Question

Explain why Chlorine forms diatomic molecule while Argon forms monoatomic molecule.

Answer 1

Chlorine forms diatomic molecule while Argon forms monoatomic molecule.

• Elements usually form molecules by sharing electrons with atoms of their own type to attain stability and fulfill valency.

• Chlorine atoms are one electron short of completing their octet

• Therefore, two atoms of chlorine share one electron each to form a diatomic molecule.

• In case of noble gases like argon, their valency is already satisfied hence they do not need to combine with other atoms.

• Hence they are monoatomic molecule.

Answer 2

Answer:

Explanation:

Argon is satisfied and chlorine is not satesfied by electron

Therefore it forms di atomi molecule

And argon forms mono atomic molecule
