  5. Co

  • Co2 is carbon Dioxide, N is Nitrogen, o2 is oxygen and Co is cobalt. given the choices the answer none of the above. Gaseous ionization chambers are filled with one of the Nobel Gases. For example Helium, Argon, Xenon, Radon, Krypton, and Neon. Typically the gas is either Argon or Helium both of which are inert gases. so... With that in mind, from the options given for the question I would choose Co2 .
