Noble Gas vs Inert Gas
Noble gases yog inert gases, tab sis tag nrho cov inert gases tsis noble gases.
Noble Gas
Noble gases yog cov pab pawg ntawm cov ntsiab lus uas yog nyob rau hauv pawg 18 ntawm lub sijhawm. Lawv yog nonreactive los yog muaj cov tshuaj reactivity tsawg heev. Tag nrho cov tshuaj nyob rau hauv pawg no yog cov pa roj carbon monoxide, tsis muaj xim, thiab tsis muaj ntxhiab. Muaj rau lub suab nrov nrov. Lawv yog helium (He), neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), thiab Radon (Rn). Noble gases txawv ntawm lwm cov ntsiab lus vim lawv cov reactivity tsawg.
Qhov laj thawj ntawm qhov no tuaj yeem piav qhia los ntawm lawv cov qauv atomic. Tag nrho cov noble gases muaj ib tug tag nrho-filled txheej txheej. Hauv lwm lo lus, lawv tau sib tw octet uas txwv tsis pub lawv koom nrog tshuaj lom neeg. Qee lub sij hawm noble gases kuj hu ua pab pawg 0 gases, xav txog lawv qhov valency yog xoom. Txawm hais tias qhov no tau ntseeg ntau, cov kws tshawb fawb tom qab tau pom qee qhov sib txuas ua los ntawm cov roj noble. Yog li cov reactivity raws li qhov kev txiav txim Ne < Nws < Ar < Kr < Xe < Rn.
Noble gases muaj kev sib cuam tshuam ntawm atomic tsis muaj zog heev. Tsis muaj zog Van der Waals kev sib cuam tshuam yog kev sib cuam tshuam ntawm atomic rog uas tuaj yeem pom ntawm cov roj atoms zoo. Cov rog no nce ntxiv thaum qhov loj ntawm lub atom nce. Vim yog lub zog tsis muaj zog, lawv cov ntsiab lus melting thiab boiling point yog tsawg heev. Lub boiling point thiab lub melting point ntawm ib lub caij muaj me ntsis qhov zoo sib xws.
Ntawm cov roj uas muaj koob muaj npe, helium txawv me ntsis. Nws muaj qhov kub siab tshaj plaws ntawm qhov kub thiab txias ntawm txhua qhov. Nws yog qhov tsawg tshaj plaws. Nws qhia superfluidity. Yog li nws tsis tuaj yeem ua kom khov los ntawm kev ua kom txias raws li cov txheej txheem. Los ntawm helium mus rau radon hauv pawg, atomic radius nce vim qhov nce ntawm cov hluav taws xob thiab ionization zog txo vim tias kev tshem tawm cov hluav taws xob sab nrauv yuav yooj yim dua thaum qhov kev ncua deb ntawm nws los ntawm lub nucleus tau nce.
Noble gases yog tau los ntawm huab cua los ntawm txoj kev liquefaction ntawm gases thiab ces fractional distillation. Ntawm cov khoom no, radon yog radioactive. Nws cov isotopes tsis ruaj khov. 222Rn isotope muaj ib nrab neej ntawm 3.8 hnub. Thaum nws lwj nws tsim helium thiab polonium.
Noble gases yog siv los ua cov tub yees txias, rau cov hlau nplaum superconducting, thiab lwm yam. Helium yog siv los ua ib feem ntawm cov pa roj carbon monoxide, ua cov roj lifting hauv balloons thiab cov khoom nruab nrab hauv cov roj chromatography. Feem ntau noble gases yog siv los muab inert atmospheric tej yam kev mob rau kev sim.
Inert Gas
Inert gas yog cov roj uas tsis muaj tshuaj lom neeg. Qhov no suav hais tias yog nyob rau hauv cov txheej txheem muab, thiab thaum cov xwm txheej hloov pauv, lawv tuaj yeem rov ua dua. Feem ntau noble gases yog inert gases. Nitrogen kuj tseem suav tias yog cov pa roj inert nyob rau qee qhov xwm txheej. Cov no yog siv los tiv thaiv cov tshuaj tiv thaiv uas tsis xav tau tshwm sim.
Qhov txawv ntawm Noble Gas thiab Inert Gas yog dab tsi?
- Noble gases yog inert gases, tab sis tag nrho cov inert gases tsis noble gases.
- Inert gases tsis reactive nyob rau hauv tej yam kev mob whereas noble gases yuav reactive thiab ua compounds.
- Noble gases yog lub ntsiab lus, tab sis cov roj inert yuav tsis. Inert gases tej zaum yuav yog compounds.
