Answer:
B) There are two atoms per unit cell.
Explanation:
In the face-centered cubic cell, there are spheres (which represent molecules or atoms) at the center of each of the six faces of the cube, in addition to eight corner spheres.
Because every unit cell in a crystalline solid is adjacent to other unit cells, most of a cell’s atoms are shared by neighboring cells.
A face-centered cubic cell contains the equivalent of four complete spheres or atoms—three from the six face-centered atoms and one from the eight shared corner spheres.
'' There are two atoms per unit cell'' is the correct answer.
