Verified answer

:The number of atoms present in a molecule of an element is called its atomicity. Depending upon atomicity, molecules can be monoatomic (He), diatomic(O2), triatomic(O3), and tetra atomic(P4).

:It can be classified into:

• Monoatomic molecules: contains 1 atom eg: Xenon (Xe)
• Diatomic molecule: contains 2 atoms eg: Oxygen (O2)
• Triatomic molecule: contains 3 atoms eg: ozone (O3)
• Tetratomic molecule: contains 4 atoms eg:phosphorus (P4)
• Polyatomic molecule: contains more than 4 atoms eg sulphur (S8)
