Qhov thib ob, dab tsi yog cov yam ntxwv ntawm D block element? Hlau xwm: raws li tus naj npawb ntawm electrons nyob rau hauv lub plhaub sab nraud yog tsawg heev piv txwv li tag nrho cov kev hloov cov ntsiab lus yog hlau. Lawv qhia cov yam ntxwv ntawm cov hlau xws li malleability thiab ductile nyob rau hauv cov xwm thiab tsim alloys nrog ob peb lwm yam hlau. Lawv kuj ua haujlwm zoo ntawm cov hluav taws xob thiab hluav taws xob.

Ua raws li qhov no, muaj pes tsawg lub ntsiab lus muaj nyob hauv D Block?

Muaj 40 d - thaiv cov ntsiab lus , 32, 36 lossis 40 hloov pauv hlau nyob ntawm seb koj suav pawg 3 lossis 12 li cov hlau hloov pauv, thiab 28 f- thaiv cov ntsiab lus (tsis muaj kev pom zoo thoob ntiaj teb ntawm qhov no).

D block txhais li cas?

d - thaiv . mus nyiag. kuv yuav mus d - thaiv tus me nyuam khau ntaub. Saib ntxiv cov lus nrog tib lub ntsiab lus: mus nyiag.
