What is the packing efficiency of fcc crystal structure?
What is the packing efficiency of fcc crystal structure?
74.0 \%
$68.04 \%$
$52 \cdot 4 \%$
$47 \cdot 6 \%$
Solution
For a Face-Centered Cubic (FCC) crystal structure, the packing efficiency is the percentage of volume occupied by atoms in the unit cell.
The packing efficiency for FCC is: 74.0%
This is the highest possible packing efficiency for any cubic arrangement, making FCC structures highly dense.
Answer: (1) 74.0%
