Ntau yam tseem ceeb, lossis subatomic, cov khoom ntawm cov khoom muaj cov khoom siv hluav taws xob. Piv txwv li, electrons muaj tus nqi tsis zoothiab protons muaj tus nqi zoo, tab sis neutrons muaj pes tsawg tus nqi.
Yuav ua li cas them electrons e nqa?
Electron, lub teeb ruaj khov subatomic particle paub. Nws nqa tus nqi tsis zoo ntawm 1.602176634 × 10 - 19 coulomb, uas suav tias yog chav tsev tseem ceeb ntawm hluav taws xob.
Puas electrons tsis zoo lossis raug them zoo?
Inside ib atom yog protons, electrons thiab neutrons. Cov protons raug them zoo, cov electrons raug them tsis zoo, thiab cov neutrons yog nruab nrab. Yog li ntawd, txhua yam yog tsim los ntawm tus nqi. Cov nqi sib tw sib nyiam (tsis zoo rau qhov zoo).
Puas electron nqa hluav taws xob?
Nyob hauv ntau cov ntaub ntawv, cov electrons nruj nreem khi rau cov atoms. … Cov hluav taws xob xoob ua kom yooj yim rau hluav taws xob ntws los ntawm cov ntaub ntawv no, yog li lawv hu ua hluav taws xob conductors. Lawv ua hluav taws xob. Cov electrons txav tau xa hluav taws xob los ntawm ib qho mus rau lwm qhov.
Electrons nce zog li cas?
Lub tshuab hluav taws xob tuaj yeem nce lub zog uas nws xav tau by absorbing light. Yog hais tias lub electron dhia los ntawm lub zog thib ob mus rau thawj theem zog, nws yuav tsum muab qee lub zog los ntawm kev tawm lub teeb. Lub atomabsorbs los yog emits lub teeb nyob rau hauv discrete pob ntawv hu ua photons, thiab txhua photon muaj ib tug meej lub zog.
