Chapter 9, Problem 65QRT

Interpretation Introduction

Interpretation:

The density of Lithium metal having bcc arrangement under given condition has to be determined.

Concept Introduction:

The no. of atoms in a bcc unit cell is $2$ as each corner atoms are contributing $1/8$ to the unit cell and one atom is present at the body center.

The density is the ration between the mass of the unit cell (grams) and its volume $\left(c{m}^3\right)$.  Mathematically, it can be represented as given below.

  $d=\frac{m}{v}$

Where,

$v=$ Volume of cubic unit cell $=l^3$
