Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
