Question:
The number of molecules present in the unit cell of sodium chloride is:
The number of molecules present in the unit cell of sodium chloride is:
Show Hint
Each FCC unit cell of NaCl contains 8 molecules.
Updated On: Mar 26, 2025
- \( 5 \)
- \( 4 \)
- \( 8 \)
- \( 2 \)
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The NaCl unit cell is a face-centered cubic (FCC) lattice with 4 Na+ and 4 Cl− ions per unit cell, leading to:
\[ \text{Total molecules} = 8 \]
\[ \text{Total molecules} = 8 \]
