Nickel has a FCC crystal structure, an atomic radius of 0.125 nm, and an atomic weight of 58.68 g/mol. Compute and compare its theoretical density with the experimental value of 8.90 g/cm3
1. Above 882 oC, titanium has a BCC crystal structure, with a = 0.332 nm. Below this temperature, titanium has a HCP structure, with a = 0.2978 nm and c = 0.4735 nm. Determine the percent volume change when BCC titanium transforms to HCP titanium. Is this a contraction or expansion?
2. The element lithium has BCC packing with a body-centered cubic unit cell. The volume of the unit cell is 4.32 x 10−26 L. Calculate the density (g/cm3) of the element.
3. What is the volume of the unit cell? A metal crystallizes in a face-centered cubic lattice. The radius of the atom is 0.197 nm. The density of the element is 1.54 g/cm3
4. An element crystallizes in a body centered cubic unit cell. The radius of this element is
2.2 x 10−10 m, and the density is 0.991 g/cm3 How many moles of atoms are within one unit cell?
