Question
he number of atoms per unit cell, coordination number, and atomic packing factor, for a FCC crystal are……………
Solution
The number of atoms per unit cell for a Face-Centered Cubic (FCC) crystal is 4.
The coordination number for a FCC crystal is 12. This means each atom in the FCC structure touches 12 other atoms.
The atomic packing factor (APF) for a FCC is approximately 0.74. This is the highest packing factor possible, which means that in a FCC crystal, atoms occupy about 74% of the total crystal volume.
