Lithium crystallizes in a body - centred cubic crystal .If the length of the unit cell if lithium is `315`pm , the atomic radius of the lithium will be

A

`300.5` pm

B

`240.8` pm

C

`151.8` pm

D

`75.5` pm

Text Solution

Verified by Experts

The correct Answer is:
c
For bcc
`r =(sqrt(3)a)/(4) = (sqrt(3))/(4) xx 351 = 151.8` pm
