Answer to Question #21664 in Physical Chemistry for susan1991

Question

Vanadium (V) crystallizes in a body-centered cubic lattice (the vanadium atoms occupy only the points of the network). How V atoms are present in a unit cell?

Answer 1

The unit cell for BCC (body-centered cubic )should have a total of 2 atoms.The unit cell has 1/8 of an atom at each corner and one atom in the center.

So 1/8 nitrogen * 8 + 1 boron = 2 total atoms.

Two V atoms are present in unit cell
