Covalent bonding tshwm sim thaum khub ntawm electrons khub ntawm electrons Tus khub electron raug sib koom los ntawm cov atoms hu ua kev sib txuas khub; lwm peb khub ntawm electrons ntawm txhua chlorine atom hu ua ib khub. Cov khub ib leeg tsis koom nrog kev sib koom ua ke. Yog hais tias ob qho tib si electrons nyob rau hauv ib tug covalent daim ntawv cog lus los ntawm tib lub atom, daim ntawv cog lus yog hu ua ib tug sib koom tes covalent daim ntawv cog lus. https://chem.libretexts.org › 1.03_Lewis_Structures

are shared by atoms. Atoms yuav sib cog lus nrog lwm cov atoms kom tau txais kev ruaj ntseg ntxiv, uas tau txais los ntawm kev tsim lub plhaub hluav taws xob tag nrho. Los ntawm kev sib koom lawv sab nrauv feem ntau (valence) electrons, atoms tuaj yeem sau lawv lub plhaub hluav taws xob sab nraud thiab nce kev ruaj ntseg.
Electrons hauv daim ntawv cog lus yog dab tsi?
Ib daim ntawv cogalent thaum qhov sib txawv ntawm cov electronegativities ntawm ob lub atomsme me dhau rau kev hloov hluav taws xob los ua ions. Sib koom electrons nyob rau hauv qhov chaw nruab nrab ntawm ob lub nuclei hu ua bonding electrons. Cov khub sib raug zoo yog "cov kua nplaum" uas tuav cov atoms ua ke hauv cov khoom siv molecular.
Electron txav hauv covalent bonds li cas?
Covalent bonding tshwm sim ntawm cov atoms ntawm cov hlau tsis yog hlau. … Los ntawm kev sib tshooj orbitals, lub plhaub sab nraud ntawm tag nrho cov atoms sib txuas tau puv. Cov electrons sib koom txav nyob rau hauv lub orbitals nyob ib ncig ntawm ob lub atomsThaum lawv txav mus, muaj kev nyiam ntawm cov hluav taws xob tsis zoo no thiab cov nuclei uas muaj txiaj ntsig zoo.
Puas covalent daim ntawv cog lus nce electrons?
Covalent bonding tsis tsim electrons, nws yooj yim ua ke lawv kom txhua lub atom tau nkag mus rau tsawg kawg ib qho hluav taws xob ntau dua li ua ntej daim ntawv cog lus. Covalent bonding tshwm sim ntawm cov atoms uas zoo sib xws electronegativity, thiab yog li feem ntau tshwm sim ntawm non-metals.
Yuav ua li cas thaum lub sij hawm covalent bonding?
Covalent daim ntawv cog lus, uas tuav cov atoms nyob rau hauv ib tug neeg molecule ua ke, yog tsim los ntawm kev sib koom ntawm electrons nyob rau hauv lub sab nrauv atomic orbitalsKev faib tawm thiab cov hluav taws xob tsis sib koom hauv sab nrauv orbitals yog ib qho kev txiav txim loj ntawm peb-dimensional zoo thiab tshuaj reactivity ntawm molecules.
