The element lead (Pb) crystallizes with a Face Centered Cubic unit cell. The density of lead is 11.3 g/cm3. Use this information to calculate the theoretical metallic radius of a lead atom in picometers. 1 pm = 1×10−12 meters [Note: The theoretical value for the metallic radius may be different from the experimentally determined value. Simply Googling the value of atomic radius may not yield the correct result]
