Question

calculate Number of atom in fcc unit cell
​

Answer 1

Explanation:

Face centered cubic unit cell:

in a face centered cubic unit cell:

8 corners ×18 per corner atom = 8×18=1 atom

6 face-centered atoms ×12 atom per unit cell = 3 atoms

Therefore the total number of atoms in a unit cell = 4 atoms

Answer 2

Answer:

The calculate Number of atom in fcc unit cell is

$4$

Explanation:

The cubic system is an isometric system this is the crystal system in which crystalline solid can be assigned.

In face centered cubic system

, unit cell of atoms are arranged in a manner such that

$\frac{1}{8}$

of an atom are at the 8 corners and one half of an item are at the six faces. So, the total number of atoms will be

$(8 \times \frac{1}{8} ) + (6 \times \frac{1}{2} ) = 1 + 3 = 4$

Hence, the correct answer is ,4
