Hom Tshuaj

  1. Hlau + Nonmetal -> ionic compound (feem ntau)
  2. Hlau + Polyatomic ion -> ionic compound (feem ntau)
  3. Nonmetal + Nonmetal -> covalent compound (feem ntau)
  4. Hydrogen + Nonmetal -> covalent compound (feem ntau)

Yog li ntawd, muaj pes tsawg hom ntawm compounds?

Muaj plaub hom kev sib xyaw , nyob ntawm seb cov atoms nyob rau hauv ua ke: molecules tuav ua ke los ntawm covalent bonds. ionic tshuaj sib xyaw tuav ua ke los ntawm ionic bonds. intermetallic tshuaj sib xyaw tuav ua ke los ntawm metallic bonds.

Ib yam li ntawd, koj ua li cas lub npe sib txuas lus nug? Rau molecular tshuaj sib xyaw , siv cov lej ua ntej ua ntej txhua lub ntsiab lus npe kom qhia tus naj npawb ntawm txhua lub ntsiab lus. Yog tias tsuas muaj ib qho atom ntawm lub ntsiab X, tsis muaj prefix yuav tsum tau ua ntej lub npe ntawm X. Siv lub ntsiab lus -ide tom qab lub caij npe rau Y. Yog X yog hlau, ces tus compound yog ionic; mus rau Kauj Ruam 3.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog 3 hom kev sib txuas?

Feem ntau hom kev sib xyaw poob rau hauv ib qho peb pawg hu ua ionic tshuaj sib xyaw , molecular tshuaj sib xyaw , los yog acids.

Ib tug Binary Compound

  • Hlau + Hlau = Metallic Compound.
  • Hlau + Tsis-Hlau = Ionic compound.
  • Tsis-Hlau + Tsis-Hom = Covalent compound.

Vim li cas cov pa oxygen yog diatomic molecule?

Oxygen feem ntau muaj raws li ib tug Diatomic molecule nyob rau hauv cov huab cua thaum nws tsis ua ke nrog lwm yam. Nws forms molecule ua O2 vim hais tias nyob rau hauv lub configuration, nws muaj nws qis zog theem thaum uncombined. Txhua yam khoom zoo li mus rau qib qis tshaj plaws uas ua tau. Oxygen muaj 6 valence electrons.
