Txhua lub plhaub valence puv, yog li qhov no yog qhov lees paub Lewis electron dot diagram dot diagram Lub Lewis qauv tau muaj npe tom qab Gilbert N. Lewis, uas tau qhia hauv nws tsab xov xwm 1916. Lub Atom thiab Molecule. Cov qauv Lewis txuas ntxiv lub tswv yim ntawm daim duab duab hluav taws xob los ntawm kev ntxiv cov kab nruab nrab ntawm cov atoms los sawv cev rau cov khub sib koom hauv cov ntawv cog lus tshuaj. https://en.wikipedia.org › wiki › Lewis_structure
Lewis qauv - Wikipedia
. Yog tias peb yuav siv cov kab los sawv cev cov ntawv cog lus, peb yuav siv ob kab ntawm C thiab O atoms: Daim ntawv cog lus ntawm C thiab O atoms yog ob daim ntawv cog lus.
Puas C thiab O puas tsim daim ntawv cog lus?
A carbon–oxygen bond is a polar covalent bond between carbon and oxygen. Oxygen muaj 6 valence electrons thiab nyiam los faib ob lub electrons hauv kev sib txuas nrog carbon, tawm hauv 4 nonbonding electrons nyob rau hauv 2 ib leeg khub: O: los yog muab ob khub electrons los ua pawg carbonyl functional.
Puas yog C thiab O ionic lossis covalent?
Txij li kev sib koom ntawm cov ntaub ntawv electrons covalent daim ntawv cog lus, carbon monoxide yog covalent compound.
C thiab O daim ntawv cog lus dab tsi?
Ntawd yog, ib lub atom yuav tsum tuaj yeem pub cov khoom siv hluav taws xob thaum lwm tus yuav tsum muaj peev xwm lees txais cov electrons. Ntawm no, ob qho tib si carbon thiab oxygen tsis yog hlau. Cov hlau tsis yog hlau feem ntau tsim covalent bonds vim lawv tsis yooj yim pub electrons. Yog li carbon thiaboxygen ua ke los ntawm covalent bonding.
Puas yog daim ntawv cog lus?
Ob daim ntawv cog lus tsim ntawm ob lub pa oxygen atoms vim tias oxygen xav tau ob qho khoom siv hluav taws xob los ua kom nws lub plhaub sab nraud. … Cov kev sib cog lus covalent ntawm hydrogen thiab oxygen atoms hauv dej yog polar covalent bonds.
