The unit cell for tin has tetragonal symmetry, with a and b lattice parameters of 0.583 and 0.318 nm, respectively. If its density, atomic weight, and atomic radiusare 7.30 g/cm3, 118.69 g/mol, and 0.151 nm, respectively, compute the atomic packing factor.
Use foam balls and toothpicks to create a space-filling model of a simple cubic unit cell. The surfaces of the balls should be touching. On the cube above, draw a cut- away view showing only the atoms (or parts of atoms) inside one unit cell. Pay particular attention to where atoms touch (or not). One atom has been drawn in for you as an example. Number of atoms per unit cell - Coordination number (number of nearest neighbors)- Co A...
