Lithium metal crystallized in a body centred cubic crystal. If the length of the side of the unit cell of lithium is 351 pm, the atomic radius of the lithium will be `:`

A

152pm

B

75 pm

C

300 pm

D

240 pm

Text Solution

Verified by Experts

The correct Answer is:
A
For bcc structure
` = sqrt( 3) a = 4r` or `r = ( sqrt( 3))/( 4)a `
` :. r = ( sqrt( 3))/( 4) xx 351` = 151.98 `pm
