What characterizes an end-centred unit cell?

Options

  1. AIt contains one constituent particle at the centre of each face.
  2. BIt contains one constituent particle at its body-centre besides the ones at its corners.
  3. CIt contains one constituent particle at the centre of any two opposite faces besides the ones present at its c
  4. DIt contains only constituent particles at its corners.

Correct answer

C. It contains one constituent particle at the centre of any two opposite faces besides the ones present at its c

Step-by-step solution

In an end-centred unit cell, one constituent particle is present at the centre of any two opposite faces besides the ones present at its corners, as stated in the paragraph.
