Consider a metal crystal with simple cubic, fce, and bce structures. Assume that the nearest neighbour atoms (spheres) touch each other in the unit cells. The correct statement is
Options
- AThe percentage of the void space in different crystal structures follow the order: fcc < bcc < simple cubic.
- BThe number of atoms in the unit cell are 14,9 and 8 for fcc, bcc and simple cubic structures, respectively.
- CThe lowest percentage of the void space among the three crystal structures is approximately 48 %.
- DThe percentage of the void space in any of the above crystal structures will depend on the lattice parameter a
Correct answer
