Question

The unit cell present in abab closest packing of atoms is

Answer 1

Answer:

ABAB pattern suggests it is hcp lattice.

In a hcp lattice no. of atoms are 6

Thus total tetrahedral voids will be 12

Total octahedral voids will be 6.

Answer 2

Answer:

a unit cell is obtained by closed packing layers of atoms in ABAB ... and octahedral voids in the unit cell - Chemistry - The Solid State.
