Nitrogen (5 valence electrons) feem ntau daim ntawv peb daim ntawv cog lus thiab khaws cia ib leeg ib khub los sau nws octet.
Kuj tseem paub yog, pes tsawg daim ntawv cog lus nitrogen tuaj yeem tsim tau?
3 daim ntawv cog lus
Ib sab saum toj no, yuav ua li cas nitrogen muaj 4 daim ntawv cog lus? Yog koj saib daim duab saum toj no koj ua tau pom thaum ntawd nitrogen muaj ib tug zoo nqi (ib tug tsawg electron), nws tuaj yeem tsim 4 covalent daim ntawv cog lus . Nrog ib leeg, ob, lossis triple daim ntawv cog lus . Nws zoo ib yam li phosphorus hauv qhov no vim tias lawv ob leeg muaj tsib valence electrons (plaub thaum lawv muaj tus nqi zoo).
Ib yam li ib tug yuav nug, dab tsi Bonds ua nitrogen tsim?
Nitrogen atoms yuav tsim peb covalent bonds (tseem hu ua triple covalent ) nruab nrab ntawm ob lub atoms ntawm nitrogen vim hais tias txhua lub nitrogen atom xav tau peb electrons los sau nws lub plhaub sab nraud.
Puas muaj nitrogen muaj 5 daim ntawv cog lus?
Nitrogen ua tsis tau tiag ua 5 bonds , tshwj tsis yog koj suav 4 covalent daim ntawv cog lus thiab 1 ionic " daim ntawv cog lus ". Nquag a nitrogen atom forms 3 daim ntawv cog lus , tab sis thaum nitrogen atom muaj ib tug zoo nqi, nws yog deficiency nyob rau hauv ib tug electron, yog li nws tuaj yeem tsim ib qho ntxiv plaub covalent daim ntawv cog 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
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.
Muaj pes tsawg tus electrons raug muab faib rau hauv ob daim ntawv cog lus?
Hauv daim ntawv cog lus covalent ib khub ntawm electrons tau sib koom ntawm ob lub atoms 'txuas' los ntawm covalent daim ntawv cog lus. Yog li ib daim ntawv cog lus doublecovalent muaj ob khub ntawm electrons raug muab sib koom, yog li tag nrho plaub electrons
