What is the atomicity of Chlorine?

Correct option is B

The correct answer is (b) Diatomic.
 Chlorine (Cl₂) exists naturally as a diatomic molecule, meaning each molecule of chlorine consists of two atoms of chlorine.
 Diatomic molecules are molecules composed of only two atoms, of either the same or different chemical elements.
 Chlorine in its diatomic form is a greenish-yellow gas with a strong odor and is commonly used in disinfection and bleaching processes.
Information Booster:
 Tetra-atomic: Molecules with four atoms. An example is P₄ (phosphorus).
 Poly-atomic: Molecules with more than two atoms. Examples include H₂O (water) and CO₂ (carbon dioxide).
 Monoatomic: Refers to elements that exist as single atoms, such as noble gases like helium (He) and neon (Ne).
