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.
