Raws li nyob rau hauv carbon dioxide molecule ob carbon zoo li oxygen tau ua tiav lawv cov octet bysharing electrons. #Ib leeg carbon muaj 4 valency thiab oxygen muaj 2. Nws yog + ntxiv 4. Raws li nws yog bounded los ntawm 2 oxygen atoms uas muaj -2 nqi ntawm txhua.

Tsis tas li ntawd, Valency ntawm carbon yog dab tsi?

Tetra- valency ntawm cov pa roj carbon muaj tus lej atomic ntawm 6, lub ntsiab lus txhua carbon atom muaj tag nrho ntawm 6 electrons. Ob tug yog nyob rau hauv lub tiav puab orbit, thaum plaub electrons pom nyob rau hauv lub atom lub sab hnub poob orbit.

Ib yam li ntawd, vim li cas Valency ntawm carbon yog 2? Teb: ( 2 ) raws li plaub valence electrons ntawm txhua carbon atom los ntawm nws lub plhaub sab nraud yog koom nrog covalent bonding soits valency yog 4 (Tetravalent). valency rau carbon yuav nyob twj ywm tib yam li 4. vim nws yog sib koom nwsselectrons.

Ntawm no, dab tsi yog qhov Valency ntawm oxygen?

Cov valency ntawm oxygen yog -2. Qhov no txhais tau tias oxygen yuav tsum tau nce los yog faib ob electrons forstability.

Vim li cas carbon Valency 4?

Vim a carbon atom muaj plaub electrons nyob rau hauv nws sab nraud valence plhaub. Yog li, nws xav tau plaub lub electrons ntxiv kom ua tiav nws cov octet. A carbon atom ua kom tiav nws octet tsuas yog sib qhia nws valence electrons nrog lwm cov atoms. Raws li qhov tshwm sim, a carbon atom tsim plaub covalent bonds los ntawm kev sib koom valence electrons nrog lwm cov atoms.
