covalent

Yog li ntawd, hom kev sib cog lus dab tsi yog feem ntau hauv cov zaub mov?

Chemical bonds nyob rau hauv cov zaub mov muaj plaub hom: covalent , ionic, metallic, los yog Van der Waals, nrog covalent thiab ionic daim ntawv cog lus feem ntau. Ob lossis ntau dua ntawm cov nyiaj no tuaj yeem sib koom ua ke hauv ntau cov zaub mov.

Tsis tas li ntawd, 4 hom kev sib cog lus yog dab tsi? 4 Hom Tshuaj Bonds

  • 1 Ionic daim ntawv cog lus. Ionic bonding cuam tshuam nrog kev hloov ntawm ib qho hluav taws xob, yog li ib lub atom tau txais ib qho hluav taws xob thaum ib lub atom poob ib qho hluav taws xob.
  • 2 Covalent bond. Kev sib cog lus ntau tshaj plaws hauv cov organic molecules, covalent daim ntawv cog lus koom nrog kev sib koom ntawm electrons ntawm ob lub atoms.
  • 3 Polar daim ntawv cog lus.

Ib yam li ntawd ib tug yuav nug, dab tsi yog qhov kev sib raug zoo tshaj plaws hauv chemistry?

2/ yog covalent daim ntawv cog lus muaj siab polarity ntxiv rau siab molecular mass thiab symmetrical uas pab nyob rau hauv packing ces covalent daim ntawv cog lus ntawm cov khoom yuav muaj zog dua.

Cov khoom siv tshuaj muaj zog tshaj plaws yog covalent daim ntawv cog lus.

  • Dab tsi yog daim ntawv cog lus tshuaj hu ua tsim los ntawm kev sib koom ntawm electrons?
  • Ib qho chaw puas tuaj yeem muaj ntau tshaj ib daim ntawv cog lus?

Cov ntawv cog lus dab tsi tuaj yeem muaj cov pob zeb hauv pob zeb?

Hom Bonding hauv Crystals

  • Ionic Bonds. Thaum cov ionic muaju tsim, cov electrons dhia lawv lub orbits mus rau kev sib raug zoo nrog cov khoom txhawb nqa atom.
  • Covalent Bonds. Covalent daim ntawv cog lus, raws li lub npe qhia, yog cov qauv siv lead ua uas cov electrons tsis tawm ntawm lawv lub orbits.
  • Van der Waals Bonds.
  • Hydrogen Bonds.
  • Hlau Bonds.
