Nyob rau hauv metallic bonding metallic bonding Strength of the bond
The atoms in metals have ib zog txaus nyiam ntawm lawv Ntau lub zog yuav tsum kov yeej nws. Yog li ntawd, cov hlau feem ntau muaj cov ntsiab lus kub kub, nrog tungsten (5828 K) siab heev. https://en.wikipedia.org › wiki › Metallic_bonding
Metallic bonding - Wikipedia
electrons tau delocalized thiab txav mus los ntawm cov nuclei. Thaum lub zog tawm ntawm cov hlau, cov nuclei hloov pauv, tab sis cov ntawv cog lus tsis tawg, muab cov hlau rau lawv cov yam ntxwv zoo.
Vim li cas hlau malleable?
Hlau yog malleable - lawv tuaj yeem khoov thiab zoo li tsis tawg. Qhov no yog vim lawv muaj cov txheej txheem ntawm cov atoms uas tuaj yeem xaub hla ib leeg thaum cov hlau yog khoov, hammered lossis nias.
Dab tsi yog hlau yog malleability?
Malleable hlau yuav khoov thiab ntswj ua ntau cov duab thaum cuam tshuam los ntawm rauj, hos cov hlau uas tsis yog-malleable tuaj yeem sib cais ua tej daim. Piv txwv ntawm malleable hlau yog kub, hlau, txhuas, tooj liab, nyiaj thiab txhuas.
Vim li cas cov hlau thiaj li tuaj yeem ua tau thiab zawm?
thoob plaws hauv cov qauv hlau uas cia cov atoms swb dhau ib leeg. Qhov zawv zawg no yog vim li cas cov hlau yog ductile thiab malleable.
Malleability cuam tshuam li cas rau hlau?
Malleability yog lub cev khoom ntawm cov hlau uas txhais tau tias lawv muaj peev xwm raug hammered, nias, lossis dov rau hauv cov ntawv nyias yam tsis muaj kev tawg. Hauv lwm lo lus, nws yog khoom ntawm cov hlau kom deform nyob rau hauv compression thiab coj mus rau ib tug tshiab zoo.
