Ib ion yog ib atom uas muaj tau txais lossis poob ib lossis ntau dua electrons thiab yog li ntawd muaj qhov tsis zoo lossis qhov zoo nqi . Ib qho cation yog ib qho atom uas tau poob ib tug valence hluav taws xob thiab yog li ntawd muaj ntau qhov zoo protons dua li qhov tsis zoo electrons , yog li nws yog qhov zoo raug nqi.

Kuj paub, dab tsi yog tus nqi ntawm lub atom yog tias nws tau txais ib qho hluav taws xob?

Txawm li cas los xij, yog ib yam dab tsi tshwm sim los ua ib qho atom poob los yog nce ib tug electron ces cov atom yuav tsis nyob nruab nrab lawm. Ib atom uas nce los yog poob ib tug electron ua ion. Yog nws nce ib tug tsis zoo hluav taws xob , nws dhau los ua ib qho tsis zoo ion. Yog nws poob ib tug electron Nws dhau los ua ib qho zoo ion (saib nplooj 10 kom paub ntxiv txog ions).

Tsis tas li ntawd, koj paub li cas tus nqi ntawm ib qho atom? Cov nqi ntawm ib lub caij yog sib npaug rau tus naj npawb ntawm protons rho tawm tus naj npawb ntawm electrons. Tus naj npawb ntawm protons yog sib npaug rau cov atomic tus naj npawb ntawm cov khoom tau muab rau hauv lub sijhawm teem sijhawm.

Tom qab ntawd, ib tug kuj yuav nug, nws hu li cas thaum lub atom tau txais electrons?

Atoms suav nrog electrons , protons thiab neutrons. Thaum lub atom nce los yog poob ib hluav taws xob , nws attains tus nqi net thiab dhau los ua ion. Thaum twg electrons ploj (los yog pub dawb), qhov tshwm sim ion yog hu ua cation. Thaum twg electrons tau txais, lub resulting ion yog hu ua ib anion.

Yuav ua li cas tshwm sim thaum lub chlorine atom tau txais ib qho hluav taws xob nws hu ua dab tsi?

Muaj 18 electrons thiab 17 protons, yog li cov tshuaj chlorine atom tau ua tus nqi them tshuaj chlorine ion nrog tus nqi ntawm qhov tsis zoo (-1). Thaum nws siv rau qhov ntxiv hluav taws xob , ua a tshuaj chlorine ion, nrog tus nqi ntawm qhov tsis zoo (-1).
