Noble Gases

Lawv yog helium , neon , argon , krypton, xenon, thiab radon. Lawv ib zaug hu ua inert gases vim lawv tau xav tias yog tag nrho inert - tsis tuaj yeem tsim cov khoom sib xyaw. Qhov no yog ib qho kev ntseeg tsim nyog vim tias cov pa roj muaj octet tiav, ua rau lawv ruaj khov thiab tsis zoo li nce lossis poob ib qho hluav taws xob.

Xav txog qhov no, vim li cas helium yog inert gas?

Nyob rau saum cov noble cov pa yog me me helium (Nws), nrog lub plhaub uas puv nrog tsuas yog ob lub electrons. Qhov tseeb tias lawv cov plhaub sab nraud yog tag nrho txhais tau hais tias lawv zoo siab heev thiab tsis tas yuav hnov mob nrog lwm cov ntsiab lus. Qhov tseeb, lawv tsis tshua sib xyaw nrog lwm cov ntsiab lus. Qhov uas tsis yog-reactivity yog vim li cas lawv hu inert.

Tsis tas li ntawd, puas yog Argon roj inert? Argon Nws muaj kwv yees li tib yam solubility hauv dej li oxygen thiab yog 2.5 npaug ntau soluble hauv dej tshaj nitrogen. Argon yog xim tsis muaj ntxhiab, tsis muaj ntxhiab, nonflammable thiab nontoxic li khoom, kua los yog gas . Argon yog tshuaj inert nyob rau hauv feem ntau tej yam kev mob thiab cov ntaub ntawv tsis muaj kev ruaj ntseg tebchaw nyob rau hauv chav tsev kub.

Hauv qhov no, helium txawv ntawm neon thiab argon li cas?

1 Teb. Helium muaj lub plhaub sab nrauv ntawm tsuas yog 2 electrons Neon thiab Argon muaj cov plhaub sab nraud ntawm 8 lub tshuab hluav taws xob tag nrho peb tau ntim cov plhaub sab nraud thiab tsis tshua muaj kev ruaj ntseg.

Dab tsi yog kev siv cov roj inert?

Siv ntawm Noble Gases Cov cov pa roj yog siv ua form inert Cov huab cua, feem ntau rau arc vuam, tiv thaiv cov qauv, thiab tiv thaiv cov tshuaj lom neeg. Cov ntsiab lus yog siv nyob rau hauv cov teeb, xws li neon teeb thiab krypton headlamps, thiab nyob rau hauv lasers.
