Which non-reacting gas is found maximum in the air ?

Options

A. Argon
B. krypton
C. Helium
D. Neon

Explanation

To answer the question "Which non-reacting gas is found maximum in the air?", we can follow these steps:

### Step 1: Understand the Composition of Air
The atmosphere is composed of various gases. The major components are:
- Nitrogen (N₂) - approximately 78%
- Oxygen (O₂) - approximately 21%
- Other gases including carbon dioxide (CO₂), water vapor, and noble gases - less than 1%

### Step 2: Identify Non-Reacting Gases
Non-reacting gases are often referred to as noble gases. The noble gases include:
- Argon (Ar)
- Helium (He)
- Neon (Ne)
- Krypton (Kr)
- Radon (Rn)

### Step 3: Determine the Abundance of Noble Gases
Among the noble gases, Argon is the most abundant in the atmosphere. It constitutes about 0.93% of the air.

### Step 4: Conclusion
Since Argon is the non-reacting gas that is found in the maximum amount in the air, the answer to the question is:
**Argon (Ar)**

### Final Answer
The non-reacting gas found maximum in the air is Argon.
