✓

Answer

In accordance with the number of atoms present in the molecules, they are classified as monoatomic, diatomic, triatomic and polyatomic molecules showing that they contain one, two, three or more than 3 atoms respectively.

Atomicity	Number of atoms per molecule	Example
Monoatomic molecule	1	Helium (He), Neon (Ne) metals (Fe, Cu)
Diatomic molecule	2	Hydrogen $\left( H _2\right)$, Chlorine $\left( Cl _2\right)$
Triatomic molecule	3	Ozone $\left( O _3\right)$
Polyatomic molecule	3	Phosphorous $\left( P _4\right)$, Sulphur $\left( S _8\right)$
