Electronegativity yog ib tug txheeb ze scale. Thaum twg tshuaj fluorine reacts nrog hlau, nws oxidizes hlau, thiab daim ntawv ib ionic daim ntawv cog lus . Txawm li cas los xij, thaum ob tshuaj fluorine atoms teb rau daim ntawv tus tshuaj fluorine molecule, ib tug purely covalent daim ntawv cog lus yog tsim.
Ntawm no, hom ntawv cog lus twg yog fluorine thiab fluorine?
Nrog rau lwm cov atoms, tshuaj fluorine daim ntawv yog polarcovalent daim ntawv cog lus los yog ionic daim ntawv cog lus . Feem ntau, covalent daim ntawv cog lus koom nrog tshuaj fluorine atoms yog ib leeg daim ntawv cog lus , txawm tias tsawg kawg yog ob qho piv txwv ntawm kev txiav txim siab dua daim ntawv cog lus muaj. Fluoride tuaj yeem ua raws li kev sib txuas ntawm ligand nruab nrab ntawm ob cov hlau hauv qee cov molecules complex.
Tsis tas li ntawd, hom kev sib cog lus dab tsi tshwm sim ntawm lithium thiab fluorine? Sawv cev ntawm ionic bonding ntawm lithium thiab fluorine ua form lithium fluoride . Lithium muaj ionization zog thiab yooj yim muab nws ib leeg valenceelectron rau a tshuaj fluorine atom, uas muaj ib tug zoo electronaffinity thiab txais cov electron uas tau pub los ntawm lub lithium atom.
Xav txog qhov no, hom ntawv cog lus twg yuav tsim ntawm ob lub fluorine atoms?
Cov hom ntawv cog lus uas feem ntau yuav yog tsim ntawm ob lub fluorine atoms yog nonpolar covalent daim ntawv cog lus . Hluav taws xob nruab nrab tus ob fluorine atoms sib koom nruab nrab lawv.
Cov ntsiab lus dab tsi tuaj yeem sib txuas nrog fluorine?
Fluorine (F2), muaj ob tshuaj fluorine atoms, ua ke nrog tag nrho lwm yam cov ntsiab lus Tsuas yog helium thiab neon los tsim ionic lossis covalentfluorides.

Cov qauv ntawm cov pa roj carbon atom cuam tshuam li cas rau hom kev sib cog lus nws tsim?
Carbon Bonding Vim hais tias nws muaj plaub valence electrons, carbon xav tau plaub electrons ntxiv rau nws cov txheej txheem zog. Los ntawm kev tsim plaub covalent bonds, carbon sib koom plaub khub ntawm electrons, yog li sau nws cov qib zog sab nraud. Cov pa roj carbon atom tuaj yeem tsim kev sib txuas nrog lwm cov pa roj carbon atom lossis nrog cov atom ntawm lwm cov ntsiab lus
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
Hom kev sib cog lus twg yog tsim thaum Lewis acid reacts nrog Lewis puag?
Sib koom covalent bond
Puas yuav fluorine tsim cov ntawv cog lus?
Nrog rau lwm cov atoms, fluorine tsim cov polarcovalent bonds los yog ionic bonds. Feem ntau, covalent bonds uas muaj fluorine atoms yog singlebonds, txawm hais tias tsawg kawg yog ob qho piv txwv ntawm kev txiav txim siab dua muaj nyob. Fluoride tuaj yeem ua raws li kev sib txuas ntawm ob lub hlau hauv qee cov molecules complex
