Txhais ntawm valence electron .:ib ib hluav taws xob los yog ib qho ntawm ob lossis ntau dua electrons nyob rau hauv lub plhaub sab nrauv ntawm ib lub atom uas yog lub luag hauj lwm rau cov tshuaj lom neeg ntawm lub atom.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog txhais los ntawm valence electron?

Hauv chemistry thiab physics, a valence electron yog lub plhaub sab nraud hluav taws xob uas yog txuam nrog ib tug atom, thiab uas muaj peev xwm koom nyob rau hauv lub tsim ntawm ib tug tshuaj daim ntawv cog lus yog hais tias lub plhaub sab nraud tsis raug kaw; nyob rau hauv ib daim ntawv cog lus ib leeg, ob qho tib si atoms hauv daim ntawv cog lus txhawb nqa ib qho valence electron thiaj li tsim tau ib khub sib koom.

Ib yam li ntawd, vim li cas lawv thiaj hu ua valence electrons? Hluav taws xob nyob rau hauv lub plhaub kawg los yog lub plhaub sab nraud yog hu ua raws li valence electron . Lawv yog hu ua so vim lawv txiav txim siab rau valency ntawm element. Valence plhaub yog lub plhaub uas muaj valence electrons . Yog li lub plhaub kawg lossis lub plhaub sab nraud tseem yog hu ua raws li valence plhaub.

Ib yam li ntawd, nws yog nug, dab tsi yog valence electron nrog piv txwv?

Tag nrho cov naj npawb ntawm electrons tam sim no nyob rau hauv lub xeem plhaub orbit yog hu ua valence electron . Rau piv txwv : Oxygen muaj 6 electrons tam sim no nyob rau hauv lub xeem orbital plhaub li no 6 yog valence electron.

F muaj pes tsawg valence electrons?
