Rau binary ionic tshuaj sib xyaw (ionic tshuaj sib xyaw uas tsuas muaj ob hom ntsiab), lub tshuaj sib xyaw muaj npe los ntawm kev sau ntawv npe ntawm cation thawj zaug ua raws li cov npe ntawm anion.

Piv txwv li, dab tsi yog cov piv txwv ntawm covalent bonds?

Piv txwv ntawm Covalent Bond:

  • Dej. Ib qho piv txwv yog dej. Dej muaj covalent daim ntawv cog lus uas muaj hydrogen thiab oxygen bonding ua ke los ua H2O.
  • Pob zeb diamond. Lub pob zeb diamond yog ib qho piv txwv ntawm Giant Covalent daim ntawv cog lus ntawm carbon. Lub pob zeb diamond muaj cov qauv loj heev.
  • Vulcanized roj hmab. Lwm qhov piv txwv yog vulcanized roj hmab.

Kuj Paub, yog co2 yog ionic compound? Teb thiab piav qhia: CO2 yog molecular compound . Ionic compounds yog tsim los ntawm cov hlau tsis muaj hlau thiab cov khoom hlau.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog tus qauv ionic?

Zuag qhia tag nrho ionic formula rau ib lub compound yuav tsum yog hluav taws xob nruab nrab, txhais tau tias nws tsis muaj nqi. Thaum sau ntawv qauv rau cov ionic compound, cation los ua ntej, ua raws li cov anion, ob qho tib si nrog cov lej subscripts los qhia tus naj npawb ntawm atoms ntawm txhua tus.

Ib co piv txwv ntawm ionic compounds 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.
