Txhua yam ionic compounds yog khoom ntawm chav kub , txawm li cas los muaj a chav kawm ntawm chav tsev kub ionic kua . [1] Cov no yog a tshwm sim los ntawm kev tsis sib haum xeeb ntawm cov ions nyob rau hauv daim ntawv khov.
Ua li no, yog vim li cas ionic bonds khov nyob rau hauv chav tsev kub?
Ionic cov tebchaw muaj siab melting thiab boiling cov ntsiab lus, yog li lawv nyob rau hauv lub khov kho xeev ntawm chav kub . Lub zog no overcomes lub zog electrostatic zog ntawm attraction uas ua nyob rau hauv tag nrho cov lus qhia ntawm tus oppositely them ions : Qee lub zog tau kov yeej thaum yaj.
Tsis tas li ntawd, vim li cas cov kua ionic ua kua hauv chav sov? Li no, cov chaw zov me nyuam ntawm cov ions yog sib cais ntau tshaj nyob rau hauv ib txwm ionic tshuaj sib xyaw. Li no lub zog xav tau los rhuav lub ionic daim ntawv cog lus qis dua, nyob ib puag ncig 25 meV lossis tsawg dua, uas txhais tau tias lawv yog kua ntawm chav tsev kub.
Hais txog qhov no, dab tsi yog ionic compounds ntawm chav tsev kub?
Covalent Bonds vs Ionic Bonds
| Covalent Bonds | Ionic Bonds | |
|---|---|---|
| Lub xeev ntawm chav tsev kub: | Kua los yog gaseous | Khoom |
| Polarity: | Tsawg | Siab |
Puas yog ionic bonds yog kua lossis roj?
Nyob rau hauv chav tsev kub thiab ib txwm atmospheric siab, covalent tebchaw tej zaum yuav muaj raws li ib tug khov kho , a ua kua ,lub a gas , hos ionic cov tebchaw tsuas muaj raws li cov khib nyiab.

Qhov kub ntawm qhov hluav taws kub kub li cas?
Feem ntau hom ntoo yuav pib combusting ntawm li 300 degrees Celsius. Cov pa roj hlawv thiab nce qhov kub ntawm cov ntoo mus txog 600 degrees Celsius (1,112 degrees Fahrenheit). Thaum cov ntoo tso tawm tag nrho nws cov gases, nws tawm charcoal thiab tshauv
Vim li cas ionic bonds khov ntawm chav tsev kub?
Ionic tebchaw muaj cov ntsiab lus siab melting thiab boiling, yog li lawv nyob rau hauv cov khoom nyob rau hauv chav tsev kub. Lub zog no overcomes lub zog electrostatic zog ntawm attraction uas ua nyob rau hauv tag nrho cov lus qhia ntawm tus oppositely them ions: ib co quab yuam tau kov yeej thaum lub melting
Lub xeev ntawm ionic compounds nyob rau hauv chav tsev kub yog dab tsi?
Covalent Bonds vs Ionic Bonds Covalent Bonds Ionic Bonds State nyob rau hauv chav tsev kub: kua los yog gaseous khoom polarity: Tsawg siab
Cov kua methanol lossis ethanol twg muaj qhov vapor siab dua ntawm chav tsev kub?
Methanol muaj qhov loj dua vapor siab nyob rau hauv chav tsev kub vim hais tias nws muaj qis molecular hnyav thaum piv nrog ethanol, uas txhais tau hais tias nws muaj zog intermolecular zog
Vim li cas bromine yog kua hauv chav tsev kub?
Bromine yog kua nyob rau hauv chav tsev kub vim hais tias bromine molecules muaj txaus intermolecular kev sib cuam tshuam nyob rau hauv cov kev mob mus rau hauv lub
