Question

The number of atoms per unit cell in a cubic crystal of an element belongs to simple,body centred and face centred cubic lattices would be



a)1,2,3

b)1,2,4

c)1,3,6

d)8,9,14

​

Answer 1

Answer: B) 4,2,1 is the answer

Explanation:

The face-centered cubic (fcc) has a coordination number of 12 and contains 4 atoms per unit cell. The body-centered cubic (bcc) has a coordination number of 8 and contains 2 atoms per unit cell. The simple cubic has a coordination number of 6 and contains 1 atom per unit cell
