Question

Calculate the total number of atoms present in a body centred cubic unit cell having 6 particles at edges and 5 particles at the corners(plz no spam)
the ans is 24 but plz explain

Answer 1

The number of atoms contained in one body-centred cubic unit cell of monoatomic substance is 2

8 atoms are present at 8 corners of a bcc unit cell. Each atom contributes one eigth to the unit cell. Total contribution = 8× 1/8 = 1

1 atom is present at body centre of a bcc unit cell. The atom contributes fully to the unit cell. Total contribution = 1
