Concept

Problem: The densities of the elements K, Ca, Sc, and Ti are 0.86, 1.5, 3.2, and 4.5 g/cm3, respectively. One of these elements crystallizes in a body-centered cubic structure; the other three crystallize in a face-centered cubic structure.Which one crystallizes in the body-centered cubic structure?

FREE Expert Solution

A body-centered cubic (BCC) unit cell is composed of a cube with one atom at each of its corners and one atom at the center of the cube. While the face-centered cubic lattice contains an atom in each of the face of the cube and an atom in each of the corners.
