1lead at room temperature has fcc crystal structure if the, Ask an Expert

Academics

1. Lead (at room temperature) has FCC crystal structure. If the atomic diameter of lead is 0.35 nm and the atomic weight is 207.2 g/mol, calculate the density of lead. Compare the result to literature values and discuss the possible origin for any deviation.
Crystalline solids:

1. a) Name and briefly explain three major types of defects that can be observed in crystalline solids.

2. b) Why do defects result in an increase of the energy of a material?

3. c) Experimentally it is observed that atoms that are located along grain boundary defects are more reactive that atoms that are located within a crystal grain. Briefly explain the origin for this observation.
