Ionic crystals yog crystalline structurestuas loj hlob los ntawm ionic bonds thiab tuav ua ke byelectrostatic attraction. Ionic bonds yog atomic bondscreated los ntawm qhov attraction ntawm ob qhov sib txawv them ions . Qhov kev sib cog lus feem ntau yog nruab nrab ntawm cov hlau thiab tsis yog hlau.

Nyob rau hauv no hais txog, ua li cas ionic compounds tsim muaju?

Crystals . Ntau compounds daim ntawv molecules, tab sis ionic compounds tsim cov muaju xwb. Ib tug crystalconsists ntawm ntau alternating zoo thiab tsis zoo ions ua ke ua ke nyob rau hauv ib tug matrix. Sodium thiab chloride ions yog attracted rau ib leeg vim lawv oppositely them, sothey tsim ionic daim ntawv cog lus.

Ib yam li ntawd, koj txhais li cas los ntawm ionic siv lead ua? Cov txhais ntawm ib ionic siv lead ua yog a siv lead ua cov qauv uas loj hlob los ntawm cov tshuaj bonds ntawm ob oppositely them atoms uas yog tuav ua ke byelectrostatic attraction. Ib qho piv txwv ntawm ib ionic siv lead ua istable ntsev.

Tsis tas li lo lus nug yog, dab tsi yog ionic crystal muab piv txwv?

Ib ionic siv lead ua muaj ions ua ke los ntawm electrostatic attraction. Kev npaj ntawm ions nyob rau hauv ib txwm, geometric qauv hu ua a siv lead ua daim kab xev. Piv txwv ntawm tej siv lead ua yog cov alkali halides, uas suav nrog: potassium fluoride (KF) potassium chloride (KCl)

Vim li cas ionic crystals nyuaj?

Ionic crystals yog nyuaj vim nruj lattices, hais, qhov zoo thiab tsis zoo ions txuas nrog lawv tus kheej. Ionic cov tebchaw yog brittle vim muaj cov tsis directional bond ntawm lub ions.
