Which of the following is polyatomic?
-
A.
Chlorine
-
B.
Nitrogen
-
C.
Sulphur
-
D.
Hydrogen
Correct Answer:
C. Sulphur
Explanation:
Polyatomic molecules are defined as those containing more than two atoms. Among the given options, sulphur is the correct answer because it naturally exists as a polyatomic molecule, most commonly in its octatomic form (S8), where eight sulphur atoms are bonded together in a ring structure. In contrast, chlorine (Cl2), nitrogen (N2), and hydrogen (H2) are diatomic molecules, consisting of only two atoms bonded together. Carbon exists in various allotropes like diamond or graphite which are giant covalent structures, but the term polyatomic in this context specifically identifies the molecular form of sulphur.
