Density of a Unit Cell – Explanation and FAQs - Vedantu
WebAlpha polonium crystallizes in a simple cubic unit cell: (a) Two adjacent Po atoms contact each other, so the edge length of this cell is equal to two Po atomic radii: l = 2 r. Therefore, the radius of Po is r = l 2 = 336 pm 2 = 168 pm. (b) Density is … Web• Rare due to poor packing (only Po [84] has this structure) • Close-packed directions are cube edges.
