Cov ntsiab lus hauv cov teeb no (10)
- Cov qauv yooj yim tshaj plaws rau covalent compound yog nws.
- Lub anion tsim los ntawm cov pa atom yog hu ua an.
- Fe O yog lub npe hu ua hlau (III) oxide vim nws muaj.
- Nws yog ua tau rau cov sib txawv covalent tebchaw kom muaj tib empirical mis vim hais tias cov qauv empirical sawv cev.
Ntawm no, dab tsi yog tus qauv rau covalent compound?
Lub npe binary (ob lub ntsiab lus) covalent compounds zoo ib yam li lub npe yooj yim ionic tshuaj sib xyaw . Thawj lub hauv paus qauv tsuas yog sau npe siv lub npe ntawm lub caij. Lub caij thib ob yog lub npe los ntawm kev noj lub qia ntawm lub npe lub npe thiab ntxiv cov lus kawg -ide.
Tom qab ntawd, lo lus nug yog, koj sau cov qauv rau cov tebchaw li cas? Txhawm rau sau cov qauv empirical rau ib qho ionic compound:
- Txheeb xyuas qhov cation.
- Sau tus qauv kom raug thiab them rau cation.
- Txheeb xyuas cov anion.
- Sau cov mis kom raug thiab them rau cov anion.
- Muab cov cation thiab anion los ua ib qho hluav taws xob nruab nrab.
Kuj paub yog, piv txwv li covalent compound yog dab tsi?
A covalent daim ntawv cog lus ntawm ob qho tsis yog hlau los ntawm kev sib koom electrons, yog li ib qho piv txwv tuaj yeem yog "Dej, H2O" raws li nws yog tsim los ntawm kev sib koom ntawm electrons ntawm hydrogen thiab oxygen (uas yog ob qho tib si tsis yog hlau). Thiab lwm tus piv txwv ntawm covalent "Carbon dioxide, CO2".
Dab tsi yog lwm lub npe rau covalent compound?
A covalent daim ntawv cog lus, tseem hu ua ib daim ntawv cog lus molecular, yog ib daim ntawv cog lus tshuaj uas koom nrog kev sib koom ntawm cov khoom hluav taws xob ntawm cov atoms. Cov khub hluav taws xob no hu ua cov khub sib koom lossis cov khub sib koom ua ke, thiab qhov sib npaug ruaj khov ntawm kev ntxim nyiam thiab ntxim nyiam ntawm cov atoms, thaum lawv sib koom electrons, hu ua covalent kev sib raug zoo.
