Ionic compounds feem ntau daim ntawv nruab nrab cov ntsiab lus uas yog hlau thiab cov ntsiab lus uas yog nonmetals. Piv txwv li, hlau calcium (Ca) thiab nonmetal chlorine (Cl) daim ntawv tus ionic compound calcium chloride (CaCl2). Hauv no compound , muaj ob yam tsis zoo chloride ions rau txhua qhov zoo calcium ion.

Ib yam li ntawd, tib neeg nug, dab tsi yog cov ntsiab lus ionic?

Ionic compounds yog cov khoom sib xyaw ua ke ions . Ob- keeb cov tshuaj feem ntau yog ionic thaum ib keeb yog hlau thiab lwm yam yog tsis-hlau. Piv txwv li: sodium chloride: NaCl, nrog Na+ thiab Cl- ions . calcium phosphide: Ca3P2, nrog Ca2+ thiab P3- ions.

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.

Tsuas yog li ntawd, dab tsi ua rau ib qho ionic compound?

Ionic compounds yog tshuaj sib xyaw ua los ntawm ions . Cov no ions yog atoms uas nce lossis poob electrons, muab lawv tus nqi zoo lossis tsis zoo. Cov hlau zoo li plam electrons, yog li lawv dhau los ua cations thiab muaj cov txiaj ntsig zoo. Nonmetals zoo li tau txais electrons, tsim cov anions uas muaj tus nqi tsis zoo.

Yuav ua li cas koj txheeb xyuas daim ntawv cog lus ionic?

Muaj ob peb txoj kev sib txawv txiav txim yog tias a daim ntawv cog lus yog ionic los yog covalent. Los ntawm txhais, ib ionic daim ntawv cog lus yog nruab nrab ntawm ib tug hlau thiab ib tug nonmetal, thiab ib tug covalent daim ntawv cog lus yog nruab nrab ntawm 2 nonmetals. Yog li koj feem ntau tsuas yog saib ntawm lub rooj zaum thiab txiav txim seb koj cov khoom puas yog ua los ntawm cov hlau / nonmetal lossis tsuas yog 2 nonmetals.
