Question

What is the atomicity of sodium?

Answer 1

Atomicity

• The number of atoms constituting a molecule is known as its atomicity.
• Atomicity is monoatomic if there is only one atom present, diatomic if there are two atoms present, triatomic if there are three atoms present, and so on.
• If there are more than four atoms present, the atomicity is polyatomic.

Atomicity of sodium

• Sodium $\left(\mathrm{Na}\right)$ is made up of only one atom.
• So, the atomicity of sodium is $1$ as it is monoatomic.
