Electron kev sib raug zoo nce sab laug mus rau sab xis hla lub sijhawm (tsis suav cov Noble gases) thiab txo qis thaum txav mus pab pawg nyob rau hauv lub periodic rooj. Yog li cov ntsiab lus nrog cov siab tshaj electron affinity yuav yog nyob rau sab xis saum toj kawg nkaus ntawm lub periodic rooj. Halogens feem ntau muaj cov siab tshaj electron affinity.
Tsis tas li ntawd, lub ntsiab lus twg muaj qhov zoo tshaj plaws electron affinity?
Txawm tias Fluorine muaj lub siab tshaj plaws electronegativity, Chlorine muaj lub siab tshaj plaws electron affinity thiab qhov no yog vim hais tias muaj ntau repulsion nyob rau hauv nruj packed 2p subshell ntawm Fluorine.
Ib sab saum toj no, lub caij twg muaj qhov tsawg tshaj plaws electron affinity? Periodic Trends nyob rau hauv Electron Affinity Chlorine muaj siab tshaj Eua ea thaum mercury muaj qhov qis tshaj . Eua ea feem ntau nce hla ib lub sij hawm (kab) nyob rau hauv lub sij hawm lub sij hawm, vim hais tias lub filling ntawm valence plhaub ntawm lub atom.
Ib yam li ntawd, koj tuaj yeem nug, pab pawg twg muaj qhov tsis zoo electron affinity tshaj plaws?
Yog li peb tuaj yeem xaus tias cov tswv cuab saum toj kawg nkaus hauv lub Halogens pawg yuav muaj feem ntau tsis zoo electron affinity. Lub ntsiab yog Florine.
Puas yog cov roj hluav taws xob muaj hluav taws xob muaj kev sib raug zoo?
Qhov no yog vim tag nrho cov Noble Gases muaj ua tiav valence hluav taws xob plhaub. Txij li thaum Noble Gases xa muaj uas 'zoo meej xwm txheej' ces lawv muaj ib kev sib raug zoo ntawm 0. Kev sib raug zoo yog qhov hloov ntawm lub zog ntawm lub atom thaum ib hluav taws xob yog ntxiv. Noble Gases yog nyob ntawm tus naj npawb zoo tshaj ntawm 8 electrons.

Nws txhais li cas thaum kev sib raug zoo ntawm kev sib raug zoo ua kev cuam tshuam?
Kev sib raug zoo ntawm ob tus neeg uas txhua tus neeg nyob ntawm thiab tau txais kev txhawb zog, txawm tias muaj txiaj ntsig lossis kev puas tsuaj, los ntawm lwm tus. ib qho kev sib cuam tshuam lossis kev sib raug zoo ntawm ob tus neeg, pab pawg, thiab lwm yam
Dab tsi yog qhov kev sib raug zoo ntawm kev ua lej ntawm qhov kev nyuaj siab khov kho thiab Mollality?
Kev nyuaj siab qhov chaw khov kho yog cov cuab yeej sib koom ua ke pom hauv cov kev daws teeb meem uas tshwm sim los ntawm kev qhia txog cov kuab tshuaj molecules rau cov kuab tshuaj. Cov ntsiab lus khov ntawm cov kev daws yog tag nrho qis dua li cov kuab tshuaj ntshiab thiab yog ncaj qha proportional rau molality ntawm cov kuab tshuaj
Dab tsi yog qhov teeb meem loj tshaj plaws ntawm kev siv cov kev tshawb fawb txog kev sib raug zoo?
Tej yam tsis zoo los yog kev tshawb fawb txog kev sib raug zoo muaj xws li: a. Lawv tsis tuaj yeem siv los tsim kom muaj kev sib raug zoo-thiab-tshuaj los yog kev coj ntawm kev cuam tshuam
Cov pab pawg twg hauv qab no ntawm kev tshawb fawb txog kev ua haujlwm ib puag ncig zoo sib xws?
Teb: D) Environmental activist, ib puag ncig tus kws lij choj Nyob rau hauv cov kev xaiv, ib puag ncig activists thiab ib puag ncig tus kws lij choj yog ib puag ncig science cov hauj lwm uas zoo sib xws. Lub hom phiaj tseem ceeb ntawm cov kws tshaj lij no yog kev tiv thaiv ib puag ncig
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
