Nqe Lus Nug 3: Dab tsi ntawm qhov tsim ntawm cov khoom siv electrovalent nyob ntawm? Teb: Qhov tsim ntawm ib qho ionic compound nyob ntawm cov hauv qab no: (i) Tsawg ionisation zog: Tsawg dua yog lub zog ionisation ntawm ib lub atom, ntau dua yuav yog nws nyiam tsim cation los ntawm kev poob. lub valence electron.
Dab tsi yog yam ntawm cov ionic bond tsim nyob ntawm?
- Ob lub atom yuav tsum sib txawv.
- Ionization peev xwm ntawm ib lub atom yuav tsum me me.
- Electron affinity ntawm ib lub atom yuav tsum siab.
- Electronegativity ntawm ib lub atom yuav tsum siab.
- Qhov txawv ntawm electronegativity ntawm ob yuav ntau dua lossis sib npaug rau 1.7.
Dab tsi yog yam cuam tshuam rau Electrovalent daim ntawv cog lus?
Nyob rau hauv tsab xov xwm no, peb yuav tsum kawm cov yam uas cuam tshuam rau kev tsim cov ionic daim ntawv cog lus thiab lub tswv yim ntawm kev sib txawv electrovalency
- Ionization zog ntawm Electropositive Atom:
- Electron Affinity lossis Electron Gain Enthalpy ntawm Electronegative Atom:
- Lattice zog lossis Lattice Enthalpy:
- Qhov txawv ntawm Electronegattivities:
Dab tsi yog yam cuam tshuam rau kev tsim cov cation?
Ionization zog, electronegativity, thiab lattice zog yog yam uas cuam tshuam rau kev tsim cov ionic bonds ntawm cov khoom.
Dab tsi yog tshajCov yam tseem ceeb hauv kev tsim cov ionic compounds?
Ionization zog yog lub zog uas yuav tsum tau tshem tawm cov hluav taws xob. Electronegativity yog ib yam khoom muaj peev xwm nyiam cov electrons los ua kev sib raug zoo. Lattice zog yog lub zog uas yuav tsum tau sib cais los yog muab tso ua ke ions los tsim ib daim ntawv cog lus ionic.

Puas yog cov dab dab dab dab dab dab dab dab dab dab dab dab?
Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers. Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Cov piv txwv ntawm cov kuab tshuaj thiab cov kuab tshuaj yog dab tsi?
Solutes yog cov khoom uas yaj rau hauv cov kuab tshuaj thiab peb xaus nrog kev daws. Qee qhov piv txwv ntawm cov kuab tshuaj yog dej, ethanol, toluene, chloroform, acetone, mis nyuj, thiab lwm yam. Piv txwv ntawm cov kuab tshuaj muaj xws li, qab zib, ntsev, oxygen, thiab lwm yam … Cov dej dej muaj dej (kua kua) thiab yaj oxygen (solute).
Dab tsi yog kev xav ntawm autonomists dab tsi yog qhov kev xav ntawm kev zoo nkauj ntawm kev coj ncaj ncees?
Kev lig kev cai, muaj ob txoj haujlwm tawm tsam kev xav txog kev coj ua raws li kev cai lij choj ntawm kev ntsuas kev ncaj ncees ntawm kev kos duab: 'kev coj ncaj ncees kev ncaj ncees Ethics lossis kev coj ncaj ncees yog ib ceg ntawm kev xav uas "
Nyob hauv kev tsim cov nyiaj electrovalent?
Ionic daim ntawv cog lus, tseem hu ua electrovalent daim ntawv cog lus, hom kev sib txuas tsim los ntawm electrostatic attraction ntawm oppositely them ions nyob rau hauv ib tug tshuaj compound. … Lub atom uas poob cov electrons los ua ib tug zoo charged ion (cation), thaum ib tug uas nce lawv ua ib tug negatively charged ion (anion).
Dab tsi hauv qab no yog tus yam ntxwv ntawm tus neeg ua txhaum ntawm kev tsim txom cov laus?
Cov yam ntxwv muaj xws li: tus neeg raug tsim txom nyob ntawm tus neeg ua txhaum rau kev saib xyuas txhua hnub, tus neeg txhaum muab kev pab cuam txhua hnub, tus neeg ua txhaum muaj tsawg dua 3 tus phooj ywg, tus neeg ua txhaum poob hauj lwm, tus neeg txhaum muaj teeb meem yav dhau los nrog tus tub ceev xwm, tus neeg ua txhaum tau nrhiav kev sab laj, tus neeg ua txhaum muaj cov khoom siv… Leej twg yog tus ua txhaum loj ntawm kev tsim txom cov laus?
