3.3 If the atomic radius of aluminum is 0.143 nm, calculate the volume of its unit cell in cubic meters. 3.10 Calculate the radius of a vanadium atom, given that V has a BCC crystal structure, a density of 5.96 g/cm3, and an atomic weight of 50.9 g/mol. 3.15 Below are listed the atomic weight, density, and atomic radius for three hypothetical alloys. For each determine whether its crystal structure is FCC, BCC, or simple cubic and then justify your determination. A simple cubic unit cell is shown in Figure 3.22. 2 1 IE 320 - Spring 2003 Introduction to Materials Science
3.34 Calculate the density of FeO, given that is has a rock salt crystal structure. 3.46 In terms of bonding, explain why silicate materials have relatively low densities. 3.51 Within a cubic unit cell, sketch the following directions: (a) ; (b) ; (c) ; (d) ; (e) ; (f ) ; (g) ; (h) .
