उत्तर
Atomicity refers to the total number of atoms present in one molecule of an element.
For example, argon is a noble gas and exists in a free state. One molecule of argon comprises only one atom. Therefore, the atomicity of argon is one.
Similarly, a molecule of chlorine gas has two atoms and it exists as a Cl2 molecule. Therefore, the atomicity of chlorine is two.
