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.

Lub ntsiab txhais ntawm lo lus hluav taws xob hluav taws xob yog dab tsi?
Npe. Cov hluav taws xob hluav taws xob txhais tau tias yog hluav taws xob hluav taws xob uas tso cai rau kev ua haujlwm kom tiav. Ib qho piv txwv ntawm lub zog hluav taws xob yog lub zog los ntawm lub qhov hluav taws xob ntsaws. YourDictionary txhais thiab siv piv txwv
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Qhov twg ntawm cov ntsiab lus hauv qab no feem ntau pom nyob rau hauv feem ntau cov chiv?
Cov tshuaj chiv niaj hnub suav nrog ib lossis ntau tshaj ntawm peb lub ntsiab lus tseem ceeb tshaj plaws hauv cov zaub mov noj: nitrogen, phosphorus, thiab potassium. Qhov tseem ceeb thib ob yog cov ntsiab lus sulfur, magnesium, thiab calcium
