Electrovalent compounds yog tsim los ntawm kev nce lossis poob ntawm electrons ntawm cov khoom. Li no lawv muaj zog intermolecular rog. Li no lawv feem ntau yog khov.
Vim li cas ionic compounds solids nyob rau hauv chav tsev kub tab sis covalent compounds zoo li kua los yog gases ntawm chav tsev kub?
Ionic compounds feem ntau yog cov khib nyiab ntawm chav tsev kub. … Vim yog lub zog muaj zog ntawm cov atoms, ionic compounds zoo li muaj cov ntsiab lus melting siab heev. Daim duab B. Cov hom tshuaj no yuav zoo li yaj hauv dej (saib daim duab B).
Vim li cas ionic compounds feem ntau yog khov thiab nkig ntawm chav tsev kub?
- Ionic tebchaw zoo li cov khoom tawg yooj yim ntawm chav tsev kub, yog li lawv feem ntau tawg sib nrug thaum ntaus Cov cuab yeej no yog vim qhov kev npaj ntawm ions hauv qhov rov ua peb-dimension a qauv hu ua Crystal lattice. - Muaj zog ionic bonds txhais tau hais tias ionic compounds muaj cov ntsiab lus melting siab.
Puas yog tag nrho cov ionic compounds solids ntawm chav tsev kub?
Puas yog tag nrho cov ionic compounds khov ntawm chav sov? Ionic tebchaw feem ntau yog cov khib nyiab ntawm chav tsev kub. Lawv tsim cov qauv siv lead ua lattice thaum muaj ntau tshaj ib lub molecule (saib daim duab A). Daim ntawv ceeb toom tias cov nqi zoo thiab cov nqi tsis zoo hloov pauv.
Vim li cas ionic compounds khov?
Nyob hauv ib qho chaw ionic, muaj ntau lab ions tam sim no thiab tag nrho cov ions no tau tuav ua ke los ntawm electrostatic rog. Cov rog no muaj zog heev, tuav ions ruaj khov rau hauv qhov chaw thiab yog li tsim cov qauv siv lead ua lattice. … Li no, ionic cov khoom muaj nyob tsuas yog cov khoom nyob hauv ib txwm muaj
