Lawv yog malleable, uas txhais tau tias lawv ua tau beg thiab zoo li yooj yim . Hauv cov hlau ntshiab , cov atoms tau teem rau hauv cov khaubncaws sab nraud povtseg, thiab thaum lub zog siv rau cov hlau (xws li raug ntaus nrog rauj), cov txheej ntawm cov hlau atoms. ua tau swb dua ib leeg, muab cov hlau ua ib qho tshiab.
Ua li no, vim li cas cov hlau tau yooj yim zoo li?
Hlau yog malleable - lawv tuaj yeem khoov thiab zoo li tus tsis tawg. Qhov no yog vim hais tias lawv muaj cov txheej ntawm atoms uas yuav swb dua ib leeg thaum lub hlau yog khoov, hammered los yog nias.
Ib yam li ntawd, vim li cas qee cov hlau softer dua lwm tus? Cua sov a hlau zoo li co cov atoms mus rau hauv ib tug ntau dua kev npaj - txo tus naj npawb ntawm grain ciam teb, thiab thiaj li ua tus hlau softer . Banging lub hlau nyob ib ncig ntawm thaum nws txias zoo li tsim tau ntau cov nplej me me. Kev ua haujlwm txias yog li ua rau a hlau nyuaj dua.
Ib yam li ntawd, tib neeg nug, vim li cas nws yooj yim dua los hloov cov duab ntawm cov hlau ntshiab dua li cov hlau?
A hlau ntshiab muaj zoo tib yam atoms teem nyob rau hauv tsis tu ncua txheej. Cov khaubncaws sab nraud povtseg ntawm ib leeg yooj yim. Cov hlau nplaum yog nyuaj dua thiab muaj zog vim qhov sib txawv ntawm cov atoms sib xyaw hlau ua rau cov atomic txheej tsis tu ncua, yog li lawv tsis tuaj yeem swb yooj yim.
Cov hlau ntshiab yog dab tsi?
Cov hlau ntshiab yog ib yam khoom uas muaj cov atoms ntawm ib hom hlau, xws li txhuas, kub, tooj liab, txhuas los yog zinc. Ntau hlau muaj cov khoom muaj txiaj ntsig zoo, xws li ua cov khoom siv hluav taws xob zoo. Txawm li cas los xij, feem ntau ntawm hlau yog mos heev thiab malleable siv. hauv lawv dawb huv daim ntawv.

Cov khoom puas tuaj yeem muab cais ua cov khoom yooj yim?
Cov ntsiab lus tsis tuaj yeem tawg mus rau hauv cov khoom yooj yim. Ib yam li ntawd, ib lub ntsiab lus tsis tuaj yeem hloov pauv mus rau hauv ib lub caij sib txawv. Cov khoom siv tshuaj yog qhov yooj yim ntawm cov khoom
Yam khoom twg tuaj yeem pom tau yooj yim?
Cov cuab yeej ntawm lub cev yog cov yam ntxwv ntawm cov khoom uas tuaj yeem soj ntsuam lossis ntsuas yam tsis hloov tus kheej ntawm cov khoom. Lub cev muaj xws li xim, ntom, hardness, thiab melting thiab boiling ntsiab lus. Cov cuab yeej Achemical piav qhia txog lub peev xwm ntawm cov khoom siv los hloov pauv tshuaj lom neeg
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Vim li cas cov lus ntsev tau yooj yim yaj hauv dej?
Lub rooj ntsev yaj nyob rau hauv dej vim hais tias cov polar dej molecules nyiam ob qho tib si zoo nqi sodium ions thiab cov tsis zoo chloride ions. Lwm cov ntsev yaj hauv dej, ib yam nkaus, tab sis qee qhov lawv yaj yooj yim dua lwm tus
Vim li cas cov alloys nyuaj dua li cov hlau ntshiab BBC Bitesize?
Hauv ib qho alloy, muaj cov atoms sib txawv. Cov atoms me los yog loj dua distort cov txheej ntawm atoms nyob rau hauv cov hlau ntshiab. Qhov no txhais tau hais tias yuav tsum muaj lub zog ntau dua rau cov khaubncaws sab nraud povtseg rau ib leeg. Cov alloy yog ib qho nyuaj thiab muaj zog dua li cov hlau ntshiab
