Hauv cov tebchaw ionic, cov khoom siv hluav taws xob tau hloov pauv tag nrho ntawm ib lub atom mus rau lwm qhov kom lub cation-zoo them ion-thiab ib qho anion-negatively them ion-daim ntawv. … Tsis zoo li covalent compounds, tsis muaj ib yam li cov molecule ntawm cov ionic compound.
Qhov txawv ntawm ib lub molecule thiab ib qho ionic compound yog dab tsi?
Molecular compounds yog cov tshuaj ntshiab tsim thaum atoms txuas ua ke los ntawm kev sib koom ntawm electrons thaum ionic compounds yog tsim vim hloov ntawm electrons 2. Molecular compounds yog tsim los ntawm covalent Kev sib txuas thaum cov ionic compounds yog tsim los ntawm ionic bonding.
Puas yog tag nrho cov tshuaj molecules?
Thaum ob lossis ntau lub atoms sib koom ua ke, peb hu nws ua molecule. Thaum ob lossis ntau lub atoms ntawm cov ntsiab lus sib txawv koom ua ke, peb hu nws ua qhov sib xyaw. Txhua cov tebchaw yog molecules, tab sis tsis yog txhua lub molecules yog cov tebchaw.
5 piv txwv ntawm kev sib txuas yog dab tsi?
5 piv txwv ntawm kev sib txuas yog dab tsi?
- Sugar (sucrose - C12H22O11)
- rooj ntsev (sodium chloride - NaCl)
- dej (H2O)
- carbon dioxide (CO2)
- Sodium bicarbonate (baking soda - NaHCO3)
Ntshav yog molecule?
Ib yam zoo li cov lus ntsev (NaCl) yog cov khoom sib xyaw vim nws yog tsim los ntawm ntau tshaj ib hom (sodium thiab chlorine), tab sis nws yog tsis yog molecule vim tias daim ntawv cog lus uas tuav NaCl ua ke yog daim ntawv cog lus ionic. … Hom molecule no hu ua diatomic molecule, ib lub molecule ua los ntawm ob lub atom ntawm tib hom.
