis khub hauv daim duab no muaj qhov ntsuas uas sib npaug 180 ° uas yog qhov ntsuas ntawm lub kaum sab xis. Lub kaum sab xis uas muaj qhov sib npaug ntawm 180 ° yog hu ua cov ces kaum ntxiv
Yuav ua li cas hom ntawm cov khoom raug txheeb xyuas los ntawm nws lub cev thiab tshuaj lom neeg lub zog?
Intensive zog, xws li ceev thiab xim, tsis nyob ntawm seb tus nqi ntawm cov khoom tam sim no. Lub cev lub cev tuaj yeem ntsuas yam tsis tau hloov cov khoom siv tshuaj lom neeg. Cov khoom siv tshuaj muaj peev xwm ntsuas tau los ntawm kev hloov cov tshuaj lom neeg tus kheej
Yuav ua li cas koj txheeb xyuas ib qho kev tawm tsam ua khub?
Txheeb xyuas ob khub ntawm kev ua-kev tawm dag zog. Siv cov cim 'ko taw A', 'ko taw C', thiab 'pob B' hauv koj cov lus. Nyem lub khawm kom pom cov lus teb. Thawj khub ntawm kev txiav txim siab-kev quab yuam ua khub yog: ko taw A thawb pob B mus rau sab xis; thiab pob B thawb ko taw A mus rau sab laug
Yuav ua li cas koj txheeb xyuas lub pob zeb igneous?
Cov kauj ruam hauv Kev Txheeb Xyuas: Txiav txim siab cov xim (qhia cov ntxhia muaj pes tsawg leeg) Txiav txim siab qhov kev ntxhib los mos (qhia txog keeb kwm txias) Phaneritic = cov nplej loj. Aphanitic = me nplej (me me dhau los txheeb xyuas qhov muag tsis pom) Porphyritic = cov nplej zoo sib xyaw nrog cov nplej loj. Vesicular = qhov. Glassy = iav zoo li
Yuav ua li cas koj txheeb xyuas lub monomer?
Monomers yog cov chav nyob ib leeg uas tsim los ua ib lub polymer. Peb tuaj yeem txiav txim siab seb lub monomer yog dab tsi los ntawm thawj zaug nrhiav qhov tsawg tshaj plaws rov ua qauv. Tom qab ntawd peb yuav tsum txiav txim siab yog tias tag nrho cov pa roj carbon atom hauv cov qauv rov ua dua tshiab muaj octet
