Number 12 Determine the coordination number for each ion: How many ions of each type are within one unit cell? Determine the face diagonal distance between the corner anions in the zine blend structure(figure B). Express this distance as a function of the cation and anion r_c and r_a that make up the crystal. Use this distance to determine the unit cell edge length, A, in terms of r_c and r_a. Given a Zn^2+ radius of 82 pm and aS^2-...
