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 … WebCrystal lattice has a resistivity against electric current since the conducting electrons are scattered by phonons. This phenomenon is referred to as intrinsic resistivity of crystalline …
