Palladium Oxide 90 K-2-4 a 1. The Figure shows the structure of PdO. The small circles represent palladium atoms and the I be circles oxygen atoms. The PdO, groups are planar. (a) What is the lattice type? (b) Indicate the primitive unit cell, and give a set of primitive translation vectors. (c) How many atoms are in a primitive unit cell? Give the coordinates of the basis atoms. (d) Give the Miller indices for a plane which contains planar PdO, groups. 2. Calcium Flourite, CaF2, has a structure based on the fee lattice and a basis with Ca at 0 0 0 and F's at 1 4 4 I and 3 3 3. Draw a projection diagram and sketch one conventional (cubic) cell of the structure
