Ions yog tsim thaum atom poob los yog nce electrons txhawm rau ua kom tiav txoj cai octet thiab muaj tag nrho sab nrauv valence hluav taws xob plhaub. Thaum lawv poob electrons , lawv tau txais txiaj ntsig zoo thiab muaj npe cations. Thaum lawv nce electrons , lawv raug nqi tsis zoo thiab muaj npe anions.

Raws li txoj cai, hom ion twg yog tsim thaum lub atom tau txais ib qho hluav taws xob?

Tsim ib qho Ion Ib qho atom uas poob ib los yog ntau tshaj valence electrons los ua ib tug zoo charged ion yog hu ua ib tug cation , thaum lub atom uas tau txais electrons thiab ua tsis zoo them yog hu ua anion.

Tsis tas li ntawd, yuav ua li cas thaum lub atom tsim ib ion? Txij li txhua tus electron muaj ib qho tsis zoo thiab txhua tus proton muaj ib qho zoo, atoms tsis muaj hluav taws xob tag nrho. Ib yog tsim thaum ib atom poob los yog nce ib lossis ntau dua electrons. Vim hais tias tus naj npawb ntawm electrons nyob rau hauv ib ion yog txawv ntawm tus naj npawb ntawm protons, ib ion nws muaj tag nrho cov nqi hluav taws xob.

Tsis tas li ntawd, hom atom twg ua tau zoo ion?

Ions -- Hluav taws xob them atoms -- tuaj yeem nqa ib zoo los yog tus nqi tsis zoo . Cov ions zoo yog cations thiab feem ntau yog hlau xws li tooj liab lossis sodium. Negatively them ions yog anions, tsim los ntawm cov khoom nonmetallic xws li oxygen thiab sulfur.

Dab tsi ntawm electrons tsim bonds?

Ionic daim ntawv cog lus daim ntawv thaum nonmetal thiab hlau pauv electrons, thaum covalent bonds tsim thaum electrons sib koom ntawm ob nonmetals. Ib ionic daim ntawv cog lus yog hom chemical bond tsim los ntawm electrostatic attraction ntawm ob oppositely them ions.
