Presence of noble gases in nature

  1. Sall the noble gases exist in nature except Radon (Rn)
  2. Radon is a short-lived radioactive isotope, and is obtained by radioactive decay radium atoms.
  3. The presence of helium gas in natural gas is thought to be the result of the decay of radioactive substances.
  4. The most abundant noble gas element in air is argon (after oxygen and nitrogen).
  5. The most abundant noble gas element in nature is Helium because helium is an important component of the sun and other planets.
  6. Noble gases can be obtained by distillation of search air, except for radon which is obtained from the decay of radioactive radium atoms.
