Hello, over the past few days I've been looking at glowing ionization tubes on YouTube. there seems to be this innate correlation and association between ionization chambers and noble gasses, like xenon, argon and neon. i was wondering is it possible for oxygen or nitrogen to glow like them ?, both in a closed environment (tube), and in the open?. The only plausible explanation i can think of is that oxygen and nitrogen become unstable when stripped of electrons and will therefore quickly react with other nitrogen or oxygen atoms to regain that stable configuration. however is it possible to ionize them and maintain that glowing excited state? which are commonly seen in auroras. if so how much power is required, in terms of Mev or Ev classification?
