Definition for atomicity

The number of atoms present in a molecule of an element is known as the atomicity of that element. Based on the atomicity, molecules can be monoatomic, diatomic, triatomic or polyatomic.

Monoatomic molecules: molecules of some elements consist of only one atom

Example-helium(He), neon(Ne)

Diatomic molecule-:The molecules of certain elements consist of two atoms of the same element.

Example-oxygen(O2), chlorine(Cl2)

Triatomic molecules: The molecules of certain elements consist of three atoms of the same element.

Example-ozone(O3)

Polyatomic molecule: The molecules made up of more the three atoms are called polyatomic molecules

Example: phosphorus(P4)

Therefore the given statement is true, ie, polyatomic molecules are made up of more than three atoms.
