A compound \( M X \) has cubic close packing (ccp) arrangement of \( X \). Its unit cell structure is shown below. The empirical formula of the compound is
Show Hint
In cubic close packing, each unit cell has an equal number of \( M \) and \( X \) atoms when the formula is \( M X \).

- \( M X \)
- \( M_2 X \)
- \( M X_2 \)
- \( M_3 X_4 \)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Analyze the structure.
In a cubic close packing (ccp) structure, each unit cell contains one atom of \( M \) and one atom of \( X \). Since the number of atoms of \( M \) and \( X \) are in a 1:1 ratio, the empirical formula is \( M X \).
Step 2: Conclusion.
Thus, the empirical formula is \( M X \).
Final Answer: \[ \boxed{M X} \]
