Chapter 11, Problem 11.68QE

Interpretation Introduction

Interpretation:

The number of silver ions present in FCC unit cell has to be calculated.

Concept Introduction:

Face centered cubic (Fcc)

In this crystal structure there are the eight lattice points at each corner as in the simple cubic but there are additional lattice points at the center of each face of the cube.

  $\text{FCC=}\frac{\text{Total}\text{Number}\text{of}\text{edges}}{\text{Number}\text{of}\text{atoms}\text{share}}\text{+}\frac{\text{Number}\text{of}\text{corners}}{\text{Number}\text{of}\text{atoms}\text{shared}}$
