The properties of noble gases are:

  • These are colorless gases
  • These are odorless gases
  • These are mono-atomic gases composed of single atom only,
  • These gases are inert nature and show low reactivity due to complete filled \(ns^2np^6\) electronic configuration in their valence shells.
  • They have high ionization enthalpies and positive electron gain enthalpies
