The ratio of effective number of atoms in a unit cell of fcc and bcc lattices is

Options

  1. A1: 2
  2. B4: 1
  3. C1: 4
  4. D2: 1

Correct answer

D. 2: 1

Step-by-step solution

The face-centered cubic (fcc) contains 4 atoms per unit cell while bccc (body-centered cubic) lattices contains 2 atoms per unit cell. Effective number of atoms in fcc Effective number of atoms in bcc = 4 2 =2: 1
