Noble gases yog cov tsawg kawg reactive ntawm tag nrho cov ntsiab lus . 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 muaj tshwm sim nrog lwm yam cov ntsiab lus thiab tsim cov tebchaw.

Yog li ntawd, dab tsi pawg ntawm cov ntsiab lus yog qhov tsawg tshaj plaws reactive?

Pawg 18 : Noble Gases Group 18 cov ntsiab lus yog nonmetals hu ua cov pa roj (saib daim duab hauv qab no). Lawv yog cov tsis muaj xim, tsis muaj ntxhiab gases. Lawv lub zog sab nraud kuj tseem puv, yog li lawv yog qhov tsawg kawg nkaus cov ntsiab lus.

Kuj Paub, uas yog qhov tsawg tshaj plaws reactive hlau? Platinum

Yog li ntawd, dab tsi pawg ntawm cov ntsiab lus yog qhov reactive tshaj plaws?

Ob tug feem ntau reactive pawg ntawm cov ntsiab lus yog cov alkali hlau thiab halogens, vim lawv cov valence electrons. Cov pab pawg muaj 1 thiab 7 valence electrons, ntsig txog, ua rau lawv xav tau kev sib raug zoo rau ib yam dab tsi, kom ua tiav qhov ruaj khov ntawm 8.

Vim li cas helium yog qhov tsawg tshaj plaws reactive caij?

Chemical Properties of Noble Gases Noble gases yog cov tsawg kawg reactive ntawm txhua tus paub cov ntsiab lus . Tias yog vim li cas nrog yim valence electrons, lawv lub zog sab nraud yog tag nrho. Tab sis helium kuj tseem muaj lub zog sab nraud tag nrho, vim tias nws tsuas yog qib zog (zog qib 1) tuaj yeem tuav tau ntau tshaj ob lub electrons.

Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?

Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces

Vim li cas cov ntsiab lus hauv Pab Pawg 1 yog qhov cuam tshuam tshaj plaws?

Qhov feem ntau reactive nyob rau hauv pab pawg neeg 1 yog caseium vim hais tias thaum peb los ntawm sab saum toj mus rau hauv qab, qhov luaj li cas ntawm atom yog nce nyob rau hauv lub parallel nrog cov xov tooj ntawm electron, yog li lub zog tuav lub electron txo, thiab peb paub tias tag nrho cov alkali hlau muaj. ib qho hluav taws xob nyob rau hauv lub plhaub feem ntau yog li nws tuaj yeem yooj yim tshem tawm qhov ntawd

Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?

Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
