Which statement about atoms arranged in a body-centered cubic (bee) crystal structure is correct ?

The center of the body of a bcc unit cell has one atom, while its eight edges each contain eight atoms. The body's central atom makes up every component of the unit cell. Each corner atom makes an eight-part contribution to the unit cell. As a result, there are atoms in the unit cell.

$\frac{1}{8}\times 8+1=2$.
