Correct Answer - Option 1 : 1


  • Atomicity: The number of atoms present in a single molecule is termed as its atomicity. It can be classified into four types:

1. Monoatomic  2. Diatomic  3. Triatomic  4. Tetratomic

  • The octet rule refers to the tendency of atoms to have eight electrons in the valence shell or two-electron in He.
  • so, Inert gases have their complete octet.
  • All inert gases are monoatomic means their molecule contains only one atom. For example He, Ne, Ar, Kr, Xe and Rn.

So, Atomicity of inert gases is 1.
