Noble gases yog cov tshuaj nyob rau hauv pawg 18 ntawm lub periodic table. Lawv yog cov ruaj khov tshaj plaws vim muaj ntau tshaj plaws ntawm valence electrons lawv lub plhaub sab nraud tuaj yeem tuav. Cov tshuaj no muaj helium , neon , argon , krypton ua , xenon , thiab radon.
Ib yam li ntawd, neon argon krypton thiab xenon zoo li Helium li cas?
Zoo li lwm yam "noble" lossis "inert" gases, helium (Nws), argon (Ar) thiab radon (Rn), Neon , Krypton thiab Xenon nyob twj ywm hauv huab cua vim tias lawv tsis sib xyaw nrog lwm cov ntaub ntawv los tsim cov khoom sib xyaw ua kua lossis kua. Neon , Krypton thiab Xenon muaj nuj nqis rau lawv lub teeb emitting zog thaum hluav taws xob them.
Tsis tas li ntawd, dab tsi lub ntsiab zoo ib yam li argon? Noble gas Nonmetal Lub Sijhawm 3
Tsis tas li ntawd, qhov txawv ntawm neon thiab argon yog dab tsi?
Neon yog ib tug ci ntsa iab liab txiv kab ntxwv xim, thiab argon yog ib tug ntau dimmer lavender los yog lub teeb liab xim. Nyob rau hauv lub Cov txheej txheem sib cais roj, raws li lawv tau txais los ntawm peb cov huab cua, ob lub gases boils tawm ntawm lub txias thiab compressed kua xeev ntawm txawv siab.
Dab tsi yog cov ntsiab lus uas nws Ne thiab Ar muaj sib xws?
Pawg 8A (los yog VIIIA) ntawm lub sijhawm teem sijhawm yog Cov pa roj carbon monoxide lossis inert gases: helium ( Nws ), neon ( Ne ), argon ( Ar ), krypton (Kr), xenon (Xe), thiab radon (Rn). Lub npe los ntawm qhov tseeb tias cov no cov ntsiab lus yog zoo unreactive rau lwm tus cov ntsiab lus los yog compounds.

Dab tsi yog helium neon thiab argon muaj sib xws?
Kev piav qhia: Lub plhaub sab nraud ntawm Pawg VIIIA lossis cov roj hluav taws xob zoo ua rau kuv cov tswv cuab ntawm tsev neeg no (xws li Helium, Neon thiab Argon) ruaj khov tshaj plaws ntawm txhua lub ntsiab lus. Cov peb lub ntsiab lus no muaj cov cuab yeej zoo sib xws, ib qho chaw ruaj khov sab nrauv electron plhaub
Puas yog ob txoj kab sib luag zoo sib xws lossis tsis sib xws?
Yog tias ob qhov sib npaug piav txog kab sib luag, thiab yog li cov kab uas tsis sib tshuam, qhov system yog ywj siab thiab tsis sib haum. Yog hais tias ob qhov sib npaug piav txog tib kab, thiab yog li cov kab uas hla tus lej tsis kawg, lub kaw lus yog nyob ntawm thiab sib xws
Dab tsi yog qhov sib txawv ntawm kev sib tw thiab cov lej sib xws?
