Question

Identify each unit cell as a simple cubic (or primitive-cubic), body-centered cubic, or face-centered cubic unit cell. Face-centered cubic is also known as cubic close‑packed. The first unit cell is a six sided cube with a sphere on each corner and a line along each edge of the cube connecting the center of each sphere with the centers of three other spheres. The second unit cell is a six sided cube with a sphere in the center of the cube, a sphere on each corner, and a line along each edge of the cube connecting the center of each corner sphere with the centers of three other corner spheres. The third unit cell is a six sided cube with a sphere in the center of each face, a sphere on each corner, and a line along each edge of the cube connecting the center of each corner sphere with the centers of three other corner spheres. Dashed lines connect each face sphere with the sphere on the opposite face. Answer Bank

Answer 2

body-centered cubic

face-centered cubic unit cell.

Step-by-step explanation:

The different types of lattice are determined by the orientation of the shapes in space. This means that the particles are oriented differently in the way they are packed. This phenomenon is known as the close packed structure. In the face-centered lattice, one atom or ion is surrounded by six other atoms in the structure. The unit cell, on the other hand, is a little bit different as there are few ions bound to the central ion.
