Qhov sib txawv tseem ceeb ntawm cov molecule ntawm cov khoom thiab cov molecule ntawm cov khoom sib xyaw yog tias cov molecule ntawm lub ntsiab muaj tsuas yog ib hom atoms whereas lub molecule ntawm compound muaj ob los yog ntau hom atoms.
Ib lub molecule yog kev sib xyaw ntawm ob lossis ntau lub atoms. Peb tuaj yeem faib cov molecules rau hauv ntau pawg raws li tus naj npawb ntawm atoms, hom atoms, tshuaj sib txuas ntawm atoms, thiab lwm yam. Molecule ntawm lub caij thiab cov molecule ntawm compound yog ob pawg uas peb faib raws li hom atoms tam sim no nyob rau hauv lub molecule.
Molecule of Element yog dab tsi?
Molecule ntawm lub caij yog kev sib xyaw ntawm ob lossis ntau dua atoms ntawm tib hom. Qhov no txhais tau hais tias cov molecules no yog tsim tawm ntawm cov atoms ntawm tib yam tshuaj. Peb tuaj yeem faib lawv ntxiv raws li tus naj npawb ntawm cov atoms tam sim no hauv cov molecule. Piv txwv li, diatomic molecules ntawm lub caij muaj ob lub atoms ntawm tib yam tshuaj. Cov atoms ntawm cov molecules khi nrog ib leeg xwb los ntawm covalent tshuaj bonding.

Piv txwv ntawm Molecules ntawm Element
Qee yam piv txwv ntawm molecules ntawm lub caij muaj raws li hauv qab no:
- O2
- Cl2
- Br2
- H2
- O3
Molecule of Compound yog dab tsi?
Molecule ntawm compound yog ua ke ntawm ob los yog ntau tshaj atoms ntawm ntau hom. Qhov no txhais tau tias, cov molecules no muaj kev sib txawv ntawm cov tshuaj sib txawv. Ib yam li molecule ntawm lub caij, peb tuaj yeem faib lawv ntxiv raws li tus naj npawb ntawm cov atoms tam sim no hauv cov molecule. Cov tshuaj sib txuas ntawm cov atoms tuaj yeem yog covalent bonds lossis ionic bonds. Ionic bonds ib txwm tsim ntawm cations (positive ions) thiab anions (tsis zoo ions). Yog li ntawd, ionic bonds ib txwm tsim ntawm ob yam tshuaj sib txawv.

Piv txwv ntawm Molecules ntawm Compound
Qee yam piv txwv ntawm molecules ntawm compound yog raws li nram no:
- H2O, NH3, SO3 yog molecules ntawm compound nrog covalent kev sib raug zoo.
- NaCl, KCl yog cov molecules ntawm compound nrog ionic bonding.
Qhov txawv ntawm Molecule ntawm Element thiab Molecule ntawm Compound?
Molecule ntawm lub caij yog kev sib xyaw ntawm ob lossis ntau dua atoms ntawm tib hom. Nws muaj atoms ntawm ib qho tshuaj lom neeg. Ntawm qhov tod tes, cov molecule ntawm compound yog kev sib xyaw ntawm ob lossis ntau lub atoms ntawm ntau hom. Nws muaj atoms ntawm ob los yog ntau tshaj cov tshuaj. Qhov no yog qhov sib txawv tseem ceeb ntawm molecule ntawm lub caij thiab molecule ntawm compound. Ntxiv mus, lub molecule ntawm lub caij muaj covalent tshuaj bonds tab sis, lub molecule ntawm compound muaj xws li covalent los yog ionic tshuaj bonds.
Summary – Molecule of Element vs Molecule of Compound
Molecule ntawm cov khoom thiab cov khoom sib xyaw yog ob pawg sib txawv ntawm cov molecules. Qhov txawv ntawm molecule ntawm lub caij thiab molecule ntawm compound yog hais tias lub molecule ntawm lub ntsiab muaj tsuas yog ib hom ntawm atoms whereas lub molecule ntawm compound muaj ob los yog ntau hom atoms.
