Amorphous khoom, ib yam noncrystalline solid nyob rau hauv uas atoms thiab molecules tsis koom nyob rau hauv ib tug meej lattice qauv. Cov khoom siv xws li iav, yas, thiab gel. Khoom thiab kua yog ob hom condensed teeb meem; ob leeg yog tsim los ntawm atoms nyob ze rau ib leeg.
Puas yog cov khoom amorphous nkig?
Amorphous steel yog cov khoom siv tawv heev uas ua rau nws nyuaj rau xuas nrig ntaus rau hauv lub tshuab lamination.
Puas amorphous solids irregularly?
Amorphous solids tawg rau hauv cov khoom tsis sib xws nrog cov npoo tsis sib xws. Thiab lawv tsis muaj qhov txawv txav lossis cov duab ntawm cov molecules. yog li lawv tsis tuaj yeem txheeb xyuas los ntawm lawv cov qauv ua cov muaju.
Yuav ua li cas cov khib nyiab nkig?
Ionic cov khib nyiab yog tsim los ntawm cov lattice uas muaj qhov sib txawv ntawm cov ions. Ib qho ntawm cov khoom siv ionic tshaj plaws yog sodium chloride.
- Cov ntsiab lus melting siab thiab cov ntsiab lus kub kub vim muaj zog ionic bonds. …
- Lawv nkim - yuav tawg nrog rauj.
- nquag soluble hauv dej.
Puas yog crystalline solids nkig?
Cov piv txwv ntawm cov khoom no yog iav thiab yas. Muaj plaub hom crystalline solids: Ionic solids-Ua los ntawm qhov zoo thiab tsis zoo ions thiab tuav ua ke los ntawm electrostatic attractions. Lawv yog cov cim los ntawm cov ntsiab lus melting siab heev thiab brittleness thiab yogcov neeg pluag conductors nyob rau hauv lub solid state.
