Atmospheric air is free from noble gases.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement claims that "atmospheric air is free from noble gases." To evaluate this, we need to identify what noble gases are and their presence in the atmosphere.

2. **Identifying Noble Gases**: Noble gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These gases are known for their low reactivity due to having a complete valence electron shell.

3. **Presence in the Atmosphere**: Contrary to the statement, noble gases are indeed present in the atmosphere. They are found in trace amounts, with argon being the most abundant noble gas in the air.

4. **Quantifying Noble Gases in Air**: It is estimated that noble gases make up about 1% of the volume of atmospheric air. Among these, argon constitutes the majority, while helium, neon, krypton, and xenon are present in much smaller quantities.

5. **Conclusion**: Since noble gases are present in the atmosphere, the statement that "atmospheric air is free from noble gases" is false.

**Final Answer**: The statement is false; atmospheric air contains noble gases, primarily argon, along with smaller amounts of helium, neon, krypton, and xenon.
