Thaum atoms poob los yog nce electrons lawv npe. Yog hais tias lub atom nce, nws hu ua anion. Thaum ib tug atomloses ib hluav taws xob npe a. A sodium atom haseleven thiab atom muaj kaum xya electrons.

Tib neeg kuj nug, pes tsawg electrons puas sodium nce lossis poob?

Cations. Ib qho nruab nrab sodium atom zoo li yuav ua tiav ib qho octet hauv nws lub plhaub sab nraud los ntawm poob nws onevalence hluav taws xob . Cov cation ua nyob rau hauv no txoj kev, Na+, yog hu ua sodium ion kom paub qhov txawv ntawm lub caij. Lub plhaub sab nraud ntawm lub sodium ion yog ob hluav taws xob plhaub, uas muaj yim electrons hauv nws.

Tom qab, lo lus nug yog, pab pawg twg poob lossis nce electrons? Lub ntiaj teb alkali hlau ( pab pawg 2), xws li, Mg orSr poob ob e-'s kom tau txais kev teeb tsa ntawm Ne. Yog li ntawd, lub pab pawg 2 hlau zoo li muaj tus nqi +2. Nyob rau lwm sab ntawm lub sij hawm lub ntsiab lus nce electrons toresemble lub siab dua noble roj.

Tsis tas li ntawd, NA nce lossis poob electrons?

Ib qho cation yog ib qho atom uas tau poob qhov valence hluav taws xob thiab yog li ntawd muaj ntau qhov zoo protons dua li qhov tsis zoo electrons , yog li nws raug nqi zoo. Ib qho anion isan atom uas tau txais valence hluav taws xob thiab yog negativelycharged. Sodium yuav yooj yim poob uas ntxiv hluav taws xob . Thaum nws ua , nws ua tsis tau zoo.

Dab tsi yog sodium hu ua thaum nws poob ib qho hluav taws xob?

Cov Sodium ion. Hauv cov tshuaj tiv thaiv tus Sodium atom poob anelectron mus rau Chlorine atom. Yog li nws muaj ib qho proton ntau dua li nws muaj hluav taws xob thiab muaj tus nqi zoo ntawm +1 thiab itis tam sim no hu ua tus Sodium ion.
