Ionic compounds yog nruab nrab tshuaj sib xyaw ua los ntawm kev them nqi zoo ions hu ua cations thiab negatively them ions npe anions. Rau binary ionic compounds ( ionic compounds uas tsuas muaj ob hom ntawm cov ntsiab lus), cov cov tshuaj muaj npe los ntawm kev sau ntawv npe ntawm cation thawj zaug ua raws li cov npe ntawm anion.

Tsis tas li ntawd, koj ua li cas lub npe ionic compound?

Yog koj xav tau npe ionic compound , pib los ntawm kev sau cov qauv rau qhov ntawd compound . Sau tus npe ntawm cov hlau, kuj hu ua cation. Cov cation yog qhov zoo them ion nyob rau hauv compound , thiab nws yeej ib txwm sau ua ntej. Tom ntej no, sau tus npe ntawm nonmetal, los yog anion.

Ib sab saum toj no, dab tsi yog daim ntawv tseem ceeb rau cov npe ntawm cov ionic compounds uas muaj cov hlau uas tsuas yog ib hom ion? Cov daim ntawv tseem ceeb rau cov npe ntawm Hom II ionic compounds yog kom muaj npe ntawm hlau cation ua ntej, ua raws li tus nqi ntawm lub hlau cation hauv parenthesis siv cov lej roman, thiab thaum kawg tus npe base ntawm nonmetal anion nrog -ide txuas qhov kawg ntawm nws.

Kuj kom paub, cov cai hauv kev naming ionic compounds yog dab tsi?

Thaum naming ionic compounds, peb ua raws li cov kev cai dav dav:

  • Txheeb xyuas thiab muab lub npe cation; Qhov no yog cov khoom hlau lossis polyatomic cation.
  • Txheeb xyuas thiab npe cov anion; qhov no yog ib qho nonmetal. Hloov cov lus rau '-ide,' lossis siv lub npe polyatomic anion.

Dab tsi yog ionic formula?

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.
