Which of the following elements is a polyatomic molecule?

Correct option is B

Ans. (B)
Sol. Sulphur (S) is a polyatomic molecule. In its most stable form, sulfur exists as S₈, a molecule composed of eight sulfur atoms. Polyatomic molecules are molecules composed of more than two atoms, and sulfur in its most common form fits this definition.
(A) Chlorine – Incorrect, Chlorine (Cl) exists as a diatomic molecule (Cl₂), not polyatomic.
(B) Sulphur – Correct answer. Sulphur typically forms a polyatomic molecule like S₈ in its stable form.
(C) Argon – Incorrect, Argon (Ar) is a monatomic element and does not form a polyatomic molecule.
(D) Nitrogen – Incorrect, Nitrogen (N₂) is a diatomic molecule, not polyatomic.
