1. Vanadium crystallizes in a body- centered cubic lattice, and the length of the edge of a unit cell is 305 pm. What is the density of V? (hint: use the relationship between amu and grams to find mass; density = mass/volume). 1g= 1/6.022 x 10^23 amu.
2. The zincblende structures ZnS has the relatively large sulfide ions arranged at the lattice points of a face- centered cubic structure. The edge length of this cubic unic cell is 540.9 pm. Determine the density of zincblende.
3. Name the two unic cells whick occur in close packing of identical atoms. Beiefly explain how the two types of close-packed lattices of identical atoms differ, in terms of atomic arrangements.
4. Lead crystallizes in the face-centered cubic lattice. What is the corrdination number for Pb?
5. Ion crystallizes in the body- centered cubic lattice. What is the coordination number for Fe?
6. Compare and contrast the sodium chloride and cesium chloride structure types.
7. Describe the difference between metals, insulators, and semiconductors in terms of their resistivity vs temperature plots. Show how this relates to band theory by ilustrating and explaining band diagrams for each.
