Ions tshwm sim los ntawm atoms lossis molecules uas tau txais lossis poob ib lossis ntau dua valence electrons, muab lawv qhov zoo lossis tsis zoo. nqi . Cov uas muaj qhov tsis zoo nqi hu ua anions thiab cov uas muaj qhov zoo nqi hu ua cations.

Cov lus nug tseem yog, dab tsi yog anion?

Ib anion yog hom ionic nrog rau tus nqi tsis zoo Cov tshuaj lom neeg yuav yog ib qho atom lossis ib pawg ntawm atoms. Ib anion yog attracted rau lub anode hauv electrolysis. Anions feem ntau loj dua cations (zoo them ions) vim tias lawv muaj cov hluav taws xob ntxiv nyob ib puag ncig lawv.

Tsis tas li ntawd, ib qho piv txwv ntawm anion yog dab tsi? Anion : Thaum lub atom tau txais electron(s), nws yuav ua tsis zoo them ion hu ua anion . Piv txwv : chlorine tau txais ib qho hluav taws xob los tsim cov tshuaj chloride ion (Cl-), xws li hauv NaCl.

tus nqi ntawm AS yog dab tsi?

Anion ua dab tsi rau lub cev?

Anions stabilize cov ntshav siab, thaum cation nce ntshav siab. Anions txo cov ntshav qab zib, thaum cation nce ntshav qab zib. Anions ntxiv dag zog rau lub plawv dhia, thaum cation tsis muaj zog nws.
