Taw qhia rau covalent daim ntawv cog lus
Cov nyiaj cog lus yog ib hom kev sib koom tes tshuaj lom neeg. Ob lossis ntau dua atoms siv lawv cov hluav taws xob sab nraud ua ke kom ua tiav lub xeev ntawm hluav taws xob saturation raws li cov xwm txheej zoo tagnrho, yog li tsim cov qauv tshuaj lom neeg ruaj khov. Muaj zog ua tau tsim los ntawm ntau qhov sib txig atoms sib qhia cov tshuab hluav taws xob thiab sib qhia cov hluav taws xob hu ua covalent bond. Lub ntsiab lus yog tias tom qab atomic orbits sib tshooj, muaj qhov muaj siab tias qhov hluav taws xob nruab nrab ntawm ob lub nuclei thiab hluav taws xob sib cuam tshuam ntawm ob lub nuclei.
