1 Teb. Ionic bonds tshwm sim los ntawm kev sib nrig sib attraction ntawm oppositely them ions thaum a Covalent Bond yog ib daim ntawv cog lus uas tshwm sim los ntawm kev sib koom ntawm electrons ntawm nuclei. Lawv nyiam ua muaj zog tshaj covalent bonds vim lub coulombic attraction ntawm ions ntawm kev them nqi rov qab.

Ntxiv mus, yog covalent daim ntawv cog lus muaj zog lossis ionic?

Covalent yog muaj zog dua vim hais tias 2 atoms koom nrog 2 los yog ntau dua txheej txheej electrons. Covalent bonds tuav tag nrho koj cov biomolecules ua ke. Ionic daim ntawv cog lus yog tsim thaum lub valence txheej plhaub electron hloov los ntawm ib tug atom mus rau lwm tus - ib tug ntau weaker kev sib cuam tshuam. Ntsev yog ib ionic bonded compound.

Ib sab saum toj no, nws qhov txawv ntawm qhov ionic thiab covalent daim ntawv cog lus yog dab tsi? Rau stabilization, lawv qhia lawv cov electrons los ntawm sab nrauv molecular orbit nrog lwm tus. Ib ionic daim ntawv cog lus yog tsim nruab nrab hlau thiab tsis yog hlau. Covalent bonding yog ib hom tshuaj kev sib raug zoo ntawm ob lub atoms uas tsis yog xim hlau uas yog tus cwj pwm los ntawm kev sib koom ua ke ntawm khub ntawm electrons nruab nrab atoms thiab lwm yam covalent bonds.

Ua li no, cov tshuaj lom neeg twg muaj zog tshaj?

Teb: Covalent daim ntawv cog lus yog daim ntawv cog lus ruaj khov. Teb: Muaj ntau txoj hauv kev atoms kev sib raug zoo rau ib leeg.

Ib co piv txwv ntawm ionic bonds yog dab tsi?

Ionic daim ntawv cog lus piv txwv muaj xws li:

  • LiF - Lithium Fluoride.
  • LiCl - Lithium Chloride.
  • LiBr - Lithium Bromide.
  • Li-Iodide Lithium Iodide.
  • NaF - Sodium Fluoride.
  • NaCl - Sodium Chloride.
  • NaBr - Sodium Bromide.
  • NaI - Sodium Iodide.
