Fundamental Concepts
3.1 What is the difference between atomic structure
and crystal structure?
Unit Cells
Metallic Crystal Structures
3.2 If the atomic radius of aluminum is 0.143 nm,
calculate the volume of its unit cell in cubic
meters.
Density Computations
3.9 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.
Crystal Systems
3.21 Sketch a unit cell for the body-centered
orthorhombic crystal structure.
Point Coordinates
3.25 Sketch a tetragonal unit cell, and within that
cell indicate locations of the ½ 1 ½ and ¼ ½ ¾ point
coordinates.
Crystallographic Directions
3.29 What are the indices for the directions indicated
by the two vectors in the following
sketch?
