What characterizes a face-centred unit cell?

Options

  1. AIt contains one constituent particle at its body-centre besides the ones at its corners.
  2. BIt contains one constituent particle at the centre of each face.
  3. CIt contains one constituent particle at the centre of each edge.
  4. DIt contains only constituent particles at its corners.

Correct answer

B. It contains one constituent particle at the centre of each face.

Step-by-step solution

A face-centred unit cell contains one constituent particle present at the centre of each face, besides the ones that are at its corners, as mentioned in the paragraph.
