Correct Answer - Option 1 : 1
Explanation:
-
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.
