Cov hlau yog ductile es tsis txhob nkig vim lawv muaj daim ntawv cog lus hloov tau. Ductility txhais tau tias muaj peev xwm ntawm a hlau yuav tsum tau kos rau hauv cov xov hlau. A hlau muaj daim ntawv cog lus hloov tau. Qhov kev hloov pauv no tso cai rau lawv ua ductile.

Ib yam li ntawd, vim li cas cov hlau tsis muaj nkig?

Vim hais tias cov delocalised electrons yog dawb txav mus. Cov delocalised electrons yog dawb txav mus thoob plaws hauv cov hlau loj loj lattice, yog li ib txheej ntawm hlau ions swb dua lwm tus, cov electrons tuaj yeem txav mus ua kom tag nrho cov qauv sib txuas ua ke.

Ib tug kuj nug, yam khoom twg muaj tseeb rau cov hlau? Lub cev Cov khoom ntawm 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).

Cov yam ntxwv twg ntawm cov hlau atom pab piav qhia vim li cas Valence?

Yam ntxwv ntawm hlau atoms pab piav qhia vim li cas valence electrons hauv a hlau yog delocalized? Hlau atoms yog loj thiab muaj siab electronegativities. Hlau atoms yog me me thiab muaj tsawg electronegativities. Hlau atoms yog loj thiab muaj tsawg electronegativities.

Qhov laj thawj twg zoo tshaj piav qhia tias yog vim li cas cov hlau tuaj yeem ua tau?

Cov khoom ntawm Hlau Lawv cuam tshuam lub teeb vim yog cov dawb electrons. Hlau yog malleable vim tias nws cov atoms tuaj yeem xaub hla ib leeg yam tsis muaj kev puas tsuaj rau nws cov qauv.
