Txhua 100% symmetrical tetrahedral molecule yuav tsis muaj polar . Tetrahedral molecules tsis muaj cov khoom siv hluav taws xob tsis sib txuas electron khub Lone khub muaj nyob hauv lub plhaub sab nraud ntawm lub plhaub ntawm cov atoms. … Electron khub yog li ntawd suav hais tias yog ib leeg khub yog tias ob lub electrons raug ua ke tab sis tsis siv rau hauv kev sib txuas tshuaj. Yog li, tus naj npawb ntawm ib khub electrons ntxiv rau cov xov tooj ntawm cov khoom siv hluav taws xob sib npaug ntawm tag nrho cov valence electrons nyob ib ncig ntawm ib lub atom. https://en.wikipedia.org › wiki › Lone_pair
