WebMay 15, 2024 · This is the case of CCP (simple cubic closed packing) and FCC (face centered cubic closed packing) For CCP. Imagine sitting in a cubical room. Now place some big spheres on each of the vertices of the room such that the centre of sphere and the vertices coincide. You will see that some part of sphere goes outside the room itself. WebAug 15, 2024 · Alpha 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 p m 2 = 168 p m (b) Density is given by d e n s i t y = m a s s v o l u m e.
