Lithium forms body-centred cubic structure. The length of the side of its unit cell is 351pm. Atomic radius of lithium will be-

A

300pm

B

240pm

C

152pm

D

75pm

Text Solution

Verified by Experts

The correct Answer is:
C
For body-centred unit cell, `asqrt3=4r`
Given that, a = 351pm
Therefore, `r=(351xxsqrt3)/4=152`pm
