Hlau tau piav raws li tuaj yeem (tuaj yeem raug ntaus rau hauv cov ntawv) thiab ductile (tuaj yeem rub tawm mus rau hauv cov xov hlau). Qhov no yog vim muaj peev xwm ntawm cov atoms dov ib leeg rau hauv txoj haujlwm tshiab yam tsis muaj kev tawg nws yog xim hlau daim ntawv cog lus.
Ua li no, puas yog tag nrho cov hlau malleable?
Tag nrho tus hlau yog tuaj yeem thiab ductile nrog rau kev zam ntawm mercury (Hg) raws li nws nyob hauv lub xeev ua kua thiab nws lub xeev tsis tuaj yeem hloov pauv. Lwm yam hlau muaj qhov no li bcoz lawv nyuaj li lawv nyob hauv lub xeev ruaj khov. Muaj qee yam hlau uas yog nyob rau hauv cov khoom tab sis tsis tawv (xws li sodium thiab potassium).
Ib tug kuj yuav nug, uas hlau yog malleable dua? Kub
Hauv qhov no, puas yog malleable hlau lossis nonmetal?
Malleability , lub peev xwm ntawm cov khoom siv rau hammered rau hauv ib daim ntawv (los ntawm Latin, malleus, rauj, yog ib qho khoom tseem ceeb ntawm hlau . Khoom tsis- hlau , np. pob zeb diamond, sulfur, iodine, tsis zoo li muaj cov cuab yeej no.
Dab tsi yog qhov malleability?
Malleability yog ib yam khoom muaj peev xwm deform nyob rau hauv siab (compressive stress). Yog tuaj yeem , cov khoom yuav raug flattened rau hauv nyias los ntawm hammering los yog dov. Malleable cov ntaub ntawv tuaj yeem flattened rau hauv cov nplooj hlau. Ntau cov hlau nrog siab kev ua tau zoo kuj muaj ductility siab.

Puas yog Phosphorus yog hlau lossis tsis yog hlau?
Phosphorus yog cov hlau tsis muaj hlau uas nyob hauv qab nitrogen hauv pawg 15 ntawm lub sijhawm. Cov khoom no muaj nyob rau hauv ntau hom, uas yog dawb thiab liab yog qhov zoo tshaj plaws paub. Dawb phosphorus yog twv yuav raug hu ntau exciting ntawm ob
Puas yog hlau yog hlau muaj zog?
Hlau yog cov khoom siv tshuaj thiab cov hlau. Nws yog qhov thib ob feem ntau hlau nyob hauv ntiaj teb, thiab feem ntau siv hlau. Nws ua rau ntau lub ntiaj teb lub hauv paus, thiab yog plaub feem ntau ntawm lub ntiaj teb lub pob zeb. Cov hlau siv ntau heev vim nws muaj zog thiab pheej yig
Puas yog malleable hlau lossis nonmetal lossis metalloid?
Hlau, Metalloids, thiab Nonmetals. Cov ntsiab lus tuaj yeem faib ua hlau, nonmetals, lossis metalloids. Cov hlau yog cov khoom siv hluav taws xob zoo ntawm cov cua sov thiab hluav taws xob, thiab tuaj yeem ua tau zoo (lawv tuaj yeem muab hammered rau hauv cov ntawv) thiab ductile (lawv tuaj yeem kos rau hauv cov hlau). Cov metalloids yog nruab nrab hauv lawv cov khoom
Cov hlau nplaum puas yuav lo rau galvanized hlau?
"Galvanized" tsuas yog txhais tau hais tias muaj cov zinc txheej sab nraud ntawm cov Hlau. Yog hais tias cov hlau ismagnetic pib nrog, ces nws tseem yuav sib nqus tom qab galvanizing. Txij li feem ntau tsis muaj laj thawj rau galvanizestainless hlau, cov lus teb yuav luag ib txwm "yog, galvanized steel yog sib nqus"
Puas yog alkali hlau thiab alkaline ntiaj teb hlau zoo ib yam?
Valance: Tag nrho cov alkali hlau muaj ib qho hluav taws xob nyob rau hauv lawv lub plhaub sab nraud thiab tag nrho cov alkaline ntiaj teb hlau muaj ob sab electrons. Yuav kom ua tiav cov kev teeb tsa muaj txiaj ntsig zoo, cov hlau alkali yuav tsum poob ib lub tshuab hluav taws xob (valence yog "ib"), thaum alkaline ntiaj teb hlau yuav tsum tshem tawm ob lub electrons (valence yog "ob")
