Best answer
  • Group 18 is the last group of p-block and include noble or inert gases.
  • They have closed valence shells (complete duplet in the case of ‘He’ and complete octet in the case of the other noble gases).
  • Therefore, they show very low chemical reactivity and thus, do not participate in chemical reactions readily.
