Question

2. If the radius of a body-centered cubic unit cell is 2.55 x 10-8 cm, what is the length of the edge in pm

Answer 1

Explanation:

Given that,

The radius of a bcc unit cell is,
`r=2.55* 10^(-8)\ cm`

We need to find the length of the edge in pm.

We know that,

For a bcc unit cell, the relation between the radius and the length of the edge is given by :

Edge length,

`a=(4r)/(√(3) )\\\\a=(4* 2.55* 10^(-8))/(√(3) )\\\\a=5.88* 10^(-8)\ cm`

Hence, this is the required soolution.
