Options

A. 4
B. 5
C. 7
D. 8

Answer

To solve the question regarding the maximum number of halogen atoms in interhalogen compounds, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Interhalogen Compounds**:
- Interhalogen compounds are formed between two different halogen elements. Halogens include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).

2. **Identifying the Maximum Number of Halogen Atoms**:
- The maximum number of halogen atoms in an interhalogen compound can be determined by examining the known compounds.

3. **Analyzing Known Interhalogen Compounds**:
- One of the well-known interhalogen compounds is iodine heptafluoride (IF7).
- In IF7, there is one iodine atom and seven fluorine atoms.

4. **Counting the Total Halogen Atoms**:
- In IF7, the total number of halogen atoms is:
- 1 (from iodine) + 7 (from fluorine) = 8 halogen atoms.

5. **Conclusion**:
- Therefore, the maximum number of halogen atoms in interhalogen compounds is 8.

### Final Answer:
The maximum number of halogen atoms in known interhalogen compounds is **8**.
