Ntawm qhov tod tes, cov atoms (ions) hauv cov ntaub ntawv ionic qhia muaj zog rau lwm cov ions hauv lawv thaj tsam. Qhov no feem ntau ua rau cov ntsiab lus melting qis rau covalent solids, thiab cov ntsiab lus melting siab rau ionic solids.
Puas ionic compounds muaj qis lossis siab melting point?
Raws li cov ionic lattice muaj ntau cov ions, yuav tsum muaj ntau lub zog los kov yeej qhov kev sib txuas ntawm ionic thiaj li ionic compounds muaj cov ntsiab lus kub thiab kub.
Vim li cas cov ionic tebchaw muaj qis melting point?
Lub melting thiab boiling cov ntsiab lus ntawm molecular tebchaw yog feem ntau tsawg heev piv rau cov ionic compounds. Qhov no yog vim lub zog xav tau los cuam tshuam cov kev sib cuam tshuam ntawm cov molecules tsawg dua li lub zog xav tau los rhuav tshem cov ionic bonds hauv crystalline ionic compound (Daim duab 6.2. 1).
Puas yog qhov qis melting ionic lossis covalent?
Covalent compounds feem ntau muaj cov ntsiab lus kub kub thiab melting tsawg, thiab muaj nyob rau hauv tag nrho peb lub cev lub cev ntawm chav tsev kub. Covalent compounds tsis ua hluav taws xob; Qhov no yog vim covalent tebchaw tsis muaj cov khoom uas muaj peev xwm thauj electrons.
Yuav ua li cas cov compound muaj qis melting point?
Cov tshuaj uas muaj cov ntsiab lus melting qis tshaj plaws yog Heliumthiab cov khoom uas muaj cov ntsiab lus melting siab tshaj plaws yog Carbon. Kev sib koom ua ke siv rau kev sib tsoopoint yog Celsius (C).
