DATE: October 8, 2011 DUE: October 14, 2011 ENG45, Solution to homework set #2. 1. Bond order in ionic materials. a. Determine from the periodic table the possible cationic charges for: Uranium, Thorium, Cerium, and Hafnium. Uranium can shed 6, 5, 4, 3, 2, 1 electrons in row seven. The first three of these are very relevant for real materials, but the complete list will also serve well as an answer to this question. Thorium can shed 4, 3, 2, 1 electrons in row seven. The first of these is very relevant for real materials, but the complete list will also serve well as an answer to this question. Cerium can shed 4, 3, 2, 1 electrons in row six. The first two of these are very relevant for real materials, but the complete list will also serve well as an answer to this question. Hafnium can shed 4, 3, 2, 1 electrons in row six without touching its 4f electron shell. The first of these is very relevant for real materials, but the complete list will also serve well as an answer to this question. b. Using the relevant ionic radii, determine the coordination number for the smaller
