Covalent daim ntawv cog lus muaj zog- xav tau ntau lub zog los rhuav tshem lawv. Cov khoom nrog covalent bonds feem ntau tsim cov molecules uas tsis tshua muaj melting thiab boiling cov ntsiab lus, xws li hydrogen thiab dej.
Vim li cas covalent bonds tsis muaj zog?
Covalent compounds yog cov uas muaj zog intra-molecular bonds. Qhov no yog vim hais tias cov atoms nyob rau hauv covalent molecules yog nruj heev tuav ua ke. Txhua lub molecule yeej sib txawv heev thiab lub zog ntawm kev nyiam ntawm tus kheej molecules nyob rau hauv covalentcov khoom sib xyaw ua rau qaug zog.
Vim li cas covalent daim ntawv cog lus muaj zog?
Daim Ntawv Pov Thawj Lub Zog: Covalent Bonds. Cov molecules ruaj khov muaj nyob vim covalent bonds tuav cov atoms ua ke. Peb ntsuas lub zog ntawm covalent daim ntawv cog lus los ntawm lub zog xav tau los rhuav tshem nws, uas yog, lub zog tsim nyog los cais cov atoms sib txuas. … Qhov kev sib cog lus muaj zog dua, lub zog ntau dua yuav tsum tau tawg.
Puas covalent lossis ionic bonds muaj zog dua?
Ionic Bonds
Lawv ntxhiab yuav muaj zog dua li covalent daim ntawv cog lus vim yog coulombic attraction ntawm ions ntawm cov nqi sib txawv. Txhawm rau ua kom qhov kev nyiam tshaj plaws ntawm cov ions, ionic compounds tsim siv lead ua lattices ntawm alternating cations thiab anions.
Yog covalent daim ntawv cog lus qis tshaj plaws?
Qhov tsis muaj zog tshaj ntawm cov ntawv cog lus intramolecular lossis cov khoom siv tshuaj lom neeg yog cov nyiaj ionic. tom ntej no lub polar covalent daim ntawv cog lus thiab lub zog tshaj cov tsis muaj polar covalentdaim ntawv cog lus. Muaj txawm tias tsis muaj zog intermolecular "daim ntawv cog lus" lossis ntau qhov raug quab yuam. … Cov ionic daim ntawv cog lus feem ntau yog qhov tsis muaj zog tshaj ntawm cov tshuaj muaj tseeb uas khi atoms rau atoms.
