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.

Yuav ua li cas yog daim ntawv cog lus sib txawv ntawm daim ntawv cog lus ionic?
Qhov sib txawv ntawm cov ionic thiab covalent daim ntawv cog lus yog tias covalent daim ntawv cog lus yog tsim thaum ob lub atoms sib koom electrons. Ionic bonds yog lub zog uas tuav ua ke electrostatic zog ntawm kev nyiam ntawm cov ions oppositely them. Ionic bonds muaj qhov sib txawv electronegativity ntau dua lossis sib npaug li 2
Dab tsi yog qhov txawv ntawm daim ntawv cog lus lub zog thiab daim ntawv cog lus dissociation zog?
Qhov sib txawv tseem ceeb ntawm kev sib txuas ntawm lub zog thiab lub zog bonddissociation yog tias lub zog sib txuas yog qhov nruab nrab ntawm lub zog xav tau los rhuav tshem tag nrho cov kev sib txuas ntawm tib ob hom atoms nyob rau hauv ib qho chaw sib txuas whereas daim ntawv cog lus dissociation zog yog tus nqi ntawm cov hluav taws xob xav tau los rhuav tshem ib qho kev sib koom ua ke inhomolysis
Puas yog daim ntawv cog lus hydrogen zoo ib yam li daim ntawv cog lus?
Hydrogen daim ntawv cog lus yog lub npe muab rau electrostatic kev sib cuam tshuam ntawm tus nqi zoo ntawm hydrogen atom thiab tus nqi tsis zoo ntawm oxygen atom ntawm ib qho chaw nyob sib ze. Covalent daim ntawv cog lus yog qhov sib cuam tshuam electrostatic ntawm ob lub atom hauv tib lub molecule
Muaj pes tsawg daim ntawv cog lus tuaj yeem tsim carbon atom thiab vim li cas?
plaub Tsis tas li ntawd, vim li cas nws tseem ceeb uas cov pa roj carbon tsim 4 daim ntawv cog lus? Cov pa roj carbon yog tib lub ntsiab uas ua tau daim ntawv thiaj li sib txawv tebchaw vim txhua carbon atom tau daim ntawv plaub tshuaj daim ntawv cog lus rau lwm cov atoms, thiab vim cov carbon atom tsuas yog txoj cai, me me kom haum rau qhov yooj yim raws li qhov chaw ntawm cov molecules loj heev.
Qhov tsawg tshaj plaws units ntawm ib daim ntawv cog lus ionic yog dab tsi?
Teb thiab piav qhia: Chav tsev me tshaj plaws ntawm daim ntawv cog lus ionic yog cov qauv qauv, uas yog qhov tsawg tshaj plaws ntawm cov atoms hauv cov qauv siv lead ua ionic
