Hydrogen has three isotopes, the number of possible diatomic molecules will be

Options

A. 3
B. 6
C. 9
D. 12

Explanation

To determine the number of possible diatomic molecules that can be formed from the three isotopes of hydrogen, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Isotopes of Hydrogen**:
- Hydrogen has three isotopes:
- Protium (¹H or H)
- Deuterium (²H or D)
- Tritium (³H or T)

2. **List the Possible Diatomic Molecules**:
- Diatomic molecules can be formed by combining the isotopes with themselves or with each other.
- The combinations are:
- H₂ (Protium with itself)
- D₂ (Deuterium with itself)
- T₂ (Tritium with itself)
- HD (Protium with Deuterium)
- HT (Protium with Tritium)
- DT (Deuterium with Tritium)

3. **Count the Unique Combinations**:
- From the above combinations, we can see that there are a total of 6 unique diatomic molecules:
1. H₂
2. D₂
3. T₂
4. HD
5. HT
6. DT

4. **Conclusion**:
- Therefore, the total number of possible diatomic molecules that can be formed from the three isotopes of hydrogen is **6**.

### Final Answer:
The number of possible diatomic molecules will be **6**.
