HOM MOLECULES

Muaj xya diatomiceElements: Hydrogen (H2Nitrogen (N2), Oxygen (O2), Fluorine ((F2), chlorine ((Cl2), --Iodine ((I2) thiab Bromine (Br2) Cov xya lub ntsiab lus no muaj zog heev uas lawv tuaj yeem pom muaj feem ntau txuas nrog lwm lub atom ntawm tib hom.

Hauv qhov no, 3 qhov piv txwv ntawm molecules yog dab tsi?

Piv txwv ntawm Molecules:

  • Cov pa roj carbon dioxide - CO2
  • Dej - H2O.
  • Oxygen peb ua pa rau hauv peb lub ntsws - O2
  • Qab Zib - C12H22O11
  • Glucose - C6H12O6
  • Nitrous oxide - "Laughing gas" - N2O.
  • Acetic acid - ib feem ntawm vinegar - CH3COOH. Txuas Txuas: Piv txwv. Piv txwv science.

Ib yam li ntawd, piv txwv ntawm molecules yog dab tsi? Piv txwv ntawm Molecules

  • H2O (dej)
  • N2 (nitrogen)
  • O3 (ozone)
  • Calcium oxide (CaO)
  • C6H12O6 (glucose, ib hom qab zib)
  • NaCl (lub rooj ntsev)

Tsis tas li ntawd, muaj pes tsawg hom molecules muaj?

Muaj peb hom molecules uas yog lub ntsiab molecule , lub compound molecule & qhov sib tov.

Dab tsi yog qhov feem ntau molecule?

hydrogen
