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

A

`151.8 "pm"`

B

`75.6 "pm"`

C

`300.5 "pm"`

D

`240.8 "pm"`

Text Solution

Verified by Experts

The correct Answer is:
A
Since lithium crystallises in a body centred cubic crystal,
Atomic radius `(r)=(sqrt(3)a)/4=a/(2sqrt(2))`
`=sqrt(3)/4xx351"pm"=151.8 "pm"`
