Qhov sib txawv tseem ceeb ntawm qhov zoo thiab qhov tsis zoo ion yog qhov zoo ion nqa cov hluav taws xob zoo thaum lub cev tsis zoo yog tus nqi hluav taws xob tsis zoo.
Ions yog hom tshuaj lom neeg uas tau txais los ntawm cov hluav taws xob poob lossis nce. Yog li ntawd, cov tsiaj no nqa cov nqi hluav taws xob. Cov nqi no tuaj yeem yog qhov zoo lossis tsis zoo. Li no, muaj ob hom ions ua zoo ions thiab tsis zoo ions.
Ion zoo yog dab tsi?
Cov ions zoo yog cov tshuaj lom neeg uas nqa cov hluav taws xob zoo. Peb hu ua cation. Cov cations no tsim thaum ib hom tshuaj nruab nrab poob ib qho hluav taws xob los ntawm nws cov qauv tshuaj. Cov ions zoo tuaj yeem yog atoms lossis moieties ntawm molecules.
Cov hom no muaj cov protons thiab electrons sib npaug sib npaug txhawm rau txhawm rau txo cov nqi. Yog li ntawd, thaum no atom los yog molecule poob ib tug electron, muaj ib tug ntxiv proton uas muaj ib tug zoo nqi. Qhov no muab cov txiaj ntsig zoo rau lub atom lossis molecule. Tsis tas li ntawd, cov ions no muaj ntau yam xws li monoatomic ions, diatomic ions lossis polyatomic ions raws li tus naj npawb ntawm cov atoms tam sim no nyob rau hauv hom ionic.
Ex: K+, Na+, NH4 +, thiab lwm yam.
Negative Ion yog dab tsi?
Negative ions yog hom tshuaj uas nqa cov hluav taws xob tsis zoo. Peb hu nws anion. Cov anions no tsim thaum ib hom tshuaj nruab nrab tau txais ib qho hluav taws xob los ntawm nws cov qauv tshuaj. Tsis zoo ions tuaj yeem yog atoms lossis moieties ntawm molecules.
Daim duab 01: Cerium Positive Ion thiab Sulfate Negative Ion
Cov hom no muaj cov protons thiab electrons sib npaug sib npaug txhawm rau txhawm rau txo cov nqi. Yog li ntawd, thaum lub atom los yog molecule tau txais ib qho hluav taws xob, muaj ib qho hluav taws xob ntxiv uas muaj qhov tsis zoo. Qhov no muab lub atom los yog molecule ib tug net tsis zoo nqi. Tsis tas li ntawd, cov ions no muaj ntau yam xws li monoatomic ions, diatomic ions lossis polyatomic ions raws li tus naj npawb ntawm cov atoms tam sim no nyob rau hauv hom ionic.
Ex: Cl–, Br–, SO4 -, thiab lwm yam.
Qhov txawv ntawm qhov zoo thiab qhov tsis zoo Ion yog dab tsi?
Cov ions zoo yog cov tshuaj lom neeg uas nqa cov hluav taws xob zoo. Cov ions no tsim thaum lub atom lossis molecule poob ib qho hluav taws xob. Yog li ntawd, cov ions zoo muaj ntau protons tshaj li electrons. Tab sis, tsis zoo ions yog hom tshuaj lom neeg uas nqa cov hluav taws xob tsis zoo. Cov ions no tsim thaum lub atom lossis molecule tau txais ib qho hluav taws xob. Yog li ntawd, cov ions tsis zoo muaj cov electrons ntau dua li cov protons. Cov no yog qhov sib txawv tseem ceeb ntawm qhov zoo thiab qhov tsis zoo ion.
Summary – Positive vs Negative Ion
Ions yog hom tshuaj lom neeg uas nqa hluav taws xob. Muaj ob daim ntawv ua ions zoo thiab tsis zoo ions. Qhov sib txawv ntawm qhov zoo thiab qhov tsis zoo ion yog tias cov ions zoo muaj cov hluav taws xob zoo thaum cov ions tsis zoo nqa cov hluav taws xob tsis zoo.
