🤓 Based on our data, we think this question is relevant for Professor Foley's class at UNG.
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.
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?
