The correct Answer is:
### Step-by-Step Solution 1. **Understanding Rare Gases**: - Rare gases, also known as noble gases, include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are located in Group 18 of the periodic table. 2. **Characteristics of Noble Gases**: - Noble gases are characterized by having a complete outer electron shell, which follows the electronic configuration of ns²np⁶. This configuration makes them very stable and unreactive. 3. **Monoatomic Nature**: - Due to their stability and complete octet, noble gases exist primarily as monoatomic gases. This means that they exist as single atoms rather than forming molecules (diatomic, triatomic, or polyatomic). 4. **Conclusion**: - Therefore, the rare gases are monoatomic in nature. ### Final Answer: The rare gases are monoatomic. ---
