Tag nrho cov tebchaw yog molecules, tab sis tsis yog tag nrho cov molecules yog cov tebchaw. Hydrogen gas ( H2 ) yog ib qho molecule, tab sis tsis yog ib qho kev sib xyaw vim nws tsuas yog ua los ntawm ib qho khoom xwb. Dej ( H2O ) tuaj yeem hu ua molecule lossis cov khoom sib xyaw vim nws yog ua los ntawm hydrogen ( H ) thiab oxygen (O) atoms.

Dhau li ntawm no, uas yog cov molecules tab sis tsis tebchaw?

Lub compound yog ib qho molecule uas muaj tsawg kawg yog ob yam sib txawv. Tag nrho cov tebchaw yog molecules tab sis tsis yog tag nrho cov molecules yog cov tebchaw. Molecular hydrogen (H2), molecular oxygen (O2) thiab molecular nitrogen (N2) tsis yog cov tebchaw vim hais tias txhua yam yog tsim los ntawm ib lub caij.

Tsis tas li ntawd, dab tsi yog molecules thiab compounds? A molecule yog ib pab pawg los yog 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. 2. Kev txheeb ze. Tag nrho molecules tsis compounding.

Hauv qhov no, vim li cas tag nrho cov molecules tsis sib xyaw?

Txhua qhov sib xyaw yog molecules tab sis tsis yog tag nrho cov molecules yog tshuaj sib xyaw . yog tsis compounds vim hais tias txhua tus yog tsim los ntawm ib lub ntsiab. Dej (H2O), carbon dioxide (CO2) thiab methane (CH4) yog tshuaj sib xyaw vim txhua yam yog tsim los ntawm ntau tshaj ib lub ntsiab. A molecule yog tsim thaum ob los yog ntau tshaj atoms koom ua ke chemically.

Yog vim li cas dej yog molecule thiab tsis yog ib tug compound?

Dej yog a molecule vim nws muaj molecular daim ntawv cog lus. Dej kuj yog ib compound vim nws yog tsim los ntawm ntau tshaj ib hom khoom (oxygen thiab hydrogen). Oxygen hauv huab cua yog a molecule vim nws muaj molecular daim ntawv cog lus. Nws yog tsis yog compound vim nws yog tsim los ntawm cov atoms ntawm tsuas yog ib lub caij - oxygen.
