Rau binary ionic compounds ( ionic compounds 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. Rau piv txwv , KCl, ib ionic compound uas muaj K+ thiab Cl- ions , yog lub npe hu ua potassium chloride.
Hais txog qhov no, 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.
Qhov thib ob, cov cai hauv kev naming compounds yog dab tsi? Thaum twg npe molecular tshuaj sib xyaw prefixes yog siv los dictate tus naj npawb ntawm ib tug muab lub ntsiab tam sim no nyob rau hauv lub compound . "mono-" qhia ib, "di-" qhia ob, "tri-" yog peb, "tetra-" yog plaub, "penta-" yog tsib, thiab "hexa-" yog rau, "hepta-" yog xya, "octo-" yog yim, "nona-" yog cuaj, thiab "deca" yog kaum.
Tom qab ntawd, dab tsi yog cov cai hauv kev naming ionic compounds?
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 bond thiab piv txwv?
Lub ntsiab txhais ntawm ionic daim ntawv cog lus yog thaum tus nqi zoo ion forms ib daim ntawv cog lus nrog tus nqi tsis zoo ions thiab ib lub atom hloov electrons mus rau lwm tus. Ib piv txwv ntawm ib ionic daim ntawv cog lus yog tshuaj compound Sodium Chloride.

Yam ua piv txwv piv txwv li cas?
Ib khub xaj yog ib khub ntawm tus lej hauv ib qho kev txiav txim. Piv txwv li, (1, 2) thiab (- 4, 12) raug txiav ua khub. Qhov kev txiav txim ntawm ob tus lej tseem ceeb: (1, 2) tsis sib npaug rau (2, 1) -- (1, 2) ≠ (2, 1)
Yuav ua li cas koj lub npe compounds nyob rau hauv Khan Academy?
Rau binary ionic compounds (ionic compounds uas tsuas muaj ob hom ntawm cov ntsiab lus), cov tebchaw muaj npe los ntawm kev sau lub npe ntawm cov cation ua ntej tom qab lub npe ntawm cov anion
Organic compounds thiab inorganic compounds yog dab tsi?
Lub ntsiab sib txawv yog nyob rau hauv lub xub ntiag ntawm ib tug carbon atom; cov organic tebchaw yuav muaj cov pa roj carbon atom (thiab feem ntau yog hydrogen atom, tsim hydrocarbons), thaum yuav luag tag nrho cov inorganic tebchaw tsis muaj ib qho ntawm ob lub atoms. Meanwhile, inorganic tebchaw muaj xws li cov ntsev, hlau, thiab lwm yam elemental compounds
Koj npe binary covalent compounds li cas?
Naming Binary Covalent Compounds Lub npe tsis yog hlau nyob sab laug rau sab laug ntawm lub sij hawm los ntawm nws lub npe elemental. Lub npe rau lwm yam uas tsis yog-hlau los ntawm nws lub npe elemental thiab qhov xaus-ide. Siv cov prefixes mono-, di-, tri-. los qhia tus naj npawb ntawm cov khoom ntawd hauv cov molecule. Yog tias mono yog thawj lub npe, nws nkag siab thiab tsis sau
Koj sau cov qauv li cas rau binary ionic compounds?
Formulas rau binary compounds pib nrog cov hlau ua raws li cov nonmetal. Cov nqi zoo thiab tsis zoo yuav tsum thim tawm ib leeg. Cov qauv ionic compound yog sau siv qhov qis tshaj ntawm ions
