Thaum siv lub zog, cov txheej ntawm cov hlau ions tuaj yeem xaub hla ib leeg thaum tseem raug nyiam mus rau ' hiav txwv' ntawm delocalised electrons. Cov tshuaj ionic thiab covalent loj heev feem ntau yog nkig. Lawv tawg thaum khoov lossis ntaus vim ntau daim ntawv cog lus muaj zog ionic lossis covalent daim ntawv cog lus tawg ib zaug
Vim li cas cov qauv ionic nkig?
Ionic cov khib nyiab muaj cov ntsiab lus melting siab dua li cov hlau tab sis muaj cov ntsiab lus melting tsawg dua covalent. … -Cov ionic solids yog tawv thiab nkig vim cov ions hauv ionic cov khoom muaj nyob rau hauv ib lub lattice vim yog cov electrostatic quab yuam ntawm attraction nyob rau hauv cations thiab anions nrog rau cov repulsion nrog cov zoo li nqi
Vim li cas ionic lattices feem ntau nkig?
Ionic tebchaw yuav muaj cov ntsiab lus melting siab thiab kub, vim tias qhov kev nyiam ntawm ions hauv cov lattice muaj zog heev. Tsiv ions tawm ntawm lub lattice cuam tshuam cov qauv, yog li cov ionic tebchaw zoo li nkig es tsis tuaj yeem.
Puas yog ionic solids nkig?
Ionic cov khib nyiab yog tsim los ntawm cations thiab anions tuav ua ke los ntawm electrostatic rog. Vim yog lub zog ntawm cov kev sib cuam tshuam, cov khoom ionic nyiam mus nyuaj, nkigthiab muaj cov ntsiab lus melting siab.
Vim li cas ionic crystals tawg thaum ntaus nrog rauj?
Lub zog quab yuam ntawm cov ions zoo li themua rau cov siv lead ua tawg. … (B) Thaum ntaus los ntawm ib rab rauj, cov tshuaj chloride ions tsis zoo raug yuam nyob ze ib leeg thiab lub zog quab yuam ua rau cov siv lead ua tawg.
