Ionic daim ntawv cog lus , kuj hu ua electrovalent daim ntawv cog lus , hom kev sib txuas tsim los ntawm electrostatic attraction ntawm oppositely them ions hauv tshuaj compound . Xws li ib daim ntawv cog lus Thaum lub valence (sab nraud) electrons ntawm ib lub atom raug xa mus tas li mus rau lwm lub atom.

Nyob rau hauv kev hwm rau qhov no, yuav ua li cas lub ionic daim ntawv cog lus yog tsim?

Ionic kev sib txuas yog qhov kev hloov pauv tag nrho ntawm valence electron (s) ntawm atoms. Nws yog ib hom tshuaj daim ntawv cog lus uas generates ob oppositely them ions . Hauv ionic daim ntawv cog lus , cov hlau poob electrons los ua ib tug zoo charged cation, whereas lub nonmetal txais cov electrons los ua ib tug negatively charged anion.

Ib yam li ntawd, dab tsi yog txhais los ntawm ionic bond? ionic daim ntawv cog lus . npe. Cov txhais ntawm ionic daim ntawv cog lus yog thaum tus nqi zoo ion forms ib daim ntawv cog lus nrog tus nqi tsis zoo ions thiab ib lub atom hloov electrons mus rau lwm tus. Ib qho piv txwv ntawm ib ionic daim ntawv cog lus yog tshuaj compound Sodium Chloride.

Ntxiv mus, dab tsi yog ib qho ionic compound thiab nws tsim li cas?

Ib ionic compound yog tsim los ntawm tag nrho cov hloov ntawm electrons los ntawm ib tug hlau mus rau ib tug nonmetal thiab qhov tshwm sim ions tau ua tiav ib qho octet. Cov protons tsis hloov. Hlau atoms nyob rau hauv pawg 1-3 poob electrons rau non-metal atoms nrog 5-7 electrons uas ploj lawm nyob rau hauv sab nrauv.

Dab tsi ua rau ionic compound?

Ionic compounds yog tshuaj sib xyaw ua los ntawm ions . Cov no ions yog atoms uas nce lossis poob electrons, muab lawv tus nqi zoo lossis tsis zoo. Cov hlau zoo li poob electrons, yog li lawv dhau los ua cations thiab muaj cov txiaj ntsig zoo. Nonmetals zoo li tau txais electrons, tsim cov anions uas muaj tus nqi tsis zoo.
