Tsim ib qho Ion Ib lub atom uas poob ib lossis ntau dua valence electrons los ua ib qho txiaj ntsig zoo ion yog hu ua cation, thaum lub atom uas nce electrons thiab ua tsis zoo yog hu ua an anion.
Dab tsi yog tsim thaum lub atom nce electron S ?
Thaum lub atom nruab nrab nce lossis poob ib qho hluav taws xob nws dhau los ua an ion.
Yuav ua li cas rau lub atom yog tias nws nce electron?
Tsis zoo li protons, electrons tuaj yeem txav ntawm atom mus rau atom. … Yog hais tias nws tau txais ib qho hluav taws xob ntxiv, nws yuav raug nqi tsis zoo thiab paub tiasua anion. Yog tias nws poob ib qho hluav taws xob, nws yuav raug them zoo thiab paub tias yog cation.
Dab tsi yog tsim los ntawm atom nce lossis poob electrons?
Ib lub atom ua an ion thaum nws nce lossis poob electrons. Cov ions uas tau tsim thaum lub atom poob electrons yog qhov zoo vim tias lawv muaj ntau protons nyob rau hauv lub nucleus tshaj electrons nyob rau hauv lub huab electron. Cov ions raug them zoo yog hu ua cations (hais CAT-ions).
Puas atom plam electrons?
Qee zaum atoms nce lossis poob electrons. Lub atom ces poob los yog nce nqi "tsis zoo". Cov atoms no hu ua ions. Positive Ion - tshwm sim thaum lub atom poob ib qho hluav taws xob (tus nqi tsis zoo) nws muaj protons ntau dua li electrons.
