Raws li Coulomb Txoj Cai, raws li tus atomic tus naj npawb nce nyob rau hauv ib tug series ntawm atoms , cov nuclear kev nyiam rau electrons kuj yuav nce, yog li rub lub electron (s) los ze zog rau lub nucleus. Xws li kev sib raug zoo ntawm atomic tus lej thiab atomic radius yog direct correlation.

Ib yam li ntawd, kev sib raug zoo ntawm tus lej atomic thiab atomic radius yog dab tsi?

Cov tus lej atomic yog tus nqi ntawm cov protons muaj nyob rau hauv atom . Vim li ntawd, peb tuaj yeem hais tias lub tus lej atomic sawv cev rau tus nqi zoo ntawm cov atom . Raws li tus nqi zoo ntawm cov atom nce lub atomic radius txo qis vim hais tias tus nqi zoo yuav coj electrons los ze zog rau lub nucleus.

Ib tug kuj yuav nug, dab tsi yog lub zog coulombic thiab nws cuam tshuam los ntawm nuclear nqi li cas? Qhov zoo nuclear nqi ntawm ib qho atom yog qhov zoo nqi 'xav' los ntawm VALENCE electron. Qhov no txhais tau hais tias noj mus rau hauv tus account qhov txaus nyiam zog hnov ntawm cov protons thiab electrons raws li zoo raws li lub replusive zog hnov ntawm lub valence electrons thiab cov tub ntxhais (sab hauv) electrons.

Ua raws li qhov no hauv kev xav, coulombic attraction nyob ntawm dab tsi?

Qhov no coulombic attraction ua rau cov electrons mus ncig ncig lub nucleus.) Lub zog ntawm lub coulombic attraction nyob ntawm ob yam: qhov loj ntawm lub atom. Tag nrho cov nqi ntawm lub atom.

Dab tsi yog qhov kev sib raug zoo ntawm coulombic attraction thiab ionization zog?

Qhov loj dua ionization zog , qhov nyuaj dua rau tshem tawm ib qho hluav taws xob. Siv tib yam Coulombic attraction tswv yim, peb tuaj yeem piav qhia thawj zaug ionization zog trends nyob rau hauv lub periodic rooj. Txoj kev nyiam ntawm ib tug atom nyob rau hauv ib tug molecule rau nyiam sib koom electrons rau nws tus kheej yog hu ua electronegativity.
