Lead is fcc and its atomic radius is 0.175nm.What is its unit cell edge length |
|
Answer» OBTAIN the properties for lead, from table 3.1, “Atomic radii and crystal STRUCTURES for 16 metals” as follows: Atomic radii for lead  Crystal structure of lead is FCC. Since lead has an FCC crystal structure, obtain the relation for the volume of lead as follows: Write the equation for unit CELL length for FCC crystal structure.  Here, R is the atomic RADIUS of lead. Obtain the relation for the volume of the unit cell of the lead as follows:  Substitute  for.  ……. (1) |
