Yog tias muaj ib nrab nco txog cov tshuaj uas peb feem ntau nqa los ntawm peb cov hnub kawm ntawv, nws yog qhov inert lossis "noble" gases tsis hnov qab… chemical bonding piav qhia vim li cas. Cov pa roj carbon monoxide muaj tag nrho cov plhaub sab nraud ntawm cov hluav taws xob, thiab yog li tsis tuaj yeem faib lwm cov atoms 'electrons los ua cov ntawv cog lus.
Cov pa roj tsw qab ua li cas nrog?
Noble Gases
Lawv feem ntau yog cov tshuaj inert. Qhov no txhais tau hais tias lawv tsis hnov mob nrog lwm cov ntsiab lusvim tias lawv twb muaj qhov xav tau yim tag nrho s thiab p electrons nyob rau hauv lawv sab nraud (siab tshaj) qib zog. Cov ntsiab lus hauv pawg no yog helium, neon, argon, krypton, xenon, thiab radon.
Vim li cas qee cov pa roj tsw qab muaj zog?
Noble gases yog the tsawg kawg reactive ntawm tag nrho cov ntsiab. Qhov ntawd yog vim lawv muaj yim valence electrons, uas ua rau lawv lub zog sab nraud. Qhov no yog qhov ruaj khov tshaj plaws ntawm electrons, yog li noble gases tsis tshua hnov mob nrog lwm cov ntsiab lus thiab daim ntawv sib txuas.
Puas cov pa roj tsw qab zoo nrog dej?
The noble gases tsis hnov tsw nrog dej.
Pob cov pa roj tsw qab zoo nrog halogens?
Lawv react nrog hlau thiab lwm yam halogens kom tau txais ib qho octet Thaum qhov no tshwm sim, cov atoms ruaj khov thiab muaj cov roj teeb zoo. Noble gases tau sau valence shells raws li lawv tshwm sim nyob rau hauv cov xwm. Helium muaj ib tug duet ntawm valence electrons, thiab tus so ntawm noble gases muaj ib tug octet.
