Question

The unit cell in which one constituent particle is present at the centre in addition to the particles at its corners is called ______ unit cell.

Answer 1

The unit cell in which one constituent particle is present at the centre in addition to the particles at its corners is called body-centred unit cell.

Explanation:

A body-centered cubic (bcc) unit cell has eight particles at the corners of the cube and one particle at the centre (not shared). This additional particle at the centre differentiates it from a simple cubic unit cell, which has particles only at the corners.
