Which of the following elements has the maximum number of atoms in their molecular form?

Correct option is C

Ans. (c) S

Explanation:

• Sulfur (S) has the maximum number of atoms in its stable molecular form among the options provided. In its elemental state, sulfur commonly exists as S₈ molecules, meaning each molecule contains eight sulfur atoms.
• Phosphorus (P) often exists as P₄ (tetraphosphorus), with four atoms per molecule, so it has fewer atoms than S₈ in its molecular form.
• Neon (Ne) and Argon (Ar) are noble gases and are monoatomic, existing as single atoms in their molecular form, with only one atom per molecule.

Important Key Points:

1. Sulfur (S₈) has eight atoms in each of its molecular forms, more than any other option listed.
2. Phosphorus (P₄) is the next highest, with four atoms in its molecular form.
3. Noble gases like Neon (Ne) and Argon (Ar) exist as single atoms (monoatomic molecules).
4. Molecular structure impacts the physical and chemical properties of elements.
5. S₈ is the most common and stable allotrope of sulfur.
6. The molecular form reflects the stability of the allotrope under standard conditions.

Information Booster:

• Sulfur (S₈): Commonly forms a ring structure with eight atoms, known as octasulfur, which is stable at room temperature.
• Phosphorus (P₄): Exists in a tetrahedral structure in its white phosphorus allotrope, though red and black phosphorus have different structures.
• Noble Gases (Ne, Ar): Due to their chemical inertness, they exist in monoatomic form and do not readily bond with other atoms.
