Question

What is the atomicity of Chlorine and Argon?

Answer 1

Atomicity

• The number of atoms constituting a molecule is known as its atomicity.
• For example, an oxygen molecule$\left({\mathrm{O}}_2\right)$ is known as a diatomic molecule because it contains two oxygen atoms.

Atomicity of chlorine

• A chlorine molecule $\left({\mathrm{Cl}}_2\right)$ consists of two chlorine atoms.
• So, the atomicity of chlorine is $2$ as it is diatomic.

Atomicity of argon

• Argon (Ar) is made up of only one atom of that element.
• So, the atomicity of argon is $1$ as it is monoatomic
