Many elements crystallize with a unit cell that is hexagonally shaped (6 sided). The calculations of the unit cell dimension are not significantly more complicated than those for cubic unit cells. A hexagonal unit cell is shown below. 3/3 a?c Volume 2 6 atoms per unit cell The cell dimension "a" is twice the radius (r) of the atom. 2r=a. For most elements the dimension "c" is approximately 1.633x"a". The element cerium (Ce) crystallizes with a Simple Hexagonal unit cell. The density of a cerium is 6.689 g/cm3. Use this information to calculate the metallic radius of cerium in picometers (pm). 1 pm = 1×10-12 meters. You can assume that the dimension c=1.633-a
