Question

1. Explain the behaviour of materials with ionic, covalent and metallic bonding. Explain why the material is behaving that way in relation to the bond. 2. Explain van der Waals bond. 3. What are the similarities and differences between FCC and HCP structures? 4. Show that the atomic packing factor for Body-Centered Cubic (BCC) crystal structure is 0.68. 5. What are the different application of x-ray diffraction? Discuss with examples. 6. What are the basis for the classification of elements in the periodic table? Discuss the different groups of the periodic table and their specific behaviours. 7. Compute the theoretical density of Aluminium which has an atomic radius of 0.143 nm and an FCC crystalline structure. Compare this density with its measured density (from the literature).
