A certain form of lead has a cubic closest packed (fcc) structure with an edge length of 492 pm. A) Calculate the value of the atomic radius for lead. Present your result in cm. You must show ALL your work and include units on ALL values to earn partial or full credit. B) Calculate the density of lead. Present your results in in g/cm3. You must show ALL your work and include units on ALL values to earn partial or full credit.
