Qi) Here is a BBC unit lattice. Using the full sphere model, calculate the relative amount of area that is occupied by atoms with their center in the plane shown below (diagonal across the body). This is called the planar packing factor, equivalent to the atomic packing factor in 3D. Also mark the octahedral sites present on the plane. Bec Q2) Zinc has an HCP unit cell for...
