Elements thiab compounds yog cov homogeneous nkaus xwb thiab lawv muaj qhov sib txuas tas li thoob plaws. Elements thiab compounds tsis tuaj yeem muab cais rau hauv lawv cov khoom sib xws los ntawm kev siv lub cev. Cov tshuaj thiab kev sib tov yog ua los ntawm kev sib txawv cov ntsiab lus los yog txawv atoms.
Ib yam li ib tug yuav nug, dab tsi yog cov ntsiab lus thiab cov khoom sib xyaw ua ke?
Daim duab piv
| Compound | Element | |
|---|---|---|
| Txhais | Ib lub tebchaw muaj cov atom ntawm cov khoom sib txawv ntawm cov tshuaj sib xyaw ua ke hauv qhov sib piv ruaj khov. | Ib lub ntsiab yog cov tshuaj dawb huv uas ua los ntawm tib hom atom. |
Ib yam li ntawd, qhov zoo sib xws ntawm cov khoom thiab cov molecules yog dab tsi? Ob hom loj ntawm molecules muaj nyob, cov ntsiab lus thiab compounds. Ib keeb yog hom ntawm molecule suav nrog ntawm ib yam nkaus xwb ntawm atom. Cov lub ntsiab ntawm kub, piv txwv li, tsuas yog muaj ntawm kub atoms. Los ntawm sib piv , ib tug compound yog a molecule uas muaj ntawm ntau hom ntawm atoms lossis ntau hom ntawm cov ntsiab lus.
Yog li ntawd, dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm cov khoom thiab cov khoom sib txuas?
A compound muaj cov atom sib txawv cov ntsiab lus chemically ua ke ua ke nyob rau hauv ib tug taag ratio. Ib keeb yog ib hom tshuaj dawb huv ua los ntawm tib hom atom. Cov tshuaj muaj qhov sib txawv cov ntsiab lus nyob rau hauv ib tug taag ratio teem nyob rau hauv ib tug txhais lus los ntawm chemical bonds.
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm qhov sib xyaw thiab cov molecule?
A molecule yog ib pab pawg lossis pawg ntawm ob lossis ntau lub atoms tuav ua ke los ntawm cov khoom siv tshuaj. A compound yog ib yam khoom lossis khoom siv uas yog tsim los ntawm ob lossis ntau hom sib txawv ntawm cov ntsiab lus uas tau muab sib xyaw ua ke hauv ib qho kev faib ua feem. Tag nrho molecules tsis compounding. Tag nrho tshuaj sib xyaw yog molecules.
