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.
