What characterizes a body-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 each edge.
  4. DIt contains only constituent particles at its corners.

Correct answer

B. It contains one constituent particle at its body-centre besides the ones at its corners.

Step-by-step solution

A body-centred unit cell contains one constituent particle (atom, molecule, or ion) at its body-centre besides the ones that are at its corners, as stated in the paragraph.
