Nyob hauv chemistry, tetravalence yog lub xeev ntawm ib lub atom nrog plaub lub electrons muaj rau covalent tshuaj bonding nyob rau hauv nws valenceIb qho piv txwv yog methane: cov tetravalent carbon atom tsim ib daim ntawv cogalent nrog plaub hydrogen atoms. Cov pa roj carbon atom hu ua tetravalent vim nws tsim 4 covalent bonds.
Tus piv txwv tetravalent yog dab tsi?
Tetravalent cov ntsiab lus yog cov ntsiab lus uas muaj qhov muaj txiaj ntsig ntawm plaub piv txwv li muaj plaub lub tshuab hluav taws xob hauv lub plhaub sab nraud. Qee qhov piv txwv yog cov ntsiab lus ntawm pawg 14 xws li carbon, silicon, germanium thiab lwm yam. Vam tias qhov no yuav pab tau.
Vim li cas cov pa roj carbon hu ua tetravalent?
Cov pa roj carbon atom muaj plaub lub electrons hauv nws lub plhaub sab nraud. Cov pa roj carbon atoms tuaj yeem ua tiav cov pa roj hluav taws xob tsis zoo los ntawm kev sib koom ntawm cov hluav taws xob, yog li cov pa roj carbon ib txwm ua cov ntawv cog lus. … Carbon suav hais tias yog tetravalent vim nws muaj plaub lub electrons nyob rau hauv nws sab nraud orbital.
tus cwj pwm tetravalent yog dab tsi?
Nws yog tus sawv cev los ntawm lub cim C thiab nws tus lej atomic yog 6. … Yog li, carbon yog tetravalent (Nws txhais tau tias qhov muaj txiaj ntsig ntawm cov pa roj carbon yog 4.) thiab tuaj yeem tsim 4 covalent. bonds nrog tsis tsuas yog lwm cov atoms tab sis lwm yam carbon atoms thiab. Qhov no yog hu ua tetravalency ntawm carbon.
Koj txhais li cas los ntawm tetravalent daim ntawv cog lus?
Teb: Daim ntawv cog lus tetravalent yog ib qho uas cov pa roj carbon atom qhia nws cov electrons nrog lwm lub atom. Feem ntau, covalent daim ntawv cog lus koom nrog. 4 electrons.
