Question

find the number of atoms in the fcc unit cell short question​

Answer 1

Answer:

8 x 1/8 = 1 and Face:6x ½ = 3, therefore total 4 atoms. The face-centred cubic (fcc) has a coordination number of 12 and contains 4 atoms per unit cell.

Answer 2

Ans)

ANSWER :-

4

EXPLANATION :-

Atoms At Corners = 1/8 * 8 (Because at corners 1/8th of an

atom is shared and there are

total 8 corners)

= 1

Atoms At Faces = 1/2 * 6 (Because at faces 1/2th of an atom

is shared and there are total 6

faces

= 3

Total = 1 + 3

= 4
