Loj ionic cov qauv. Cov ions nyob rau hauv ib tug compound, xws li sodium chloride, yog teem hauv a loj ionic qauv (tseem hu ua a loj ionic lattice ). Qhov no txhais tau tias uas ionic cov tebchaw muaj cov ntsiab lus melting siab thiab cov ntsiab lus boiling. Khoom ionic tshuaj sib xyaw ua tsis ua hluav taws xob vim lub ions yog tuav khov kho nyob rau hauv qhov chaw

Tsuas yog li ntawd, yuav ua li cas loj heev ionic lattice tsim?

Ib ionic compound yog a loj heev qauv ntawm ions . Cov ions muaj ib tug li niaj zaus, rov hais dua kev npaj hu ua ib ionic txheej . Cov daim kab xev yog tsim vim cov ions sib nyiam thiab daim ntawv ib txwm qauv nrog oppositely them ions nyob ib sab.

Ib tug kuj yuav nug, yog sodium chloride ib tug loj heev ionic lattice? Cov qauv ntawm ib yam ionic khoom - sodium chloride Sodium chloride hmoov yog coj raws li ib txwm ionic compound. Cov tshuaj zoo li no suav nrog a loj (tsis muaj hnub rov rov qab los) daim kab xev ntawm ions . Yog li sodium chloride (thiab lwm yam ionic compound) tau piav qhia tias muaj a loj heev ionic qauv.

Tib neeg kuj nug, puas yog pob zeb diamond loj heev ionic lattice?

Qauv thiab kev sib raug zoo Pob zeb diamond muaj ib loj covalent qauv nyob rau hauv uas: txhua carbon atom yog koom rau plaub lwm carbon atoms los ntawm covalent bonds. cov pa roj carbon atoms muaj ib txwm daim kab xev kev npaj. tsis muaj electrons dawb.

Puas yog tag nrho cov ionic compounds tsim cov lattices loj?

Ionic compounds muaj cov qauv tsis tu ncua, hu ua loj heev ionic lattices . Hauv ib loj ionic lattice , muaj yog muaj zog electrostatic zog ntawm attraction ua nyob rau hauv tag nrho cov lus qhia ntawm tus oppositely them ions . Cov qauv thiab kev sib txuas ntawm ionic compounds piav lawv tej khoom.
