Non-metals nyiam nce electrons kom tau txais Noble Gas teeb tsa. Cov muaj kuj siab Hluav taws xob affinities thiab siab Ionization zog. Cov hlau zoo li poob electrons thiab non-metals nyiam nce electrons , yog li hauv kev cuam tshuam nrog ob pawg no, muaj hluav taws xob hloov los ntawm cov hlau mus rau cov tsis yog hlau.

Tsis tas li ntawd, cov ntsiab lus twg thiaj li yuav tau txais electrons?

Cov ntsiab lus uas yog hlau yuav poob electrons thiab ua tau zoo ions hu ua cations. Cov ntsiab lus uas yog nonmetals zoo li nce electrons thiab ua tsis zoo them ions hu ua anions. Cov hlau uas nyob rau hauv kem 1A ntawm lub sij hawm lub sij hawm tsim ions los ntawm poob ib tug electron.

Dab tsi cov ntsiab lus tau txais electrons hauv tshuaj tiv thaiv? Nonmetals thiab metalloids yog li ntawd, nonmetals nce electrons sib raug rau cov mis = 8 - (pab pawg #). Chlorine, nyob rau hauv pawg 7, yuav nce 8 - 7 = 1 electron thiab tsim ib -1 ion. Hydrogen thiab helium tsuas muaj hluav taws xob hauv lawv thawj lub plhaub hluav taws xob.

Tib neeg kuj nug, cov ntsiab lus twg feem ntau yuav sib txuas nrog lwm cov ntsiab lus?

Cov tsis tshua ruaj khov noble gasses, suav nrog helium , neon , argon, krypton, xenon thiab radon, yog tag nrho cov nonmetal covalent ntsiab. Cov ntsiab lus no tsim kev sib raug zoo nrog ib leeg los ntawm kev sib koom electrons los ua cov sib txuas.

Cov pab pawg twg tau txais electrons yooj yim tshaj plaws?

Pab pawg 1 hlau nyob rau hauv lub sij hawm lub rooj uas muaj 1 valence hluav taws xob thiab poob lawv valence electrons tus yooj yim tshaj plaws , ua rau lawv feem ntau reactive hlau.
