Potassium crystallises in bcc lattice
Web2 Oct 2014 · Potassium crystallises in a Body Centered Cubic way. It's density is 0.853 g/cm3, its molar mass is 39.9 g/mol. Calculate the number of atoms per cell and its atomic packing factor. My argument is this: This question makes no sense because BCC means it has 2 atoms per cell and has a 0.68 Atomic packing factor. WebA BCC unit cell contains two atoms: one-eighth of an atom at each of the eight corners (8 × 1 8 = 1 (8 × 1 8 = 1 atom from the corners) plus one atom from the center. Any atom in this …
