If the radius of an atom of an elements ...

If the radius of an atom of an elements is `75` pm and the lattice type is body-centred cubic, what is the edge length of the unit cell?

A

`32.475` pm

B

`173.2` pm

C

`37.5` pm

D

`212.1` pm

Text Solution

Verified by Experts

The correct Answer is:
B
For bcc, `r=(sqrt(3))/(4)a`
or `a=(4r)/(sqrt(3))=(4xx75)/(1.732)=173.2` pm
