Lewis tau paub zoo tshaj plaws rau nws qhov kev tshawb pom ntawm covalent daim ntawv cog lus thiab nws lub tswv yim ntawm cov khub electron; nws Lewis dot qauv thiab lwm yam kev koom tes rau valence bond theory tau zoo li niaj hnub kev xav ntawm tshuaj kev sib raug zoo.
Ua li no, Lewis txoj kev xav yog dab tsi?
Lewis txoj kev xav , generalization txog acids thiab bases qhia nyob rau hauv 1923 los ntawm US chemist Gilbert N. Lewis , nyob rau hauv uas ib tug acid yog suav hais tias yog ib tug compound uas, nyob rau hauv ib tug tshuaj tiv thaiv, muaj peev xwm txuas nws tus kheej mus rau ib tug unshared khub ntawm electrons nyob rau hauv lwm yam molecule.
