Hlau Physical Properties:
- Lustrous (ci iab)
- Zoo conductors ntawm kub thiab hluav taws xob.
- Siab melting point.
- High ceev (hnyav rau lawv qhov loj me)
- Malleable (yuav tau hammered)
- Ductile (tuaj yeem kos rau hauv cov xov hlau)
- Feem ntau cov khoom nyob rau hauv chav tsev kub (ib qho kev zam yog mercury)
- Opaque raws li ib daim ntawv nyias (tsis pom los ntawm cov hlau)
Ntxiv mus, cov khoom ntawm hlau yog dab tsi?
Lub cev Cov Khoom Ntawm Cov Hlau Hlau yog lustrous, malleable, ductile, zoo conductors ntawm tshav kub thiab hluav taws xob. Lwm yam khoom suav nrog: Xeev: Hlau yog cov khib nyiab ntawm chav tsev kub tshwj tsis yog cov mercury, uas yog kua ntawm chav tsev kub (Gallium yog kua rau hnub kub).
Ib tug kuj yuav nug, dab tsi yog cov yam ntxwv ntawm ib tug nonmetal? Cov khoom uas feem ntau pom hauv nonmetals yog:
- rau ionic/covalent bonds.
- brittle thiab nonmalleable.
- qis melting / boiling point.
- Siab ionization zog thiab electronegativity.
- tsis zoo conductors ntawm tshav kub thiab hluav taws xob.
Ib sab ntawm no, dab tsi yog 5 metallic zog?
Lub cev muaj zog cuam tshuam nrog cov cim xim hlau muaj xws li hlau luster , ci ntsa iab tsos, siab ceev, siab thermal conductivity, thiab siab hluav taws xob conductivity. Cov hlau feem ntau yog tuaj yeem thiab ductile thiab tuaj yeem deformed yam tsis muaj kev tawg.
Dab tsi yog lub cev khoom ntawm hlau thiab tsis yog hlau?
Physical Properties of Nonmetals
- Nonmetals muaj lub zog ionization siab.
- Lawv muaj high electronegativities.
- Nonmetals yog insulators uas txhais tau hais tias lawv tsis zoo conductors ntawm hluav taws xob.
- Lawv npub, lawv tsis muaj luster zoo li hlau.
- Nonmetals yog cov tsis zoo conductors ntawm tshav kub.
- Lawv qaug zog heev thiab nkig.

Dab tsi yog 5 yam khoom ntawm cov khoom?
Cov khoom uas pom tau tias tuaj yeem tshawb pom nrog tsib qhov kev xav muaj xws li cov duab, xim, kev ntxhib los mos, hardness, luster, buoyancy, tsw, thiab saj. Cov khoom ntsuas muaj xws li qhov loj, ntim, qhov hnyav, qhov hnyav, qhov ntom, thiab qhov kub thiab txias
Yuav ua li cas koj thiaj paub tias ib yam dab tsi yog ib yam khoom dawb huv los yog sib tov?
1. Cov tshuaj dawb huv tsis tuaj yeem muab cais ua lwm yam teeb meem, thaum sib xyaw yog sib xyaw ntawm ob lossis ntau dua cov khoom ntshiab. 2. Cov khoom ntshiab muaj lub cev tsis tu ncua thiab tshuaj lom neeg, thaum cov khoom sib xyaw muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg (piv txwv li, qhov kub thiab txias)
Dab tsi yog 4 yam khoom ntawm cov hlau tsis muaj hlau?
Summary of Common Properties High ionization energies. High electronegativities. Cov thermal conductors tsis zoo. Cov hluav taws xob tsis zoo. Cov khoom tawg yooj yim - tsis tuaj yeem ua los yog ductile. Me me los yog tsis muaj xim hlau luster. Tau txais electrons yooj yim. Npub, tsis yog xim hlau-ci, txawm tias lawv yuav muaj xim
Dab tsi yog 4 yam khoom ntawm ib qho khoom?
Muaj plaub hom crystalline solids: molecular solids, network solids, ionic solids, thiab metallic solids. Ib qho khoom ntawm cov qauv atomic-theem thiab muaj pes tsawg leeg txiav txim siab ntau yam ntawm nws cov khoom macroscopic, xws li, piv txwv li, hluav taws xob thiab hluav taws xob conductivity, ntom, thiab solubility
Dab tsi yog cov khoom pov tseg ntawm cov saw hlau thauj khoom?
Yog tias muaj cov pa oxygen, kev ua pa ntawm tes hloov lub zog los ntawm ib qho molecule ntawm qabzib mus rau 38 molecules ntawm ATP, tso carbon dioxide thiab dej pov tseg
