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. Ionic compound formulas yog sau siv tus nqi qis tshaj ntawm ions.
Ua li no, koj sau lub npe ntawm binary ionic compound li cas?
Rau ib binary ionic compound , hlau yuav ib txwm yog thawj lub hauv paus hauv cov qauv, thaum lub nonmetal yuav ib txwm yog qhov thib ob. Cov hlau cation yog lub npe ua ntej, ua raws li cov nonmetal anion. Subscripts hauv cov qauv tsis cuam tshuam rau npe.
NaCl yog binary compound? Hauv chemistry, a binary compound yog ib yam dab tsi uas muaj ob lub ntsiab. Hauv ib binary compound , tej zaum tsuas muaj ib qho ntawm txhua lub ntsiab lus. Peb pom qhov no nrog sodium chloride (nqaij) NaCl , uas muaj ib qho sodium (Na) thiab ib qho tshuaj chlorine (Cl).
Yog li ntawd, qhov piv txwv ntawm binary ionic compound yog dab tsi?
A binary ionic compound yog tsim los ntawm ions ntawm ob yam sib txawv - ib qho yog hlau, thiab lwm yam yog nonmetal. Rau piv txwv hlau (III) iodide, FeI3, yog tsim los ntawm hlau ions , Fe3+ (cov ntsiab lus hlau yog hlau), thiab iodide ions , kuv- (cov ntsiab lus iodine yog nonmetal).
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.

Yuav ua li cas yog cov structural units uas ua ionic compounds thiab yuav ua li cas lawv hu ua?
Rau binary ionic compounds (ionic compounds uas muaj tsuas yog 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 anion. Piv txwv li, KCl, ib qho ionic compound uas muaj K + thiab Cl-ions, yog lub npe hu ua potassium chloride
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 npe ionic compounds piv txwv li cas?
Rau binary ionic compounds (ionic compounds uas muaj tsuas yog 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 anion. Piv txwv li, KCl, ib qho ionic compound uas muaj K + thiab Cl-ions, yog lub npe hu ua potassium chloride
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Puas yog tag nrho cov ionic compounds muaj cov qauv lattice?
Ib qho ionic compound yog cov qauv loj heev ntawm cov ions. Cov ions muaj qhov tsis tu ncua, rov ua dua tshiab hu ua ionic lattice. Qhov no yog vim li cas cov khoom ioniccompounds tsim cov muaju nrog cov duab tsis tu ncua
