Tom qab ntawd, neon nyob qhov twg hauv ntiaj teb?

Txawm tias neon yog qhov tseem ceeb tshaj plaws nyob rau hauv lub ntiaj teb no, tsuas yog 0.0018% nyob rau hauv ntim ntawm lub ntiaj teb cov cua. neon . Neon feem ntau yog pom nyob rau hauv daim ntawv ntawm cov pa roj nrog molecules muaj xws li ib leeg Neon atom. Neon yog ib qho tsis tshua muaj roj uas yog pom nyob rau hauv lub ntiaj teb lub satmosphere ntawm 1 feem ntawm 65,000.

Qhov thib ob, cov tshuaj neon puas muaj nyob hauv? Cov tshuaj . Neon yog ib qho inert heev, txawm li cas los xij, nws tau raug tshaj tawm los ua ib qho compound nrog fluorine. Nws tseem nug tau yog tias muaj tseeb tshuaj sib xyaw ntawm neon muaj, tab sis pov thawj yog mounting nyob rau hauv txaus siab ntawm lawv muaj nyob. Cov ions, Ne +, (NeAr) +, (NeH) +, thiab (HeNe +) yog paub los ntawm kev tshawb fawb optical thiab loj spectrometric.
