• The face centered cubic unit cell is composed of a cube with one atom at each of its corners and one atom in the center of each cube face. A FCC unit cell contains 4 atoms per unit.
• The body centered cubic unit cell is composed of a cube with one atom at each of its corners and one atom at the center of the cube. A BBC unit cell contains 2 atoms per unit.
In order to determine the unit cell of elemental tungsten, we will use the radius formula of each type of unit cell to find the density.
The radius of tungsten is 137 pm and the density is 19.3 g/cm3. Does elemental tungsten have a face-centered cubic structure or a body-centered cubic structure?
