Xe is the most reactive noble gas

Explanation

### Step-by-Step Solution

1. **Identify Noble Gases**: The noble gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements are known for their lack of reactivity due to their complete outer electron shells.

2. **Understand the Stability of Noble Gases**: The general outer electronic configuration of noble gases is \( ns^2 np^6 \). This configuration is stable, meaning they do not easily lose or gain electrons, which is why they are often referred to as inert gases.

3. **Examine Xenon's Reactivity**: Despite the general stability of noble gases, xenon is an exception. It can form various compounds such as \( XeF_2 \), \( XeF_4 \), \( XeF_6 \), \( XeO_3 \), and \( XeOF_4 \). This indicates that xenon can participate in chemical reactions, unlike other noble gases.

4. **Analyze the Factors Contributing to Xenon's Reactivity**:
- **Larger Atomic Size**: Xenon has a larger atomic radius compared to other noble gases, which means its outer electrons are further from the nucleus.
- **Effective Nuclear Charge (Z effective)**: The effective nuclear charge is lower for xenon due to its larger size, resulting in weaker attraction between the nucleus and the outer electrons.
- **Weak Electron Bonding**: The outer electrons in xenon are less tightly bound, making them more available for bonding.

5. **Conclusion**: Based on the above points, xenon is indeed the most reactive noble gas. Therefore, the statement "Xe is the most reactive noble gas" is **true**.
