Polonium is the only element known to crystallize in the simple cubic lattice. (a) What is the distance between nearest neighbor polo- nium atoms if the first-order diffraction of X-rays with A = 1.785 Å from the parallel faces of its unit cells appears at an angle of 20 = 30.96° from these planes? (b) What is the density of polonium in this crystal (in g cm-3)?
