Rooj ntsev yog ib qho piv txwv ionic compound . Sodium thiab chlorine ions tuaj ua ke rau formsodium chloride, los yog NaCl. Sodium atom ntawm no compound poob ib qho hluav taws xob los ua Na +, thaum lub chlorine atom nce anelectron los ua Cl-. Qhov no yog vim cov nqi yuav tsum bebalanced rau lub ionic compound.

Ntawm no, cov lus ntsev puas yog ionic lossis covalent compound?

Atoms uas sib koom electrons nyob rau hauv ib tug chemical bond muaj covalent bonds . Cov pa oxygen molecule (O2) yog ib qho piv txwv zoo ntawm cov molecule nrog a covalent daim ntawv cog lus. Ionicbonds tshwm sim thaum electrons pub dawb los ntawm ib lub atom mus rau lwm tus. Rooj ntsev (NaCl) yog ib qho piv txwv ntawm a compound nrog ib ionic daim ntawv cog lus.

Qhov thib ob, hom tshuaj twg yog cov ntsev ntsev? Lub zog electrostatic attraction ntawm adjacentcations thiab anions yog hu ua ionic bond. Qhov feem ntau piv txwv ntawm ionic compound yog sodium chloride NaCl, zoo dua lub npe hu ua rooj ntsev . Tsis zoo li covalent tshuaj sib xyaw , tsis muaj xws li ib tug molecule ntawm ib tug ionic compound.

Ntawm no, vim li cas lub rooj ntsev yog qhov sib xyaw?

Rooj ntsev (NaCl) yog tshuaj lom neeg compound tsim los ntawm Sodium thiab chlorine. Ntsev yog suav tias yog achemical compound vim nws yog ib tug ruaj khov qauv tsim ntawm ob yam tshuaj. Tsis muaj tshuaj tiv thaiv, lub ntsev yuav nyob twj ywm raws li nws yog, tsis muaj kev tawg lossis txuas lwm cov atoms lossis molecules rau nws tus kheej.

Puas yog tag nrho cov ionic compounds ntsev?

Hauv qab no txhais, tag nrho cov ionic compounds yog ntsev , thiab tag nrho cov ntsev yog ionic compounds Yog li ntawd, ib yam dab tsi zoo li sodium hydroxide (Na + OH-, twv yuav raug hu ib ionic compound ) tuaj yeem raug hu ua a ntsev.
