Teb thiab Kev 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.

Ntawm no, dab tsi yog qhov tsawg tshaj plaws ntawm daim ntawv cog lus ionic?

Cov me me particle hauv ib ionic compound yog ion thiab me me particle hauv covalent compound yog molecules. Lub xeev ib txwm (ntawm chav tsev kub) ntawm ib ionic compound yog khoom thiab lub xeev ib txwm muaj covalent compound yog kua/gas.

Tsis tas li ntawd, qhov tsawg tshaj plaws chav tsev ntawm covalent compound yog dab tsi? Covalent compounds muaj ob los yog ntau tshaj cov khoom nonmetallic tuav ua ke los ntawm covalent bonds , nyob rau hauv uas atoms sib koom ua khub ntawm valence electrons. Ib qho molecule yog qhov tsawg tshaj plaws particle ua a covalent compound uas tseem muaj cov khoom ntawm cov compound.

Tom qab ntawd, dab tsi yog ib chav tsev nyob hauv daim ntawv cog lus ionic?

A formula unit hauv chemistry yog empirical qauv ntawm tej ionic los yog covalent network solid compound siv los ua ib qho chaw ywj pheej rau kev suav stoichiometric. Nws yog tus lej qis tshaj plaws ntawm tus lej ions sawv cev hauv ib ionic compound.

Dab tsi yog txhais los ntawm ionic bond?

Kev txhais lus rau ionic bond ionic bond . [ī-ŏn'ĭk] A chemical daim ntawv cog lus tsim ntawm ob ions nrog cov nqi sib txawv. Ionic daim ntawv cog lus daim ntawv thaum ib lub atom muab ib lossis ntau dua electrons mus rau lwm lub atom. Cov no daim ntawv cog lus tuaj yeem tsim ntawm ib khub ntawm atoms lossis nruab nrab ntawm cov molecules thiab yog hom daim ntawv cog lus pom nyob rau hauv ntsev.

Lub koom haum loj yog dab tsi, los ntawm qhov tsawg tshaj plaws mus rau qhov loj, uas cov kws tshawb fawb feem ntau kawm? 6 theem sib txawv ntawm lub koom haum uas ecologists nquag kawm yog hom, pejxeem, zej zog, ecosystem, thiab biome

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
