boiling points of noble gases increase from helium to Neon (T/F)

Answer

To determine whether the statement "boiling points of noble gases increase from helium to neon" is true or false, we can analyze the boiling points of the noble gases and the factors affecting them.

### Step-by-Step Solution:

1. **Identify the Noble Gases**: The noble gases in question are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), and Xenon (Xe).

2. **List the Boiling Points**:
- Helium (He): -269 °C
- Neon (Ne): -246 °C
- Argon (Ar): -186 °C
- Krypton (Kr): -157 °C
- Xenon (Xe): -108 °C

3. **Analyze the Trend**:
- From the list, we can see that the boiling point of Helium is -269 °C and the boiling point of Neon is -246 °C.
- As we move from Helium to Neon, the boiling point increases from -269 °C to -246 °C.

4. **Consider the Size of Noble Gases**:
- Noble gases have increasing atomic sizes as we move down the group in the periodic table.
- The increase in atomic size leads to an increase in the strength of Van der Waals forces (dispersion forces) between the atoms.

5. **Relate Van der Waals Forces to Boiling Points**:
- As the Van der Waals forces increase due to larger atomic size, the energy required to overcome these forces (which is reflected in the boiling point) also increases.
- Therefore, as we go from Helium to Neon, the boiling point indeed increases.

6. **Conclusion**:
- Since the boiling point of Helium is lower than that of Neon, the statement "boiling points of noble gases increase from helium to neon" is **True**.

### Final Answer:
The statement is **True**.
